Sure I’m missing certain aspects to this as I’m not extremely tech savvy, and need clear direction when I try to make changes. My reason for posting to this topic is to simply let the average user know that these adjustments are probably for advanced users only. File paths and locations are different for all of us based on how things are downloaded within the OS. That being said I tried this and it seemed like it was working, however I must have made changes to the wrong file as after restarting steam a couple times all hell broke lose and my frame rate and performance went by the wayside. I’ve since changed everything back. Perhaps there is a final way to write this topic in dummy terms for the less fortunate (like myself) that don’t fully understand these changes.
I might do this for the IL-2 community end of January. Heavily loaded with work right now. I’ll link to it then here, if none else has done it yet
Hope this helps, I wrote a 5k+ steplist earlier: https://community.openmr.ai/t/best-quality-settings-for-steamvr-ive-found/22614/48
The only difference since then is that I now run 8532 on Normal FOV instead of 4266 and that still keeps my baseline 45FPS in stations on my system with Motion Smoothing and FFR Conservative on, and finally HMD 1.25 in-game via EDProfiler.
I made a post trying Large FOV on 17064. Text clarity amazing but I only get 30FPS in stations on a 2080 Ti https://community.openmr.ai/t/after-mrtv-ces-8kx-large-assetto-corsa-maxed-out-5k-large-elite/24979/1
@Octofox Octofox, please be aware that there is a mistake in that algorithm that you may want to fix.
You’ve set 4266 as horizontal number. These numbers vary between the 3 different versions of 5K+ though (SN 202, 203 and 204), and also in regards to the 8K.
If people should find the correct number for them, they must
close SteamVR
Pull PiTool RQ to 2.0
open SteamVR, pull SS to 100%
read horizontal value, divide by 2, write down
turn off SteamVR, navigate to steamvr.settings
put result into maxRecommendedResolution
put supersampleScale to 0.25
This is interesting @Gared, and it make sense that at certain step upsampling/downsampling will produce better results, thanks for sharing this.
Curious if anyone tried comparing FPS at:
Pitool: 2.0/SVR: 0.25
Pitool: 1.0/SVR: 1.00
Pitool: 0.5/SVR: 4.00
(all seem to require same resolution from the game).
I did. There is considerably more pixel and horizontal line flicker on the “oldschool” settings. The one Gared posted is much softer.
I can say without tests that with pimax SS=2, FPS will be slightly less. Since with the same number of pixels on the side of the game, more work is done to HMD distortion. But you lose less information at the stage of distortion in this case. Which leads to an improvement in quality in the end.
wow, there’s something going on there indeed. I think I am getting slightly more clear image with 2.0/0.25 vs 0.5/400 (Gared’s suggestion looks better). There’s something objective as well: I get VRAM usage difference 8560 vs 8290 (reproducible), so it is not just about requested resolution, something else is happening.
Since we don’t get any answers from Pimax devs (which is fine), if someone is bored and has time/desire, maybe more can be figured out by debugging GitHub - JamesBear/directx11_hellovr: A helloworld OpenVR program written with DirectX11. using RenderDoc or something, but… I CBA 
just happy to slap better settings and call it a day. Thanks @Gared, once again. Cheers!
Hey JoCool, agreed everyone has to check their own values against Steam’s recommendation. My 5k+ value is different to Gared’s 8k, and I don’t know how the SN affects this for the various 5k+ models.
As mentioned on the steplist, I based my number based on what Industria posted and what I saw for myself at PiTool 2:

@Heliosurge I’d update that steplist post but I don’t seem to be able to edit it again. Is there a limit on post edits?
My steamvr.settings file keeps changeing to 0.3xxxxxx after playing a game, even though no values have been set in pitool for the game.
Any thoughts ? (yes I am making changes in the correct file) 
as I only have 1 config file
This is caused by having Advanced OpenVR Settings installed. It’s one of the reasons - there might be more. Also, check if you have forgotten to set the maxRecommendedResolution.
There is a limit on number of post edits.
I would use reply to your original Blockquote looks like a speech bubble.
Make changes. And remove quote
Alternatively can make that original post a wiki.
Just kindly link me to the post number. 
Sure thing thanks

It is Done. Once you folks have ironed things out to your satisfaction. We should repost your guide in an easy to find place.
Awesome work.
Thanks @Heliosurge will make a few tweaks when I can and let you know And of course big thanks to @Gared for bringing this to our attention in the first place
I compared those two and had no difference in fps and both looked the same in iRacing.
if you are still curious, check out VRAM usage difference (MSI Afterburner). I tried two extremes: 0.5/4.0 and 2.0/0.25 and saw clear memory usage difference in rF2 indicating that there might be something else going on other than resolution requested change. It is possible I made a mistake as well as process involves copying/renaming/editing files, so would be interesting if someone else confirms my findings. I’ll also check what actual res is requested from the game sometime in the future.
Well, Kevin said a long time ago that “oh, it does more” (than just change the supersampling)
It might have been in the first MRTV Kevin interview.
