X_legio Posted October 29, 2021 Share Posted October 29, 2021 (edited) Hi there I have noticed that my rtx 3070 is not pushing to 100% during the session. Is this normal ? In other games like fs2020 it's reach the 100% . Edited October 29, 2021 by X_legio Link to comment Share on other sites More sharing options...
Bobik2002 Posted October 30, 2021 Share Posted October 30, 2021 Yes I think it's normal, dcs uses just 1 core for nearly everything, so cpu is bottlenecking. Or also it could be fps cap for vr headset if you using one, I have cv1 and if my pc can't render 90 FPS it will lock on 45 and render "fake frames".

But still he could have maxed out 1 or both cores so it's bottlenecking GPU.Send from my Poco F2 Ryzen 9 5900x | 32GB DDR4 | RTX 3090 | 32GB RAM Link to comment Share on other sites More sharing options...
sun4eg Posted October 30, 2021 Share Posted October 30, 2021 Also make sure you have HAGS turned off in windows settings. It was the case for me when I upgraded to win 11 - hags became turned on and I was experiencing 70-80% GPU util instead of ~100%. After I turned it off - it went back to ~100% gpu util. Pretty sure it was the case for win10 as well. Link to comment Share on other sites More sharing options...

X_legio Posted November 2, 2021 Author Share Posted November 2, 2021 (edited) motion reprojection is off in Open XR. The screens are from a caucasus mission with the ka50 and some enemies and friedly troups around. Edited November 2, 2021 by X_legio Link to comment Share on other sites More sharing options...
The_Nephilim Posted November 3, 2021 Share Posted November 3, 2021 it shows your reprojection ratio is at 52.6% and your dropped frames are thru the roof.. if you say it is off maybe it is not really, or something is wrong with your PC. What is the total rez you run in the G2 I see it is at 100% but what is the rez maybe it is too high.

The_Nephilim Posted November 5, 2021 Share Posted November 5, 2021 well like you said it is off in open XR but I thought SteamVR Overides that setting?? anyhow have you tried turning down the resolution of your HMD??

X_legio Posted November 5, 2021 Author Share Posted November 5, 2021 I disabled MR off everywhere, also the Motion smoothing in steam was disabled. Anyway I upgraded to a Ryzen 5 5600 and the cpu timing is going down but still no 100% GPU use.

X_legio Posted November 5, 2021 Author Share Posted November 5, 2021 I have your same settings, and in steam VR the Motion smoothing was disable, but also enable I can't go over 80 90% so exactly like you. Probably by design Link to comment Share on other sites More sharing options...

I have 80 fps on my config when playing a F18 track and just after 45 fps in quick mission / A10CII / takeoff. So I do not see why this "something" will slow down my rig only with this mission and not for another one...Did you try the same mission ?

Burt Posted November 6, 2021 Share Posted November 6, 2021 I would open up task manager/cpu while running DCS and check what’s running besides the usually DCS-Steam ect. possible an auto update of some sort.

For some mission or track replay, you may be able to use most of your PC resources and have good fps, while in another DCS mission context you won't be able to use half of your rig resources...So at first define a context that everyone can play (not a track, because you may miss some game logic eating CPU) and then compare with different user configurations to see if there is something odd. Otherwise it is like comparing apples and oranges... P8700K @4.8 GHz, 3080ti, 32 GB RAM, HP reverb Pro.

I just looked at a campaign mission with 3000 units and that's certainly different from 0 units. It's likely that op has this problem overall. Let's see.

Wali763 Posted January 9, 2022 Share Posted January 9, 2022 (edited) Hi. Testing a ReberbG1 right now. Normally Im still on Monitor/TrackIR. Plz look at my fpsVR. I have (with my low settings) good frametimes of around 15ms and also CPU frametimes around 10ms. Doing other flights I dont see often CPU-frametimes close to 20, let alone above 20. So to my understanding (CPU-frametimes lower than 22ms), there should be no reason why my actual FPS (using motion vector always active; but its same same when turned off) that low or my GPU is not maxed. Often I have 45fps, but quite often it drops to 35 with no reason I can understand. I somtimes see GPU-usage in the 90s, but much more often than that its around 60 or 70...... When on Monitor/TrackIR (and the fps-cap of 60 is off) I have consistent 98 or 99% GPU usage. Running a 5600x and a RX 6700XT at stock with 32GB Ram and all off SSDs in Win10. One interesting thing. I have not FOV-mod running; it seems ED have implemented this already to help VR. But most probably you all already know.
