I just tried it and let vorpx change the game settings – it set it to 1708×1280 fullscreen.
Bumped clarity up to full, was getting full 90 frames in Gonarch’s lair map. (3080ti samsung odyssey)
Alt enter sometimes restores a games focus if that was somehow affecting you. Only change I had made in the nvidia control panel (besides adding the vorpx custom resolutions) was to perform scaling on GPU (override check / set to aspect)
Do you need virtual desktop while running vorpx with the Quest 2?
