Recently I have this issue where my game seems to be freezing at consistent time intervals, according to the FPS counter. For reference I am running an i9-10850k (stock), RTX3080ti, 32 gbs of ram. I have my terrain and object LOD at 165 and 110 respectively, and I have even put them lower with not much success. I also have rolling cache deleted and off, as some of the forum posts have discussed. I had thought that my computer wouldn’t have too much challenge with MSFS, so I find it odd that it seems to struggle. I am wondering if anyone else has experienced this, and if there are any more suggestions for inside or outside the sim which may help (I feel like it may be a cpu tweak somehow).
I have also attached some photos of the FPS display shown. It seems to be worse in the FENIX, and I recognize the bird is heavy on performance. In the crj, for example, there seems to be the same peaks as shown, but not to the point where it stutters my game. I understand that it is certainly tied to load, but even when I reduce both LOD, it doesn’t seem to make a noticeable difference.
I believe commenter was trying to point out that the sim / some addons are known to have issues if your Windows language settings are set to something other than English.
Do you have use recently installed external programs running along with the sim than these also can be related to stutters when sync for example simconnect.dll related
If so you can try to lower the timings of the update rate .
Those CPU spikes…do they happen regardless of aircraft, at any airport, etc.?
One time I had stutters that would happen at regular intervals (not this often). I found out it was dashost.exe talking with my smart tv over the network. I had to set up a firewall rule to prevent traffic from that IP address and dashost.exe. Not saying that’s necessarily the case here, but it gives you an idea of how wide a scope you should be looking.
Use broad strokes at first: disable all addons in community folder, disable external software running with MSFS. Close background programs one by one while the sim is running to see if one of them is the culprit. Process Lasso gives you the ability to sort programs/processes by CPU avg. utilization. If it is an external program maxing out CPU utilization that frequently, it will likely be near the top. Some people use Process Lasso to help with performance; I use it because it is better than task manager for solving this type of problem.
Use Resource Monitor to find possible network utilization corresponding with the spikes. Also look in your windows update history for recent driver updates that may have corresponded with when the problem began.
Thanks for this suggestion, it seemed to work really well! There are still consistent spikes, but they are now lower impact, meaning usually yellow or green on the fps display, which brings a smoother operation.
Thought I would update everyone on my journey figuring out the problem. I did some exploring and I thought, maybe GSX or FSUIPC are causing these issues. So, I updated them to start and now there are no longer lag spikes as shown/described! I thought I would leave an update if people are looking on google/the forums and have the same issue. Thanks to all for the suggestions!
Here is a photo taken today showing a much more consistent performance from the sim!
Yeah, it was definitely the FSUPIC. I was talking with some folks about it and they seemed to have the same trouble, with a quick update, it was fixed!
update to my system: I installed the latest version of FSUIPC and did an “sfc /scannow” command at the CMD (admin mode). It seems that the stutter has gone. I haven’t checked in VR yet, so it seems to one of those two times…. Although now my GSX is broken, but better that than the whole sim.
All relevant drivers and programs required for windows updated
all MS Store items updated
Windows updated paused
there are no background programs running, and I only use this PC for FlightSim, so no other programs are even loaded.
While there are still minor stutters in 2D mode, when going into VR the stutters are still there. Therefore, I still believe it’s something with my system and not FS, because when I use my Pimax the stutters are very prominent, even without the sim actually running (not loaded).
Finally, after conducting all the updates, without anything running (except basic windows), I just noticed the mouse curser as I move it across the screen, it also “pauses/stutters”. This is definitely a system problem at this point.
UPDATE: Removed NVidia drivers completely with DDU. HOWEVER, while in safe mode (to remove driver) there was no lag with the mouse (noticed earlier). Full clean install of Nvidia 536.99….
UPDATE2: Well that didn’t work, the stutter is back. So what doesn’t load in Safe mode??? This seems to be the only time the stutter is gone???
Did you ever fix this? I am having very similar issue with all the same fixes tried, next was DDU, but now I am wondering if that’s even worth the time now
I ended up reinstalling flight sim after reverting back to Nvidia driver 536.99. Then I reset all my nvidia settings and watched this video nd followed his directions. This really smoothed things out.
And
I hope these help. They did for me.
Oh and one more thing. Make sure your DLSS file is updated to v3.5.1. Google DLSS swapper (I don’t have the link sorry) it’s a super easy and safe way to update your DLSS file.
