WolfCat Posted October 31, 2023 Share Posted October 31, 2023 Hi Qcumber, thank you, but finding graphics settings was not the question. I have a setting for VR. The question is the bad performance that seems to be inherited form other session.

It sounds like your settings are at the edge of what your system can handle so that with a simple map and less demanding aircraft you can manage 36 fps which reprojected to 72. If I understand this right, then when you use another map with a more demanding aircraft your fps drops below 36fps and so your system cannot maintain reprojection at 72. If I have this wrong then sorry for my misunderstanding. It might be worth trying lower settings to see if you get the same problem. 5800x3d: rtx4070: 64Gb 3200: 1Tb NVME: Pico 4: Rift S: Quest Pro Link to comment Share on other sites More sharing options...

I used the pretty high graphics settings that I have for flatscreen, not my VR settings for this try (I hate that I have to reload the game when switching some settings -- and many times, from MT, it reloads the ST version, not the MT version!). Ka-50 III, Caucasus, free-flight. Was blown away how smooth that was in Godlike (well, for 72 Hz with reprojection, that is). Played around for maybe 15 minutes. Then I tried Mi-24 because previously it was a massive no-go for me in VR, having around 20 FPS and stuttering. Wanted to see how it improved. Well, it didnt. Still the stutterfest in Caucasus free flight. PROBLEM: After that, i tried Ka-50, same stutterfest, where before it was smoooooooooth. Then tried Mig-29, because they arent the resource hogs. Caucasus free flight. Smooth. Then tried ka-50 again. Stutterfest. Then Mig-29 again. Now stutterfest. Game restart did not help. This "leak" or "inheritance" is old problem, sometimes not even computer restart helps. I tried to search a lot about this. This doesnt seem to be vmemory leak, allocated ram was lower than the budget (in DCS builtin performance monitor) all the time, except for the Mi-24. QUESTIONS: Does this issue exist for others? How do i search for or report this, what keywords should i use? (I dont want to duplicate reports if someone already reported this) Why does DCS report my vRAM budget mostly at 6500MB (very rarely at 7200MB) when i have 8192 MB? I know my rig is not optimal (see below), but that should not be the issue here, as the game was running well. Turn on the "Advanced FPS" in OpenXRToolkit and check your CPU and GPU frame times. Your CPU is relatively old/slow, so I suspect there may be some CPU issues with the more CPU intensive KA-50 (compared to the F3C Mig-29) Intel i9 13900K | RTX4090 | 64 Gb DDR4 3600 CL18 | 2Tb PCIe4.0 | Varjo Aero | Pico 4 on WIFI6e | Virtual Desktop running VDXR Link to comment Share on other sites More sharing options...
zaelu Posted October 31, 2023 Share Posted October 31, 2023 (edited) A small-big discovery I made today... After having HAGS OFF since like... forever... because it was known to be a performance problem etc I turned it ON because I saw in a youtube (vrsim guy iirc) that sometimes it makes the micro-stutters disappear and... it did. From this: null to this (the second image is a capture from a video recording so is way worse quality wise but the graph is visible) Also I tested the "Low Latency" Settings in nv control panel and with it ON or set to ULTRA the "feel" was not as smooth as with it on OFF, However it was the only thing that Pushed the graph to finally show "GPU BOUND" instead of CPU BOUND" as seen in 3rd picture where you can see it's now green gpu bound. However, I prefer it on OFF. Now if only my GPU would have been a 5080.... PS Oh and the "pre-render 3 frames in VR" setting in nvcp also did nothing, added a very slight increase in latency but no improvements. So I'll keep it on 1 frame (default).

As I can see from screenshot's you are using WiFi 5. From my experience with Pico 4 most of the problem coming from too high Bitrate for connection speed. If you are using WiFi where speed fluctuating Reduce Bitrate or use Automatic bitrate. Automatic bitrate will use this 400Mbps as cap bitrate when the connection speed can handle it. When speed is drooping automatically Bitrate according to Speed to keep smooth transfer of picture. Otherwise you should find sweet spot for your Bitrate and connection speed manually. Sometime stuttering is caused not by GPU or CPU but because not balanced Bitrate/connection speed. Link to comment Share on other sites More sharing options...

Danzig Posted November 2, 2023 Share Posted November 2, 2023 Ticking this gave me a smoother experience. before the tomcat cockpit gave me some jiggerish 56 fps. now 72 fps just by klicking this box. Maybe worth a try. Link to comment Share on other sites More sharing options...

I keep trying but I get really bad black borders when moving my head at anything less than about 60 fps, even with reprojection. I find that aiming for 72 fps without SSW is the best option for me. 3 5800x3d: rtx4070: 64Gb 3200: 1Tb NVME: Pico 4: Rift S: Quest Pro Link to comment Share on other sites More sharing options...
RealDCSpilot Posted November 7, 2023 Share Posted November 7, 2023 (edited) VDXR integrated in Virtual Desktop is officially released now! You can now run DCS with the Pico 4 without SteamVR but in native OpenXR. This should also come with a little performance increase for everyone. Simply choose VDXR in the options of VD streamer on desktop and then launch the DCS.exe (multi-threading version).

MIghtymoo Posted November 10, 2023 Share Posted November 10, 2023 I have had issues running Virtual Desktop in VDXR mode without severe stuttering. Had to use SteamVR.

Qcumber Posted November 17, 2023 Share Posted November 17, 2023 I have noticed that VD SSW is working a lot better since the DCS 2.9 update. There has also been an update to VD (1.29.9) which improves SSW for Q headsets. The Devs say that there has been no change to Pico though. Has anyone else noticed an improvement? The changes I am seeing are: 1) Everything is a perfectly smooth at 45/90 and surprisingly smooth at below 45. Much better than how it used to be. 2) The black mask effect when moving your head is a lot less noticeable. 3) The odd shimmering when rolling the plane is still there but maybe a bit less noticeable. I should stress this is different to the regular ghosting of fast moving objects and does not occur with oculus ASW. Overall this is a much better experience and I can now run at high and maxed out settings and only drop below 45 above big cities like Cairo and London. Even then it's a good experience, especially as I can set the landscape range to Extreme. 1 5800x3d: rtx4070: 64Gb 3200: 1Tb NVME: Pico 4: Rift S: Quest Pro Link to comment Share on other sites More sharing options...

I should stress this is different to the regular ghosting of fast moving objects and does not occur with oculus ASW. I wonder if the same effect (odd shimmering/ghosting when rolling the plane on distant objects) is also there on Q2/Q3/Q-Pro headsets (it's not there on a Rift-S but that has a Display Port) because it's the main reason why i returned the Pico 4.

apelsin44ek Posted December 3, 2023 Share Posted December 3, 2023 Is it possible to have acceptable fps (at least 30) w/o VD? Right now I have 1-3 fps in single player on A-10CII. Currently I have RTX 3070 8Gb, 16 Gb RAM and AMD Ryzen 7 5800X. I have no idea what is happening, w/o VR I have never ask any questions about fps, it is just high enough in all situations. But in VR it is not possible to play, unless I put resolution to the lowest settings possible when I could not read any words in the cockpit. P.S. Buying VD not possible due lack of the access to the Pico store. Link to comment Share on other sites More sharing options...
Vector1 Posted December 3, 2023 Share Posted December 3, 2023 Hi you can access Pico store by changing country in your Pico account, I'm in Australia , I set my Pico account to United Kingdom , don't have access in Australia yet , could buy Virtual Desktop this way, over a year ago , also Virtual Desktop has VDXR setting that allows you to bypass SteamVR.
