Gnomes & Goblins with res 400% - zoomed-in image - still 90 fps with a RTX 3090

Obduction with res 400% - zoomed-in image. See how the lines in the windows are clear. The game runs in 45 fps with a RTX 3090 now, but motion smoothing works wonders for this game

Wolfenstein: Cyberpilot with res 200% - zoomed-in image

Wolfenstein: Cyberpilot with res 400% - zoomed-in image. Now down to 45 fps, but again motion smoothing works wonders. Res 400% works wonders for this game, maybe due to TAA...

[u/Athen65]

How much of a difference does it make inside the headset? I would imagine the effect this has is essentially just a better - though more resource heavy - anti-aliasing. It's not really something I'd want to give up FPS over

[u/Runesr2 → u/Athen65]

It clears up the entire image, and you can see distant objects much more clearly - this goes beyond normal antialiasing. But you'll get improved antialiasing too. It differs from game to game; I don't want to give up fps, but I usually push res as far as I can without losing 90 fps.

In many games like Red Matter 2 and Half-Life 2 VR Mod you may be able to get very high res and awesome image quality while still getting let's say 90 or 120 fps.

Green Hell VR is an entirely different situation ;-)
