Nvidia settings for Reverb G2

[Youtch]

I just came accross this video, regarding new NVIDIA driver.

 

I know that it is mostly for MSFS but I could not help wandering if any of this might actually improve VR experience in IL2 as well.

 

Specially regarding the setting of max frame rate and Vrtual Reality pre-rendered frame.

I set my max framerate for the Vive Pro 2 at 45 in Nvidia Control Panel.

Hi dburne, are you using any motion smoothing? With my g2 I am not using motion smoothing. Just dialed in all settings to give me 90 fps pretty consistently. What would happen if I set this fps limit in nvidia to say 80 fps considering the g2 is either 60 or 90 hz. Just curious.

No I have tried it with and without and while Motion Smoothing is much better in VP2 now I still prefer it off.

I do not know the answer to your question, you might try it and see. I am of the thought it should be set to either 45 or 90.

I know in my Vive Pro 2 if things get really busy ( like on supercarrier in DCS) sometimes with it set to 45 fps my fps will drop down to 30 fps briefly. But as long as it gets 45 fps the experience is pretty good.

Thanks for that dburne. I may set it to a 45 fps limit just to see what happens. I’d like to turn up the resolution but can’t get it any higher than I have it now without dropping below 90 fps too often. It will be interesting to see if a 45 fps limit with a higher resolution works better than what I’m doing now. I did try running the headset at 60 hz but didn’t like it at all. It ran great at around 90% Steamvr resolution per eye but a strobe light effect was very obvious to me.

MSFS has absolutely abhorrent optimisation for VR. If I just run on my monitor it looks absolutely gorgeous, my RTX3080 can max all the settings. As soon as I turn to VR however, it turns into a blurry, stuttery mess. Running an I9 10900k OC'd to 5.2ghz as well (stable, 24 hour burn tested!) so I doubt it's my CPU!

For this reason I still prefer using my Reverb G2 along with Open XR Developer Tools for WMR for MSFS 2020 only. I get pretty good results with that sim in the Reverb G2.

High clock speeds or not, no 14nm Intel chip compares to Alder Lake or Ryzen Zen 3. You would probably get ~25% better frame times with a newer cpu architecture with better IPC.

Interesting, has anyone had any experience with a CPU change from 14nm CPUs to Alder Lake?

What are the benefit and side effect of increasing Virtual Reality pre-rendered frame to 2?

 

Is it likely to introduce more ghosting when plane pass by with high deflection?

If you have frametimes increasing to near max of your given refresh rate at times then it helps smoothen such out - the so-called .1 and 1% lowest framerate. The side effect is that the more you increase this the more latency you introduce, it's not huge amounts of latency but it's there and you have a reduced sense of presence in the game (for me the perceived effect is that the head motion isn't quite as snappy) - at 2 you most likely will not be able to detect it (in seated sims; it can be quite apparent in twitchy quick action games) if you are playing on a headset that maintains 90Hz or higher. And no, it will not introduce any ghosting.

Thank you very much about your explanation!

 

I am struggling to find the fine-tuned settings that would reducing ghosting.

 

I have switch off retroprojection smoothing, but still see 2 planes instead of one, in high deflection combat situation.

With the G2 I have seen this situation in the past when my tracking was not working properly, for example in rolling scissors the opponent plane would appear as if ghosted as I moved my head to keep it in view while there was no drop in framerate. Things I have found that affected the inside-out head tracking so far are: LEDs on a USB hub that was infront of me, LEDs on the joystick (luckily could turn them off via the config sofware) and dirty camera lenses - also, most amusingly, a cat jumping on the desk and staring at that thing on my face at close proximity.

[Youtch]

Thanks.

 

I will need to look if the leds on my joystick and joystick hub and mouse somehow interfere.

 

I haven t noticed anything wrong with responsiveness in tracking though, but maybe the problem is indeed more visible when my head is moving.

[Youtch]

I hid all the leds and it did not make any difference, I make the test of making a quick roll not moving my head, and everything became blurry and planes ghosted.

 

I am running an average of 60 fps, could it be because my number of fps is not good enough to respond to quick movement?

 

Or I miss any other parameter that could induce/reduce plane ghosting?

 

I am generally quite happy with visuals and number of fps seems stable, but when doing scisor/high yo yo/high deflection attack, enemy planes go from neat to blurry to appearing double.

 

Thank you very much again in advance,

y.

 

Edited: to correct typo.

6 fps sounds very low, do you mean 60fps or do you mean 6ms frametime with 90 fps?

 

If the former then you are using 60Hz mode and indeed it will induce ghosting. IMO if you cannot use 90Hz mode then your only alternative is with reprojection enabled so at least it's a smoothed out 45fps with the panel working at its optimal refresh rate. Ofcourse you might encounter some reprojection artifacts but it won't be as bad as the constant ghosting.

[Youtch]

It is a typo. It was 60 indeed.

 

I will try the optimization you recommend.

 

Either lowering graphic setting to be closer to 90, maybe coming back to fsr mod.

 

Or trying to set reprojection with 45fps.
