I started this topic to track and discuss challenges with getting the best performance out of the system. I usually test each setting a couple of times. 27-1-2025 Nvidia 571.96 DLSS 4.0 Installed the new drivers. 25-1-2025 Adjusted GPU Overclock Increased CPU PBO Scalar and reduced some of the GPU overclock to further increase fps and frametimes. Time will tell if it also stays stable on the MP-servers. 18-1-2025 Clean W10 Complete reinstall of W10 returned another 5fps and better frametimes. Over the years the system got bloated with all sorts of traces from old hardware that I upgraded (2x GPU and CPU) and software that I tried and not fully removed. The system is snappy and clean again! I considered W11, but there are too many bad stories out there, no clear advantage for AMD and GUI modifications with taskbar etc W10 is easier. The only thing I still notice is that it seems that when I hit the FPS limit some sort of trouble in FPS and frametimes appears. When I stay a bit below 90, like 88fps, it is more stable. 27-12-2024 Current Overclock settings 64GB ----- EXPO: ON (timings default as stated on the DIMMS) 9800X3D ----- Turbo Game Mode: ON PBO: +200 Curve Optimizer: -20, FCLK Infinity Fabric: 2200 UCLK DIV1 Mode: UCLK=MEMCLK, SCALAR 10X 4090 ----- Core Voltage: +100 Core Clock: +120Mhz Memory Clock: +900Mhz, Fan: Power Limit 133%, Temp Limit 84. This GPU overclock is stable and gives me 4-5 extra FPS, even when i am CPU bound. My setup Windows 10 - latest version - Windows 11 will not happen until I will get serious latency advantages. Motherboard: ROG STRIX X870E-E Gaming WIFI Systemboard VR Headset: Varjo Aero SSD for DCS and Windows, separated DCS Settings Most are set to the max. SSS, Secondary Shadows, SSAO, SSLR are disabled; they do not bring much visually. Visibility Range Extreme. I have Visible Range set to High. Increasing this further is not bringing much visual improvement and really takes away performance. MSAA Mask Size 0.42 is my sweetspot. Testing Setup and approach My Windows has been heavily tweaked and optimized and I am currently still running the same Windows I started with 5 years ago. I upgraded my systemboard, CPU and GPU a couple of times but did not reinstall Windows. I think at certain moments in the past I even went too far with tweaking and should have dialed back and better register what I was doing. So a clean install will be somewhere in the near future because I am certain I have left quite some performance on the table. For the basic quick test of setting adjustments or hardware/software updates I start a the default A-10C mission Runway Startup on the Marianas Map. I use Marianas because this mission is quite demanding and quite stable almost from the start with AI not doing much. I let it run a couple of times for 20 seconds and track the performance with CapFrameX to calculate the average FPS, 1% and 0.2% lows of the runs. Many other missions give me 90FPS, so adjusting settings with such missions will not give me noticeable visible differences. If I want to visually see the performance I open up the the FPS overlay inside DCS. I sometimes also open up the new XRFrameTools application to visualize my frametimes. Once a setting looks pretty okay I log into our Wing's Multiplayer server, startup OBS recording and give it a spin to see how it goes. I usually get 90FPS flat in this setup, while running OBS recording. Testing log From now on I will start adding my complete testing logs to this main posting. Where relevant I will add charts to visualize the difference between certain options. Certain tests were eye-openers. It was/is a dreadful process going through all the settings and quite a few settings were insignificant in my case. Frame Times, average FPS, 1% and 0.2% Lows My main goal is to find the ones that will bring more stability (reduction of intrusive stutters) and performance (increase of FPS/frametimes). Sometimes it is like searching for a needle in a haystack. Seeing the settings that made a difference might bring quick wins to others as well. Overall the average FPS is not improving that much by all the tweaking, it is easy though to screw up your system and reduce FPS. But once the FPS are pretty decent it is hard to get substantial improvements. My biggest wins are with the 1% and 0.2% lows, reducing these give a much better overall experience than to have 1-2 more average FPS. The overall FPS can be high, but when you have a few microstutters here and there it is very annoying and for me breaks the immersion in VR. Caution Please be careful, not all what works for me might work for you. Do everything at your own risk. I had some crashes, especially with the overclocking, so always make backups and restore points. I also don't have my overclock software start automatically anymore when tweaking, because that also caused an issue once causing me to keep rebooting into a crashing configuration. null null null

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
