    FPS in V4.5 (waiting for a fix)

    Having worked in several software developement business I've garnered some pretty good hindsight in software release practises. And testing is always a pain, but sooner or later you'll reach a testing stage where you'll think the software is good enough (no show stoppers you're aware of) and release, because basically you cannot just keep on testing indefinitely. Of course as soon as you release many more people will be using the software in different circumstances and typically there are a whole new wave of problems to deal with that you never suspected even existed. So onwards for the next release fixing those new probs and building new features at the same time. I've seen release schedules, where identified issues and new features are added each week, can be hard to get a stable build though. I've also seen where managment states a release date and come hell or high water out the software goes and then the org deals with any issues post release. Still others don't do any testing at all other than what the developer may do themselves (hint, never a good idea to rely on a developer who is already under pressure, to subjectively test). I've even seen software with years of investment costs and time just abandoned because of a change of management direction, FSX would be a good example but there are many more within Enterprise level software development that you'll never hear of. So how do enterpise level orgs deal with the above types of issues? They run multiple builds e.g. Test/Dev/Prod and always have a rollback option. Not every one has the luxury to run multiple builds but for P3D it is the Client installer that provides rollback, install just the client, test under a variaty of conditions and if OK continue, otherwise rollback to the previous client. I updated the client and just the additonal third party items needed, tested and noted issues, read forums, found out what was going on and then rolled back to v4.4 client so I could still happily sim while awaiting LM to deliver a fix.

    P3D multicore usage anomoly

    I've heard the high usage of one core described as being the main controller core. And for myself killing core zero and then re-enstating it does nothing other than push the main core thread onto a different core where it still happily uses as much of the Core's CPU % as it needs. What I do is use Process Lassoo, being the nice handy tool it is you can push literally everything off core zero apart from P3D. That way there is no contention of core zero and P3D has it practically all to itself. Usually I go a bit further and push everything to Cores 4~7 so that P3D can use 0~3 for it's own use and run P3D with a priority of Above Normal. But then again I also overclock and like trying out little tweeks and such in an effort to gain smoothness without overloading the GPU/CPU. The biggest difference was to go to a monitor with a 30 Hz capability because then I could VSync and achive a very smooth 30 fps, that was before I found out about RTSS though and I might have stuck with my old 60 Hz monitor had I known about RTSS and its capablity to perform a 1/2 vsync rate (e.g. (60 Hz / 2) = 30 fps or (30 hz / 2) = 15 fps). In actuality although it's difficult to achive a high enough frame rate to vsync in P3D once a few addins have been installed but I do have games that are much harder on both GPU and CPU, e.g. Crysis 1, same deal great fps while stock, but the time immersion, Ai and HD packs are installed the max frame rate is ~24 fps, and SkyRim Special Edition, I have around 150 odd mods installed all of which chew on the CPU/GPU, however both of these are still highly playable and feel much smoother than P3D does anyway probably because P3D has a hard time maintaining a steady framerate. Just waiting on those Ryzen 3 3850X with 32 threads @ 5.1 GHz to come out then I'll begin planning a new build, hopefully NVidia prices will have come down by then as well. Cheers

    P3D multicore usage anomoly

    Vsyncing @ 30 Hz will reduce load, fairly signiticantly for the GPU, not so significantly for the CPU and that's just because of the way the ESP engine works. It's all because a 30Hz vsync = 30 FPS (in P3D it's a wobbly 30 FPS though) and it's less work for the GPU to maintain 30 FPS than 60 FPS. RTSS use is described pretty well in the linked thread. Hopefully LM will be able to improve FPS performance in coming versions athough P3D is quite a bit ahead of where FSX was. I took a flight from 11S in FSX-SE just to see waht it was like, OOM in no time and low FPS (although in FSX they would be considered OK) made me realise how far P3D has come, but then again so have the othere sims improved. Cheers
  4. Hey folks, Just thought I share a little discovery. I was giving some thought to if I I could further improve P3D and it's already smooth 30hz-30fps vsync'd operation and that got me thinking about smooth motion functions of TV's to bring 24 fps up to 60 fps for smooth playback and if there were any similar options for applying to P3D. As it turns out games do not lend well to such motion interpolation due to the way they output frames, but I decided to take a good look through all the options in the NVidia inspector anyway. And found "SILK Smoothness" which although it doesn't bring the fps up to 60 fps, it certainly trims the rough edges off P3D, so much in fact that my already smooth 30hz-30fps now feels a lot closer to 60 fps. Will it prove to be the *perfect* tweek? Not at all, but it is a further effective tweek in the search for improved P3D performance. ====================================== SILK Smoothness Silk reduces stutters in games caused by variable CPU or GPU workloads by smoothing out animation and presentation cadence using animation prediction and post render smoothing buffer. • Off – Silk is disabled. • Low – Moderate smoothing is enabled and most microstutter is eliminated. • Medium – Many stutters and hitches are removed in typical games. • High – More smoothing is applied and may result in observable input lag. • Ultra – Maximum smoothing is applied and most stutters and hitches in games are eliminated. Lag may be unacceptable in some games. Note: Selecting High or Ultra settings for silk can increase noticeable lag when playing, and may not be appropriate for first person shooters or competitive gaming. ====================================== The setting is located in the NVidia Inspector under "Other" and there are only 5 settings as hex 0 to 4. Just choose the value to trial from the drop down. I started with trialing 4 (Ultra) and then trialed others to see how P3D changed. Note: I running a 1070Ti and version 418.67 GPU drivers. As usual results may vary, but it is an easy tweek to trial out. Cheers

    Max GPU Load

    Hey Mate, You need to set a screen mode and size (outside of P3D) that runs @ 60 hz and then choose that screen size in P3D. For example my monitor will output 1080P, 1920 x 1080 at the following refresh rates. 23 hz, 24 hz, 30 hz, 50 hz, 59 hz and 60 hz Then if you follow the settings for RTSS as described and also in the video (there is both RTSS and P3D example settings) you should be right to go. Note there will be no need to limit in the NVidia inspector because by vsyncing at half the 60 hz refresh rate you're automatically limited to 30 fps and setting a limit anywhere else is redundant. Cheers

    Yeah which is why I have different tuned profiles configured for different flying situations. Just select from the dropdown and pick a profile that's going to work for the situation, even in mid flight. Pity automation cannot be applied to vary settings dynamicaly though. Cheers

    GTX 1070 Ti or RTX 2060?

    Affordability and availablity does factor into purchasing. The 2080Ti had just come onto market when I purchased the 1070Ti and was pushing up around the high end between $2000.00~$3000.00 AUD mark (still mostly over 2 grand atm). Even the 1080Ti were around the $1300~$1800 mark and still are if you can find one. And the 1070Ti was totally the only affordable offering @ $599.00 AUD at the time. Probably why the 2070 is a top seller being affordable @ ~$769.00 AUD. So there are no good or bad ideas, just the best that can be afforded. Cheers

    GTX 1070 Ti or RTX 2060?

    Hi There, I have the 1070Ti and I find it OK, although I do wish I could have afforded a1080Ti (or 2 x 1070Ti's) at the time of purchase. Alas this new batch of cards from NVidia are either uber expensive, or are a step backwards in one way or another, probably why the 1070Ti is holding its value. These videos demonstrate the use of P3D and my 1070Ti card, plus now that I've achieved a stable CPU overclock I've turned my attention to the GPU and am achieving some quite noticable and reliable overclocking.

    Max GPU Load

    Hi 24CarrotMagic, GPU usage is going to be subjective depending on a whole lot of various items. Here's a link to a free tool I use to monitor CPU, temps and GPU use, it can help you gain an understanding of how settings changes affect GPU/CPU use. https://www.cpuid.com/softwares/hwmonitor.html Monitor Hz rate (refresh rate) vs fps Essentually the higher the frames per second, and the higher the GFX settings and the greater the draw distance equals higher GPU use. For example, lets say we have a 60 hz monitor - and we can either set a locked frame rate or run unlimited frames within P3D. However running a locked frame rate in P3D is not the best as P3D isn't really setup to actually achieve the FPS set on the slider and the result is a poor performing sim. So the next best option is to set the fps to unlimited. P3D does manage this very well and automatically works as hard as it can to get the maximum fps result, however the fps will jump around and although fps will be high it generally won't be very smooth. There is also the P3D option of vsync with triple buffering which will sync the frame rate to match the monotor hz (60 hz = 60 fps) and this actually works very well for providing a very smooth flying experience. However with a 60 hz monitor you'll need P3D to be able to maintain fps of around 30% higher than 60 fps (for a 60 hz monitor) in order to leave some free overhead for the vsync to not drop out, as if the fps drops below 60, so to does vsync and a jarring judder and stutters occur. So what does all the above have to do with GPU load? Well, trying to maintain the highest fps on a 60 hz monitor with even resonable settings in P3D tends to max the GPU and results in stutters. Plus some settings in P3D will affect GPU use more than others, for example vegetation shadows will kill GPU use especially in low light conditions (dusk/dawn where shadows are long) simply because if you're in a area with trees - there are typically lots of trees to have to draw shadows for. But if you can set the monitor to 30 hz and use vsync (30 hz = 30 fps), the GPU no longer has work as hard at the same P3D settings values and thus a smooth flying vsync'd sim is possible. In fact you can often ramp up the settings and still keep P3D flying smooth. But what if it is not possible to set a 30 hz screen mode? Well there are a few tools that can help, there is the NVidia 3D setting of vsync at half the refresh rate (I never had much luck with that though) and there is RTSS (Riva Tuning Statistics Server) which can do the same and help keep your GPU use under control while also vsyncing at half the monitor refresh rate. Take a look at this thread which has discussion on RTSS also includes a sample video with the P3D settings used for the video. https://www.avsim.com/forums/topic/552108-stuttering-every-few-seconds P3D Profiles One of the main consumer of GPU and fps in P3D is the draw distance, being the wider the draw distance, the more resources will be taken by both CPU and GPU, it's a bit like doubling a resolution increases resource requirements by 4. This is where P3D profiles comes in handy (although they are some what clumsy to maintain). You create a nice standard configuration then save it as a profile. I've created a bunch based on draw distance mostly and tune accordingly. e.g. 0.PhototReal (has practically all setting maxed) 1.VeryHigh, 2.High, 3.Medium, 4.Low etc. The Clumsy part is you cannot browse/select the profile to save, you'll need to type it in so best to keep the name simple, hopefully LM wil fix this lack of UI functionality in the future... The profiles are held in \Documents\Prepar3D v4 Files\ as the name you've given them and that's why I prefix with a number for ordering and to make them easy to find. Essentually they are cut down prepar3d.cfg files and you can edit manually with a text editor and also rename them outside of P3D itself without drama. They can be used to create alternative settings that can easily be switched over to while flying. Example Pics I'll finish off now with two P3D pics, both are P3D paused with the exact same photoreal scenery (BlueSky) running my "0.PhotoReal" config profile, the difference being one is @ 60 hz unlimited frame rate, the other is @ 30 Hz vsync'd unlimited frame rate ((30hz vsync'd = 30 fps - this is the only change), Check out the GPU use stats. https://steamcommunity.com/sharedfiles/filedetails/?id=1704214789 https://steamcommunity.com/sharedfiles/filedetails/?id=1704235003

    Thinking about it, you could trial increasing the FIBER_FRAME_TIME_FRACTION value and see if it helps with the loading. 0.33 is the default, so try higher values, e.g. along the lines of 0.66 or 0.99. Also here is a quick video showing the use of RTSS and P3D. Cheers
  12. Sounds like your GPU/CPU is getting overloaded i.e. maxing out @ 100% Try using a tool to view what sort of use your GPU/CPU is being put to and then adjusting the P3D settings to hopefully solve. Here'sa tool I use. https://www.cpuid.com/softwares/hwmonitor.html Cheers

    I didn't say that it would be a cure all, just that there was nothing stopping you from limiting inside of P3D. Anyway I'd still use unlimited in P3D and the half sync rate 30 fps limit and see how your autogen goes then, as P3D is still going to have less load given it is sync'd to 30 fps via the half hz rate. Cheers

    There is nothing to stop you from also limiting in P3D, just as long as P3D can reach 30 FPS (60 hz rate divided by 2), otherwise yeah syncing to the monitor hz scan rate is of no use if P3D cannot maintain the equivelent fps. Cheers

    Do you have this setting? Prepar3d.cfg [GRAPHICS] // controls the quality of the shadows, default is OPAQUE_SHADOW_TEXTURE_SIZE=2048. Try values of 4096 and 8192 to improve the low quality of the VC shadows. Comes at a computational cost. OPAQUE_SHADOW_TEXTURE_SIZE=4096 Cheers

    Yes positively the ideal is to keep your GPU use below 100% and this is where the use of the half refresh rate sync locking the fps @ 30 FPS provides for less load on the GPU than otherwise would occur. All means that will a bit of tuning many settings can be ramped up for a better looking sim. One thing I've leant is to turn off vegetation shadows as many trees = lots of GPU load for shadowing, especially at dusk/dawn situation where shadows will be long. Cheers

    There is no need to set the frame rate limiter within RTSS as the "Scanline sync x/2" means divide by 2 so when the screen refresh rate of 60 is divided by 2 we have 30. Thus 30 fps will be P3D's frame rate and no need for other types of limiting. Of course you can set it if you want but the frame rate will already be limited to 30 fps (half of the refresh rate assuming 60 hz). Cheers

    Hey Anshu, great find! Almost as smooth as actualy having a 30 Hz monitor, certainly if I was runing a 60 Hz monitor I'd be using this vsync option and now that I've experimented with it I'm surprised LM didn't include such a half vsync option in P3D itself as it would be somewhat of a game changer for smoothness given the otherwise difficulty in achieving high enough fps to match higher monitor refreshrates (such as 60 hz), especially after loading in a few GFX addons. Found a couple of things. 1), I couldn't get the on screen display to show, but don't really care. 2), I was running reshade, however RTSS wouldn't work with it, not a biggy as I was only running three shaders. 3), I think the reason it is not quite as smooth as P3D's vsync @ 30 Hz is because P3D's vsync also offers a triple buffer, but no matter, RTSS's ability to lock the framerate by vsyncing @ half the refreshrate is clearly a winner for those running 60 hz monitors. 4), With the frame rate locked via RTSS's half vsync to 30 fps there's increased capacity available in the GPU to ramp up those settings for a better looking sim. Win and win again 🙂 Cheers

    Does 1/2 refresh rate work?

    Hi, Been experimenting this this and have found the following. 1), yes locking the frame rate in P3D typically doesn't actually get you the frame rate you've set. That said I experimented with increasing the value of [Display] TEXTURE_BANDWIDTH_MULT= The P3D default is 30, FSX-SE is 160, so I went to 160 and then incremented by 100 till I saw no appreciable changes, 760 was the result and now when I set 30 fps in the P3D slider. 30 fps is what I get. Would proably depend on an individual machine and the silicon lottery but worth a go and it's easy to experiment with. The advantage I see of it all is the frame rate is much more stable, and doesn't jump all over the place so much as when v-sync and unlimited frames is on. 2), To get the NVidia half refresh rate working I needed to disable Aero (I run Windows7) for which I wrote a small toggle script, so the 1/2 refresh tweak does work, although 30 Hz and v-sync is better but if I didn't have a 30 Hz monitor myself I'd use the 1/2 refresh tweak. 3), Even with 30 Hz, v-sync and unlimited framerate set a lot of spare overhead is needed as if the framerate drops under 30 v-sync drops off and a sudden and distacting "frame rate jump" occurs. (this is where the frame rate slider in P3D can help). For those interested a 1080p monitor that can support a custom 30Hz value is the Dell MultiSync MHL IPS monitor (U2417H - can sync down to 23 Hz) . Cheers

    Loading terrain data stuck at 6%

    Hi jcmygod, Well, there are M2s that are the same speed as SSD and then there are M2 that run at PCI speeds. The one I run is @ PCI speeds and it is very fast, much faster than my SSD drives (and I run 2 x 1Tb drives as a striped raid array for speed). While I haven't actually timed load speeds, my anecdotal observation is that it feels much faster and I do load ~345 GB of data plus another ~153 GB of Orbx data off the M2. I do have P3D v3 installed on the SSD drives, I'll see how long it takes to load up an Orbx location compared to P3D v4 which is located on the M2 and post back. Cheers

    Another Video Card Question

    I'm like yourself, cannot afford the huge prices of a 2080Ti series GPU which in Aust are ~$1850-$2600. I opted for a 1070Ti (while they were still available) and although, yes more power is always desirable (or maybe 2 x GPU in SLI?), I am happy with the 1070Ti but if you could pick up a 1080Ti I'd go for that over the 1070Ti, however the 2070 and 2080 would also be good options if they came at the right price (not in Aust though I'm afraid). One thing I found that complemented the 1070Ti was a monitor that could sync to 30 Hz and I chose the Dell MultiSync MHL IPS monitor (U2417H - can sync down to 23 Hz) as it's a very nice monitor with a stand that's a cut above other monitor stands, and although not 4K I find it fantastic for P3D flying with vsync smoothness. I also run a Ryzen 1700 overclocked with SMT off and the below vid shows the sort of perfomance I get with the monitor running @ 30 Hz.

    Loading terrain data stuck at 6%

    While no doubt many people will find a mittigating reason for the issue in their particular case, the actual 6% loading delay issue is due to a flaw in the code that has always existed from back in the FSX codebase What apparently happens @ the 6% mark is P3D will begin checking scenery components against library objects and it will check all components against all libraries. So for example if you have Orbx scenery you'll also have the quite large Orbx library and the checks P3D performs (performed whether needed or not) will result in hundreds of thousands of code calls dramatically slowing down the loading. You can test this in action by unselecting all library objects in the scenery config where with no libraries to check against, the loading will be much faster (but of course things will be missing due to no library objects). Note this applies to all scenery and all libraries and is nothing in particular to do with Orbx and has mostly come about due to the highly detailed sceneries being produced using custom library objects. Essentually as P3D and it's capabilites have evolved, so to have the addins we run with the result being previously minor annoyances have evolved to needing resolution. The good thing is we have Orbx to thank for getting onto LM, who have advised they will be including a fix for the issue in P3D version 4.5. So moving forward everyone wins, and the 6% loading wait point prob is resolved. In the meatime I can recommend an M2 drive (such as this one https://www.samsung.com/us/computing/memory-storage/solid-state-drives/ssd-970-pro-nvme-m2-1tb-mz-v7p1t0bw/ ) as their perfomance it truely a sixer with the loading speed improvements they provide. And it you want to read more about the issue jump on over to the the Orbx forum, login and there are various threads discussing such in the P3D support areas. Cheers
  25. Yes you won't, A2A take the position of FSX and P3D are two diferent platforms, and they also have separate purchases for Academic and Pro versions of P3D with some eyewatering price differences. But all said and done they make good planes in a class of their own and in the schema of first world problems they are worth a bit spending dosh. If you recently purchased the FSX C172 from their own shop you should have acumulated some purchase points you can offset against new purchases. I too had a few A2A planes in FSX that I'm slowing repurchasing for P3D, also if you've not come across Ant's aeroplanes before, they make a few planes of a similar type of quality to A2A for a fraction of the price, even has some demo releases. https://www.antsairplanes.com/ Cheers
