New Performance Toolkit to VR

Teussi · Feb 6, 2022

Guys, found this new version of Fholger perfkit at iracing forums, tried it with iracing and it worked like a charm really! I'm now talking it with:

Fixed foveated rendering on and previous nis/amdfidelity off.

Tried it with assetto corsa, can manage to get the nis/amdfidelity to work, but cannot get the Fixed foveated rendering to work only.
Guys, really this is something good for vr, example in iracing i got -30% gpu usage and didn't really notice anything downgrading in image quality.

Here is the link:

there is also threads on reddits, check them out also.

Feel free to talk!

Answering to myself (and others)
Got answer from CSP discord: "FFR does not work with AC as it uses a forward renderer"
So no help with this amazing feature in assetto. Gotta try upscaling again if i can handle the aliasing

This fork made for DCS works perfectly in AC.

You kno whow to install for openvr and AMS2? I tried it like in this video but my zip file contains hundreds of files instead of 2?

NIS and FSR work. Thanks for that. But I can't get the FFR to work in AC. Is there another tip here?

You can find the two files here: https://github.com/cedriclmenard/vrperfkit/releases/tag/v0.2.2-dcs-ffr Unlike in the video, these must be read in the "...assetto corsa" folder. See the "Read Me.txt"

Stumbled a few times over this last weeks, so does it work with AC? Do we get more performance?
I hope someone shares more of their experience...

Little bit late from the party, but confirm this really works with assetto corsa! Dropped GPU frametime 2ms!!

The version here https://github.com/fholger/vrperfkit/releases (0.3 as of writing) works great in AC for me. I notice no image degredation on my Index and my GPU frametime drops by a couple of ms. I don't use the upscaling, just the foveated rendering. Press ALT+F1 to toggle it on and off in game. Thing is magic.

why use this instead of Openxr toolkit?

Can't you use both?

If you cannot see a degradation in image quality when using AMD fidelity, you should go to an eye doctor. I have never tried foveated rendering though. How many extra fps do you obtain?

Depends how large a radius you use. Something like 1.5 - 2.5ms frametime is saved using default settings on my machine. When you consider the entire frame is 9-10ms during the heaviest parts of a race thats very significant. Lets me pump up the settings. Can easily run 200% SS in SteamVR and hold 90FPS in all but the heaviest of car/tracks combos with nice shader and CSP settings.

There is one thing I have since noticed in my peripheral vision that is an image degredation though. I hadn't noticed before because I didn't have them enabled at that time but if you use godrays, there are certain angles that the sun shafts can look very blocky towards the edges of the screen. A very clearly delineated circle where the full res inner part meets the half res area. Turning them off as a workaround for now but will play with quality settings later to see if I can get it to be imperceptable.

Thinking of the wrong game. Ignore me..

It's not just godrays that I noticed. I just started using OpenXR and I've been VR only since like 2017 so all of this is new to me.

The people in the stands and some builds are not shown on the very outer ring which threw me off at first. I have to play with the settings I guess and see what I can change.

I tend not to use the outer ring at all, and have that at max radius so it has no effect. Could be that the OpenXR implementation is a bit different to the one I'm using though.

I'm also on a Valve Index so the peripheral stuff is less 'in your face' than on a G2 for example.

Sorry I was thinking of the wrong game. AC works pretty well with OpenXR for me at least. My comment was for AMS2 and in the wrong forum. So please ignore me

If have CM, Isn’t better to use this piece of Fholgers software https://github.com/fholger/openvr_foveated
As the rest of FHolgers performance tools are already available in CM and to avoid conflicts.

Upscaling techniques (render at lower resolution and upscale to target resolution)

AMD FidelityFX Super Resolution

NVIDIA Image Scaling

AMD Contrast Adaptive Sharpening

just a question?

edit: were to put the FHolger file into, is it Assetto corsa/System/X64 folder????
