I’ve been using a 4070ti for a few weeks now, combined with a 5800x3d and 64gb ram and a quest 3.
I wanted a 4090 but it would have cost me an extra £1000 and I couldn’t justify it.
Overall I’m pretty happy with it, I’m getting a smooth 36fps using mxaa x2, and everything looks pin sharp.
I use debug tool to set fov at 0.8 and open Xr toolkit with turbo mode on.
On occasion it will hit the the vram limit but if I turn textures down to medium it’s fine.
I’m sure a 4090 would kick its ass but for what I spent I couldn’t really be happier.
