@dibelabbes it was just crashing with 100% scaling … that was the reason, not the power of the graphic card. Maybe they already fixed this issue

Big tip: The ingame VR settings regarding table positon only work in seated mode. There is a popup when you start the game that allows you to switch between seated VR, standing VR and none VR. For whatever reason though that is missing when launching from Steam VR or Virtual Desktop instead of the Steam desktop app, in which case it defaults to standing VR.

You can force it to always launch in seated VR by adding this to the command args:

-vr seat

Just for people reading this now (arguably this is 3 years old), this part isn't at all that universally good advice: "set scaling in for the game Steam VR to 80%"

In truth, it depends on the speed of your GPU and your headset, because 100% render resolution in Steam VR is in relation to the resolution of your headset, i.e. its a whole different amount between a Quest 3 for example and a Beyond.

I personally would advice setting MSAA to 4x (or higher) if you can reach 100% with your desired frame rate and the other ingame settings (like reflection quality) you care about. Afterwards, raise the render resolution up further.

With a Quest 3 on a RTX 3080 for example I play at 4x MSAA, IIRC 135% render resolution at 90 fps. If you have a newer GPU, you can push even more.
