Hi all,

 

Firstly, let me say I am not a frame-rate chaser. I am happy with 30fps, and happier with smooth. For the last year I have been running FSX on Windows 8 with a GTX580 with no more tweaking and 30fps pretty much all over the shop.

 

Then I went and bought a GTX Titan. I did this for two reasons: firstly, I am a big P3d fan and it likes VRAM; secondly, I wanted to see if it made a difference in FSX. Boy does it make a difference. Until last night.

 

Anyway, when I bought it, and as it was about a year and a half since I reinstalled FSX, I did a total removal and reinstall. Everything. Airports, sceneries and finally FSX itself. Three days later (really - only installing in the evenings) I was back. I have only installed all of my ORBX and FSDT stuff and RealAir and Carenado planes so far, so a pretty vanilla install.

 

When I first fired it up, it was amazing. It wasn't the FPS, it was the smoothness of everything. A revelation (*cough - it should be for the $)

 

I decided to run in DX10 as I figured it would tax the GPU a little more and perhaps allow for higher FPS (I know I said I wasn't an FPS chaser...) I am using Steve's fixer.

 

All works fine. However, I now seem to have a marked stuttering problem in both DX9 and DX10. My frames are dropping to 15 (I use 1/2 rr in NVI) and it is struggling. Taking all sliders to 0 makes no difference so it seems to be something else.

 

It is the same in P3d. It is like a stutter a frame, thereby dropping the fr to 15.

 

It seems better with stock planes, but I am flying into CYVR atm, around Puget in the Carenado B200 and it is awful. Worse than my old GTX580 LOL

 

Any ideas? I am using the latest R331 NVIDIA drivers. I have seen some stuff somewhere saying VSync is broken in that release. Can anyone conform this? Should I turn off Vsync and live with tearing until my 120Hz monitor arrives?

 

I'm a bit stumped as it hasn't coincided with any particular tweak bar installing DX10 and using that (with its own NVI profile obvs)

 

Many thanks in advance

I heard that if you turn up your settings, the Titan will start to work harder and actually preforms better. You probably know way more than I do on all of this but perhaps that might actually work. Although you did say you were flying at YVR and everything, so I'm kind of stumped as well. Have you played around with inspector settings?

Hi,

 

Thanks for the reply.

 

Well, my sliders are maxed. I only lowered them to see if it made a difference and it doesn't seem to really, well, it does a bit but not what you'd expect. It makes no difference where they are, or if I use DX9 or DX10 it seems.

 

I am beginning to suspect the drivers and Vsync. I have removed the ForceVsync lines from my cfg

 

I've tried it with no NVI settings, Pauls recommended ones, the ones I saw at Word Not Allowed's site, a few variations of my own, nothing seems to make much difference. I am still experimenting..

Ok, so I just deleted my cfg file and with only HIGHMEMFIX=1 in the newly generated one I am seeing 8-11FPS taking off from CYVR in a Beech Duke Turbine.

 

Something not right here...

Sorry I cannot answer you but I have as well stuttering problem. With good framerates 29.9 mostly I have small stuuters which are occuring all the time. I tried a lot for DX10 cause I was quite happy with DX9. But in DX10 I get better frames. I tried with REJECTED THRESHOLS BUFFER, FIBER FRAME, DIV AA, NVIDIA INSPECTOR.... I disable UT, Flight Keeper, COUATL, FSINN, OPUS but still stutters. Maybe it is caused by the DX10 option. I do not know where to search now.

WIN7 64bit, 4.9GHZ, Nvidia GTX580 with the latest driver. (Maybe I should try with an older driver, a driver which was perfect for DX9) Any help is very appreciated.

Regards Tom

Should be no stuttering with your system, Tom, but not knowing what monitor(s) you are using makes it difficult to give you a definitive answer..

 

Please put your system specs and cpu speed in your profile, so that it appears under your Avatar. Then - copy and rename your fsx.cfg to "Tom_fsx.txt", and attach it to a reply, using the "More Reply Options" (bottom-right). Follow that by posting a screenshot of your Inspector settings, please!

 

Thanks,

Nice system!  Try these changes, Tom - the cfg is very good, but your TBM is too low.

Thnx Paul,
I changed the cfg like you adviced
Usepools 1
RejectThreshold 524288
Poolsize 10485760

Image_Complexity 4
TBM 120
FFTF 0.12 is this not very low? How does this work with ORBX?

Unfortunately it is more or less the same, maybe slightly better. But for sure not significant.
I tested with only one monitor same result, I use clone monitors to use the touchscreen for the instruments where I scroll via Opus. As I said I disabled all addon soft - opus, flightkeeper, fsinn, UT, couatl, goflight bridge. I do not think that I have to try with disabled fsuipc :-)

Kind Regards Tom

Try defrag and application controlled VSYNC in the NI for a while. Fullscreen or windowed?

Hi Michael, no defrag on SSDs. VSYNC will try. Fullscreen and Windowed (on FSLab concorde) mostly Fullscreen.

Intern VSYNC does not help.

Highmemfix=1 is not a tweak. It is a fix that Microsoft developers forgot to add in SP2/Acceleration. FSDT CYVR is a known memory hog if not properly configured. I don't know if you have FSDT's version installed or not but that's the case. I get decent FPS with my system but then I don't have all of my sliders maxed out and have my settings set as per the AVSIM FSX Configuration Guide (link under the Content Tab). It's somewhat nasty with Orbx/FTX stuff installed too. Can't you find a nice airport in Nebraska or something to take off from? LOL! Just kidding. I can replicate stuttering 100% of the time if I have no page file on the drives where the scenery is located. The page file must be set to System Managed Size. There is no magic tweak that will fix stuttering.

 

Best regards,

Does this mean that Pouls recommendation is not up to date putting a pagefile OF FSX installations DRIVE :huh: ? Hmm i dont get stutter with Pouls recommendations btw.

Hey Paul, it's my system (I was OP) and my specs are in my sig :D

 

I have cured it but by using 17th century remedy. I amputated Windows 8. Totally rebuilt the PC. Re-installed FSX and used the Guide and NickN's new bible over at Flight1 to create the proper platform.

 

I re-installed FSX and only certain add-ons in a very specific order. I am half way through again, but can say that, as of today, I have no stuttering. I am still using DX9 so far. When I am totally done, I may go back to DX10 as it seemed to deal with newer sceneries better.

Hey Jim. I am aware of the HIGHMEM omission. It is the only entry I am using now, until my system is totally built and finished. I was and have been doing a lot of system-related things wrongly for the last few installs, and am now treating my FSX rig as a "single-use" device, and as such, won't be doing anything else with it.

 

I am running the FSDT CYVR with HD shadows, but with 6Gb of VRAM and 16Gb or RAM and few extra add-ons, I shouldn't be seeing any problems. My autogen slider is now at 75% and I installed the "mid" shadows on the FSDT and it is now much, much better. I shall report back when I invoke my NVI image settings, as I haven't even set that up yet this time.

 

I have now rebuilt my FSX rig twice in as many weeks. I am getting bored with it LOL

 

 

Have you tired internally locking your frames to 33? Have a look at this thread: http://forum.avsim.n...ce-faq-from-lm/

 

 

 

I no longer use any frame rate limiters. They are a placebo with my system, I think. I should not need them with 4.7Ghz and a Titan! I have tried with and without; internal and external. I get by far the best results with NO limiters anywhere and FSX at unlimited.

Good to hear i am not the only one with better performance setting FPS to unlimited. We have simular setup.

This is a serious mistake many have when using FSX. They have a huge page file and have a lot of RAM but it means almost nothing to FSX or FSX addons as they are all 32-bit apps operating in a 64-bit environment. What is important is Virtual Address Space (VAS) and, when that gets low during a FSX session, you might see some stuttering as FSX is trying to find enough space to run FSX. VAS is not the same thing as the VRAM (page swap file) that you can adjust in your system settings. A large page file or virtual memory swap file does not protect anyone from the 4GB VAS limit. This is the reason I strongly recommend watching your settings and to not set anything up too high. You do not have the holy grail of computer systems (even though you do have a nice system). If you read the AVSIM FSX Configuration Guide there are different settings for different systems. AVSIM used the guidance of many developers and one was Orbx/FTX guidance. If you have a fast system (as you do) you can move your sliders up but not all to max, especially Autogen.

 

Hope this helps.

Hi Jim,

 

Thanks for the reply.

 

When I said VRAM, I meant Video RAM. My grafx card has 6Gb of VRAM. My page file is set to 3072/3072 and I am aware of the 3072Gb limit with 32-bit applications; I run an IT company :) I have 16Gb as I did a lot if video editing with this machine. I don't anymore,so I shall remove half of it. I have been tweaking FSX and my system for what seems like years now (actually, it IS years LOL) and am well aware of the 32-bit wall.

 

My point was, with only two or three add-ons installed, and only flying over one of them, FSDT CYVR, with 2048mb shadows enabled, and a 6Gb grafx card, my VAS shouldn't be so low (and isn't according to Procmon) that it causes stutters as bad as I was seeing. This was before installing any ORBX sceneries; simply FSDT CYVR and a RealAir Duke Turbine on a fresh install of FSX.

 

Anyway, as I said; I think I have it licked now. I totally rebuilt my system, which is drastic, I know, but it needed it and it has made a difference.

 

 

You do not have the holy grail of computer systems

 

 

LOL - what IS the Holy Grail these days? Dual Xeons? I am running at between 4.6 and 4.7 (soon to be upgraded to a 4930K Extreme) That should be good enough to run at 25FPS, surely?

 

Again, thanks for your time,  :)

Many people do not realize how important it is to defrag after any install.  You say you have just rebuilt your system, so a defrag after each install of any program will help the files be defragmented and help keep the disc from hunting which causes stuttering.

 

Always defrag after any change to your file system..

Of course. I have the Haswell 4770K and your 3930K is more efficient than mine - http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-3930K+%40+3.20GHz so you should have decent fps. My fps are set to unlimited (I use the settings in the AVSIM FSX Configuration Guide) and get between 32 and 60 most of the time. If I'm at a FSDT airport like KORD in heavy weather (using a commercial weather program), with the PMDG 777 running, I'll be fighting to stay in the 20's until I can finally take off. But, IMHO, anything over 15 fps is great. Anything below that is ugly and removes the fun out of flight simming. If you were around when FSX first came out in late 2006, we were fighting to stay above 15 fps and anything near 30 fps was awesome! With your system you will probably get more enjoyment out of P3DV2 as that engine has been tweaked and updated. FSX is still operating with old programming and calling textures and rendering are less efficient. However, if you keep your settings at a modest level, you'll enjoy the product much better.

As said earlier by Jim the VAS is a killer - It took me some time to realise this but tweaking FSX for years do give some experience.

 

And examplecould be EGLL or CYVR for that matter. Try take you PMDG 777 or simular heavies out for a VFR in London with 75% settings and FTX England perhaps and some traffic as well and then some HD2048 textures.

 

I would get about 25-30fps relativ smooth in the T7 on this short "trip" and a OOM in DX10 on approach to EGHI Southampton but if we forget the last part :P   - try do the same flight from a 4-600miles distance airport and you will end up with a stutter and slideshow properly because the VAS is full. This is so frustrating after 2hours so thats why i save my flights before descent and then load up FSX again freeing som VAS.

Nooooo.....  don't put the swap file on the FSX drive, Michael.  You've mis-read the post!

 

1). Windows needs a small space - for start files and ctd's, basically, and this should be a minimum of about 200MB, and so mine sits at 450MB at this moment. Here's a couple of pics with different sizing and location.

2). Don't put a swap file on an SSD.

3). Don't put a swap file on the flight sim drive.

4). This means that the swap file is going on a third physical drive (not a partitioned drive), and it must be a mechanical drive.

 

5). If there is no third drive - then the swap file should go on the operating system's drive.

 

6). Each swap file size should be "Custom", with the same figure in both boxes, as this will prevent fragmentation occurring.

 

7). Whereas this is subject to many differing experiences and opinions, the swap file should be at least 1GB, but doesn't need to be bigger than 2GB. This is because the possibility exists that one might encounter a circumstance where an application, or the OS will suddenly need that space, and if it's not there - one could end up rebuilding the whole system.

 

Jim and I both differ in a number of technical areas, Jim preferring to let Windows manage the file. 

 

I hope this clears some mud. If someone requires my in-depth reasoning for "Custom" please feel free to pm me.

 

All the Best,

I definitely do not want to disagree with my friend Paul.  I got my info regarding SSD's from Microsoft Technet -

 

"Pagefile is exactly the kind of thing you want on your SSD. Taking it off negates one of the biggest advantages of owning one, since most of the stuff in the pagefile is small reads/writes at which SSD's excel. If you wanna limit its size, fine, but don't disable it or move it to another drive.http://social.technet.microsoft.com/Forums/windows/en-US/af427b34-7d1a-4a5f-81fc-855f66ae5a6d/windows-7-ssd-pagefiling-and-raid0.

 

I recently reinstalled Windows 7 and FSX and all my addons as I built my present system.  I had everything installed and KIAD was just released.  I had a system managed size page file on my SSD where my OS and FSX resides.  Flying out of KIAD I suddenly saw strange stutters.  Strange as they were each about a second long (and that's a long time in the computing world). It was unbearable!  I could not figure out what was wrong.  I checked my page file settings and saw that I only had a page file on my SSD.  I did not on my two mechanical HDD's that housed my addon scenery.  I enabled a system managed size page file for the other two drives, ran fsx, and the stutters were completely gone.  So that was my experience and why I always recommend a system manged size on all disk drives.  It might be wrong as Paul suggests but at least it is working great for me and I'm just passing it on for what it's worth.

 

Best regards,

This is a great thread as I have been experiencing the same issues. And my system should have no issues running FSX.  I am going to try these suggestions out and let you know what happens. 

 

Thanks,
