FS2020 VR + Pimax Discussion

Hi @camera,

Great advice!

Thank you so much for pointing me in the right direction! Starting SteamVR from within Pitool eliminated the artifacts on the side in MSFS.

What is the difference between 60 Hz and 75 hZ with 8k x

IF the game has a frame rate lower than 60 Hz ?

Happy to help, there a lot of negativity regarding Pimax and ms2020 here if i can help eliminate a tiny bit of it - all the better

Dont panik, the web is full of negative things about every HMD and MSFS :joy:

Difference is, 60Hz is a better match for anything desktop related, and requires less CPU/GPU to keep up with.

Anything above 30Hz is workable with Smart Smoothing.

At least we crossed the threshold that making such a simulator these days without VR support was commercially unthinkable. Though even MS should have easily been able to anticipate that, they did not, and obviously did not adequately invest in architecture planning.

Mine is totally buggered as well like this. I have a 5600X CPU and I’ve tried it with an RX 6800 GPU and an RTX 3090 but that made literally no difference. Something’s definitely not working right, it can’t just be performance with such a low Res.

I know. I’ve tried everything. I get major lag turning my head. @SweViver seems to have the magic touch! :wink:

It’s boggling how GPU usage is practically nil.

now this is a useful post. Bookmarked!

english by any chance?

Reminds me of the G2

with smoothing that 30 becomes 60. But its weird because I thought the game internally could turn 30 to 90? @mirage335 is that only OpenXR?

No. If any such mechanism existed, I would almost certainly have found it, and it is highly unlikely (essentially impossible) MSFS2020 or any other game can do this without FPSVR reporting ‘seeing’ a framerate above 30Hz.

No. None of the motion smoothing techniques currently available for any publicly known HMD or GPU have sufficient buffering to tolerate less than half framerate.

No. Even if you could triple framerates from 30Hz to 90Hz before sending to framebuffers, for VR, such a low framerate without motion smoothing would result in double imagery appearing.

No, no, no.

so i installed graphic driver v 452.06. in-game I have turned off many thing or set them to low / medium. Global rendering set to 60/70 (didnt really make a difference tbh) and no matter what, couldn’t get over 20 fps. getting 25 fps would be like getting an orgasm…

btw something is not right with steam vr. when i start it FROM PITOOL, The performance of my computer goes down, and i get an error message that steam vr needs to restart. Mouse cursor starts to jitter, web browser is laggy as hell and it takes ages to start any game. once i turn steam vr off, everything gets back to normal.

when i start it normally in steam app, all is ok.

Steam VR 1.15.16
no OpenXR

pitool v 1.0.1.266
headset firmware 2.1.255.294
native resolution
steam vr set to 30% (around 3800 horizontally)
1.5 pitool render quality
PP ON
Smart Smoothing ON

nvidia 2080
driver 452.06 (optimized for MSFS 2020) - I had the newest nvidia driver installed too, but it made no difference.
32gb ram,
4ghz i7 8700 intel

No idea what is causing all the issues or what settings should i use to get at least 30fps and decent resolution.

hmm in fpsVR I am getting 99-100% gpu usage and the graph is completely red. And 16% cpu usage. No idea if the reading is correct.

FYI openxr does exactly from 30 to 90 and it works as any other “smoothing techniques”…

Interesting. I guess OpenXR is at a layer that makes that possible, doing its own motion smoothing…

I would not have expected that to have been implemented at this point in time. Maybe all the more reason we can drop SteamVR.

Since Pimax is 3rd party, maybe they should adopt OpenXR as an option.

That may not help Linux support, and we need direct access to frame buffers for a lot of things. OpenHMD supports OpenXR, and that is the way to go.

Pretty sure you’re wrong on this one.
