The more I read the opinions and settings of various simmers the bigger this question gets.
The native resolution of the Reverb G3 is 2160 X 2160.
I read simmers using resolution and over-ride resolution well beyond the native resolution.
I understand the math in re-calculating for barrel distortion. I have my VR set at 3160 X 3124.
Is there any benefit in utilizing higher resolutions beyond the native. It also burdens the graphics card even more. I have a RTX3080ti currently.
Thanks in advance for your considerations,
Supersampling is used in VR for ages in all kinds of games. It just returns a sharper image. If you try it you will see the difference. Also, if using DLSS, supersampling can overcome the blurry glass cockpit text in native resolution. Everything just seems sharper even using DLSS Balanced + OXRTK supersampling at 4000x… pixels or up to 4200x… After that it seems to lose the advantage. I’m still experimenting on what is the best visuals to performance ratio.
Reverb G3? Never heard of it. If you are talking about G2, the higher rendering resolution also improves the sweet spot. I recently upgraded from 2080ti to 4090 and immediately moved render scale slider from 50% (2160 X 2160) to 100% (3164x3096) for all games. The image is a lot sharper but obviously it requires a lot of GPU power.
I don’t know why, and can’t tell you if the image is better, but with my Valve Index running a 13900k & 4090, render scale at 100% gives me terrible performance, and I have to move it UP to 130% to smooth things out.
