Hey everyone. I am another one of the unfortunate ones experiencing an exasperating issue with my performance in VR. I got a 4080 a few weeks ago to help with VR performance. Not only does my performance seem worse than my old 3070 (was running 45fps reprojection and 0.7 PD) but no matter what I do I cannot seem to find a solution. While in DCS I experience stutters consistently. The major symptom I am seeing is frametime spikes in the framerate monitor and every spike corresponds with a slight drop in FPS for a split second which results in dropped frames or something which I can visually see as as stutter. If I am looking around in particular I can see every stutter even though the actual frame rate remains high (90fps down to maybe 82). I've dropped my settings as low as they will go and even dropped my render resolution to 30%! Same issue albeit the stutters weren't as consistent but rather more random and "harder" if that makes sense. The symptoms vary in severity based on settings of course but the end result is the same. I see a stutter or stutterS in my headset and its driving me crazy. The worst part is when I am lucky and not actively getting stutters, even with moderate settings, my frame times and frame rate are rock solid at 90fps. I don't know what else to do at this point. I think I have tried everything. I'll put a list of things that I have tried so far as well as some screenshots of the frame counter. I know I am not the only one with similar issues but I am posting here to HOPEFULLY get one piece of advice from someone with a similar system or issue that has solved this. Thanks in advance. ---------------------------------------- All the required uploads per the ED forums are attached... at the bottom. --------------------------------------- System Specs: i713700k - H150i AIO Cooler(great temps) ASUS ROG STRIX Z790-E Gaming WIFI MB 32gb Corsair Vengeance DDR5-5600 XMP1 on ROG Strix 4080 White OC Samsung 980 pro NVME Windows drive 980 Pro DCS NVME SSD 850W ASUS ROG Strix Power Supply Reverb G2 VR headset Here are some screenshots of stutters and smooth operation alike. All in DCS MT Smooth operation. Looks epic and smooth!!!!! Stutters of a more consistent nature. This is in Syria but I was getting this same symptom in all the maps. Notice in this one that the performance is awesome very stable until I get spikes. These are different than the smaller spikes above but are "harder" and more visually jarring. Changing settings didn't make too much of a difference in getting these. YES I KNOW THIS IS IN THE AO and multiplayer plays a factor. Just needed the reference photo. Again good performance most of the time then when looking around will get these single random stutters or a few here and there randomly. Here these are some really nasty random ones. Mostly when looking around. I hope this post accurately shows my symptoms with the screenshots. Here are some of the things I have tried so far. -DDU drivers -Low settings, DCS, Open XR Tools for WMR, etc. -Motion reprojection - seems to alleviate some of the performance related stutters but still get quite a lot of stuttering especially those random "hard stutters". I am not a fan of the artifacting and ghosting caused my MR. -Reinstall DCS completely. Saved games and the lot. -Frame locking - causes issues with the VR headset it doesn't like that at all. -Open XR Toolkit - Turbo mode on/off, FFR, motion reprojection -Core affinity using Process Lasso - disabling E cores and even some P cores to avoid 100% usage -Disable E cores completely in BIOS -I even reseated my GPU! -Slight overclock on GPU, MSI afterburner -forced VR and Open XR -DCS Single Thread seems to be different (???better???) in terms of stuttering but performance is overall less so I get less frames overall and that causes some micro stutters due to differing frame rates vs refresh rate of the VR headset. Thanks again for reading all the way through and for any help! dcs.log DxDiag.txt Stuters.trk

Back in December I bought a new and very expensive PC to replace my pretty decent 3070/5800 based system, in the hope and expectation of finding the best possible performance in DCS and then upgrade my VR headset to something better than my Reverb G2. The new PC has all the stuff: 4090,R7-7800x3d,6GHz RAM etc... What has followed has been three months of frustration and disappointment. While the new system has indeed perked up MSFS and IL2, the performance in DCS is barely better than my old system, possibly actually worse. The problem is stuttering. Apparently random micro-stutters and longer, prolonged stutters too. These stutters occur when playing on any map with any aircraft and seem unrelated to the complexity of the scene or the graphics settings in DCS. They occur with the game paused, and EVEN ON THE START MENU PAGE. I have spent many hours searching for a solution, both here and elsewhere on the web, and slavishly tried every suggested fix mentioned. DCS settings, PC power, Hotplug, Core affinity (maybe only for intel?), disabled antivirus, windows priorities, game mode on/off, disconnect from network, remove USB devices, rolled back to 2.8, etc etc. Nothing seems to make the slightest difference. The general performance of my system seems very good. I can get good framerates in VR with reasonably high settings even in cluttered scenarios, but the continual stutters just ruin ruin everything. I get the impression that I might be unusual in that I'm getting stuttering when paused and in the start menu, so maybe someone can suggest something new? Thanks in advance to anyone who tries to help. At the moment I feel like I'm at the end of the road with DCS. dxdiag.txt dcs.log
