They are essentially the same thing. FFR reduces resolution near the edges and VRSS increases resolution near the center. They both use Variable rate shading if you have an nvidia GPU.
But, super-resolution is very computationally heavy. If you have the hardware (e.g. 5090 GPU), you might use...
I posted an update about Fixed Favorted Rendering and upscaling in SteamVR. Please check the updates section of this guide.
In short: use 'openvr_foveated' instead of my plugin
cocogoat updated Yet another VR performance plugin with a new update entry:
SteamVR Users, use this plugin instead.
Read the rest of this update entry...
My updated plugin here will cause controllers to disappear in SteamVR.
If you are SteamVR users, please use this one from fholger instead:
https://github.com/fholger/openvr_foveated
replace the openvr_api.dll under ".\VaM_Data\Plugins" with the new one and edit openvr_mod.cfg for your setup...
I think if you want to abandon valve index and get a quest just to use this plugin, it's not worth it.... You should probably get a better GPU with that money.
If a lot of people found the plugin to be useful, I can also try adapting it to SteamVR. But I am currently not sure how...
It is actually a tool that you can adjust for you setup. You can reduce the center radius more if you want more performance, but you will have smaller part of image to look sharp.
You can also use upscale methods CAS, FSR, NIS but that also reduces graphics quality.
0. Tested on Meta Quest link and Virtual Desktop streaming. Does not work for SteamVR!
1. Where is the GitHub link?
Support me at: https://github.com/biorabbit/VRPerfKit_RSF
Building the project requires some knowledge with Visual Studio 2022 and git.
2. How does it work?
It currently performs...
Interesting. Another post suggested that you launch Vam through VD without SteamVR (my setup). Maybe you can refer to that.

I did not test this plugin on steamVR, There can be some compativility issues.
I am currently using quest 3 with RTX 4080 GPU + i7-14700k CPU. I am using Godlike streaming quality with VD and targeting 72 fps.
I am mostly playing VaM Produce 69 https://hub.virtamate.com/threads/vam-produce-69-ii-user-manual.70280/
My in game settings are:
render resolution: 1.0
MSAA: 2x...
It is currently doing fixed favorted rendering, reducing the render resolution near the edges. I heard that for some systems like pimax, this is already implemented. But for my setup (Quest with VD streaming) I have to make a custom plugin.
You can also use AMD FSR or CAS (upscaling) in this...
This is an updated version of VRPerfKit_RSF, modified to be compatible with VAM. It will increase performance by about 10 fps depending on the settings.
I do not have a SSL certificate, so it will be reported as a malware. Use it at your descretion or build it yourself from my Github repo...
