  1. After a day playing around with settings (a couple hours' worth of actual sim time) I've discovered something about the stuttering that's occurring for people, regardless of their specs. I want to make clear that this is just MY experience, and I'm not knowledgeable enough about the way the sim or the CPU and GPU work to suggest how applicable this might be, in general. But this is working for me right now. First, here's what I'm playing on: i9 9900, Geforce RTX 2080ti, 64 GB DDR. I play on a widescreen, 3440x1440 resolution. I'm finding that the sim runs very clean for me, almost regardless of settings. I have nearly everything cranked up to max, with the exception of a few sliders (water and reflections and shadows) set to high instead of ultra. But yes - I was getting stutters when I cranked it up this morning. Periodic ones, sometimes, and other times consistent ones. Just little hitches where the sim seemed to be "thinking" about something rather than running. So I started, one by one, altering the settings, and none of them seemed to make a difference. But then, really just on a hunch, I turned off texture supersampling, which is described in the sim as controlling fine detail like "road marks." I wasn't sure what that meant, but when I zeroed it out - voila, not a single stutter. The cost to visual quality, so far as I've been able to tell, is confined to runway markings - numbers and lines that don't appear as crisp as they did before. (I had this set to 8x8). I'm not seeing anything different, anyplace else. I tested this out just now on a short-ish flight from Sacramento Executive (SAC) to Tahoe Regional (TVL). I used the TBM. Short hop across the mountains, and down into the lake valley, one of my favorites for VFR. Not a single stutter in the entire flight. There were two hitches I noticed, when the sim was clearly loading some piece of terrain... but again, just twice. Otherwise, perfectly smooth flight, with the settings nearly at max. I don't know much about supersampling, other than what I've said here. Is this mayb a glitch with the setting, or is it a setting that, when jacked up, somehow interrupts the processing of the sim? I don't know. But I wanted to share here, in the hope that there's something in this post that helps decipher solutions. Would love to hear what others are finding. As an aside, I'm pretty blown away by the sim so far. Unbelievable detail, really nice, nuanced flight model and stunning weather effects. It is a GIANT leap forward in flightsimming, in my opinion. Yes, there are many many areas that need or could use improvement, and some glitches that clearly caught Microsoft by surprise, as they weren't things that seemed to report out of the beta. (For reference, my first flight simulator was Flight Simulator 4.0, in 1989, and I've recently been playing X-plane and P3D, both of which I consider outstanding sims. This one, though, on day one, is clearly the birth of another generation.)
  2. Why do I get 20-30 fps in cruise and it's really stuttering. On ground I can get 30-50fps depending on scenery and it's not stuttering. Using Prepar3D V3.4.22.19868. Maybe overclocking my CPU had to to something with it, because before that it didn't stutter that bad in cruise. Specs: Gigabyte GTX 770 2GB, i7 4790K @4.4ghz, 16GB DDR3 RAM, Asus Maximus VII Ranger motherboard, CM Hyper 212 Evo CPU cooler, 500GB Crucial MX200 SSD (this is where P3D and addons are installed), WD Black 1TB 7200RPM HDD, Corsair CX750 750W PSU, Windows 10 Home 64bit
  3. Hello people, I have been dealing with this problem for a very very long time. What my problem is, is basically that everytime I just pan around with a view in FSX (no matter which view), it looks as if I have some sort of cuts or cracks in the screen. I have had this problem for the time since I played FS, but since I recently bought a new computer, and I got a new monitor with it, I only started to really see it more clearly. I have a link to a YouTube video, where you can see what kind of issue I have: https://youtu.be/wSrObxJaJD8?t=2m33s Now, the subject of the video is irrelevant, but look closely to the screen, and you can see quite some lag stutters, with parts of the screen not bordering each other correctly. This is the problem I have been dealing with for a long time, and I would like to ask the FS community of how it might be solved. Regards, Raphaël.

  5. After reading the "umpteen" threads on micro-stutters, I wanted to see if I could improve on my own. I just discovered my three 27" have the capability to run at 30Hz. so I have been testing the 30/30 scenario (30FPS at 30Hz), and I must say it is about as smooth as I think I can get P3D at this time with my set up. Question is do you guys who run it at 30, do you revert back to 60Hz when you are done flying? Any residual effects that you have noticed running your displays at 30Hz 24/7? Clutch
  6. Hi, I'm really thinking of buying a GTX 1080 or a GTX 1080ti then a 4K monitor. My GTX 1060 6GB is good and can handle even the PMDG 777 at Gatwick with 25fps! However, I get stutters. I have determined that my GTX 1060 6GB is the bottleneck causing these stutters. I can remove these an get a fluid experience by turning on V-sync and triple buffering, leaving fps on unlimed. But, I have to be achieving 60fps (because of my 60Hz monitor) meaning I can only really be smooth with no stutters at cruise. I know you can set to 1/2 refresh rate in Nvidia Inspector and I have tried that. But again it's only smooth if your PC can continuously maintain 30fps, which mine can't. It's very unstable, one minute I'm 40fps then in 16!. So if I get a GTX 1080 would the PC be able to maintain a steady 30fps so I could put 1/2 refresh rate in NI with V-sync on? If and only if I'm still getting stutters, I would buy a 4K monitor and set the refresh rate to 30Hz and do the trick which removes stutters. There is one more way I thought I could remove the stutters. For it to work I would have to maintain 60fps all the time, what kind of immense hardware would I need to provide this? I run Orbx, PMDG, addon scenery so It would have to be beefy! Do you think a GTX 1080ti would cut it? My Pc: i5 8600K @4.7Ghz GTX 1060 6GB upgrading to a GTX 1080. 8GB of RAM (I am switching to 16GB @3000Mhz in March) P3D on a 2TB HHD BenQ GW2270 monitor @60Hz P3D V4 config=https://www.dropbox.com/s/na1dumhjzw5sooo/Prepar3D.cfg?dl=0 Thanks, Ollie. 4K Monitor trick: )
  7. Hi, I am experiencing jumpy/stuttering camera movements. They appear to hit a regular "clock tick" intervals. So every 1 second of so, the camera appears to stop and then immediately start moving again. This happens when using the middle mouse look, and when switching between presets. Has anyone else had an issue similar to this? I searched the forum but couldn't find anything about this kind of problem. I do not think it is FPS related as it happens at all performance levels. I am using the PMDG 737 in P3D v4 Thanks in advance for any help that can be offered.
  8. Hi there, ezdock version 1.18 is very choppy and not smooth in p3d 3.4. Choppy meaning it is lagging behind while the game itself is moving at 50 fps. ASN has no affect with it sand I've tried anti virus off. It only gets smooth at 60 fps and above, anything under it chops and lags. Should I upgrade to V2? Anybody know how to fix? Dillon L
  9. Hi all, first of all I would like to say thank you to the whole PMDG team for this awesome product. I started simming with the FS95 more than 20 years ago and since the very first day I was hoping that one day a 747-400 simulation like the one you now created would become possible... So now that "one day" has come... I just cant believe how good it is in every aspect (it looks great, it sounds great, it feels great, documentation is outstanding etc...) Second I would like to report a little issue I found at least on my system: I observed that I got a systematic stutter (fps drop to 7) a few seconds after liftoff at about 30 feet radio altitude. This stutter did always happen when I did a complete preflight. However sometimes when I just went flying without doing all preflight steps it wouldnt occur. This happened regardless of scenery (default and addon), weather and everything else apart from the airplane (but on all models / liveries that I tested) After several days of testing I could finally isolate the problem: And its surprisingly (at least for me) related to the nav and strobe lights.Whenever I take off leaving both lights off, the stutter wont occur, whenever I take off with both lights on it will. I subsequently also found out that this stutter can be triggered even on the ground by switching both lights on and then back to off. As soon as I switch the second one to off, fps will drop to 7...... Additionally I now observed several youtube videos from other simmers and it seems like it might be happening there as well (for exampel here at 1:14 - 1:15) Can someone else verify that? While its not a problem for me any longer because I just can leave those lights off it might be interesting to look into it.... thanks in advance and regards Marinus Gerst
  10. Back in the days of FS98 - 20 years ago - the sim would stutter as you flew over the Prime Meridian in London. With all the advances in flight sim since then I'm really surprised the problem is still there in P3D. I noticed it when slewing across London when testing performance in P3D v3.4. After slewing up to 1500ft at Rwy 28 at London City airport I increased speed to 240kts and started to move towards Canary Wharf. As I approached the buildings P3D stuttered really badly for a couple of seconds. I wondered what could be causing it but finally the penny dropped. The aircraft is crossing the Prime Meridian. I remember FS98 (and maybe even earlier versions) having this problem but I would have thought it would have been solved by now. Looks like the same basic engine is driving P3D as drove FS98 and probably all versions since. It won't happen just in London of course but anywhere where you cross from one hemisphere to the other. Anyone else noticed this?
  11. Hey guys, I have been doing a lot of research online and digging up old threads but our situation and hardware setup is rather unique that I need to turn to the community to get some more outside the box ideas flowing. FSX stutters quit bad even though achieving a very acceptable framerate on the ground FSDT KLAX approx 30 on the ground. I made the PC: Intel i7 3790K 4.40Ghz, 8GB DDR3 Ram, ASUS P8Z77-V, EVGA 670Gtx, 500gb Samsung SSD, Corsair H100. That pc runs a triple head to go, VGA to three displays running at 1280X1024 each, giving a final resolution of 3840X3072. Even though I get 30fps on the ground when taxiing turning, turning in flight, usually short final there are several hiccups to near slideshow effect then it will resume to normal fps again. I have tried a lot of combos with NVI. BP=0, SGSS, 8XSQ, 8XS, no transparency AA, Vsync 1/2, Vsync off, FPS 30 in NVI and unlimited in the sim. Graphics drivers are up to date and current. I am not sure what else to check or do. REX and Texture max load have been decreased down to 1024 REX and 2048 fsx.cfg. I also deleted the shader cache, as well as rebuild a fresh fsx.cfg and re add the necessary tweaks. HIGHMEMFIX, Disable preload, WideViewaspect true, TBM 80, TML 4096 or 2048, nothing else other than that. BP causing artifacting so that's why I remove it. The visuals show just the outside, no 2d panels or VC. So I am really struggling to figure out why this PC is having a hard time with a relatively easy load and low low levels of AA.
  12. Hi guys, So I'm wondering if someone can help me with this as it's rather frustrating with my PC which is more than capable of running P3D on medium to high settings. The FPS inside the cockpit of the PMDG 777 is around 35-40 FPS which is great, however when it comes to panning around with the camera it seems very "jerky" and stuttery which puts me off completely. It doesn't happen all the time, but mainly whilst on the ground. The only tweak for my P3D cfg that has helped so far is Fiber Frame Time Fraction 0.01. I have tried locking the FPS at 30 which makes the issue a thousand times worse, and only locking at 60 or unlimited makes it slightly better. I've tried enabling and disabling vsync and triple buffering which has very little (if any) effect. I have also tried enabling/disabling vsync, triple buffering, Hyperthreading and Intel Speedstep, all of which make very little (if any) difference at all... How can I get rid of this annoying stutter and get smooth panning inside the cockpit? The problem is completely gone when panning around outside the aircraft. Specs: Intel Core i7 4790k overclocked to 4.4GhZ NVIDIA GeForce GTX 980 16GB Corsair Vengeance RAM Windows 10 pro 64 bit Addons: Active Sky Next GSX Ground Services PMDG 777-200 (Base Pack) FTX Global REX 4 with Soft Clouds Any suggestions would be great guys! -Yorkie
  13. Hi All I've watched countless "settings" type videos and posts to try to optimize P3D V4, however no matter what I try, can't seem to get rid of micro-stutters I've even tried to put all sliders to the left and increase them one by one to find the underlying issue, but it's still there. The FPS counter can't seem to hold steady as it moves from 10 to 40 and back all the time. I have a G-SYNC monitor and have tried both V-SYNC on/off and locking the FPS to 30 but it has no effect. What I also find surprising is that moving all the sliders to the right doesn't have a massive impact on the max FPS I can get. My specs are below Intel i7 - 6700K @ 4.00 GHz 16.0 GB RAM GTX 980 Any ideas on what I could do to help make the FPS smoother? Is there something in Nvidia Inspector perhaps? Many thanks
  14. Hi guys, For a couple of weeks now I have noticed that the simulator started to stutter; micro stutters (some sort of a quick back and forward movement) and somehow it is related with the audio (I guess). If I am listening to some music or YouTube videos while running FSX, they will audio-sttuter as well. First I thought it was caused by Active Sky Next, but after making a couple of tests I discovered that ASN was not the problem, so I updated the drivers of the graphics card, disabled the antivirus, lowered the sim to the minimum settings and modified the FSX.cfg (Affinity Mask, Bufferpools, etc.) without success. After testing various configurations with Nvidia Inspector without success I decided to restore the PC to factory state. When I finished installing the simulator according to Nick's Bible, to my surprise, the problem was still there. I'm truly desperate as I don't know what else to do. The computer is fairly new (December) and never had a problem... until now. I'm posting my problem here hoping someone can help me or guide me a bit on this issue. PC specs. are the following. · FSX (SP2). · W7 Professional (64 bit). · Nvidia GeForce GTX 760 Ti OEM · i7-4790 @ 3.60 ·16 GB RAM. Thanks in advance, Andrés.
