Unity VR build issue

Hey, I'm currently streaming a Unity PC VR game on the Oculus Quest 2 using a Link cable. I've incorporated an interior space model into the game, but I'm encountering an issue. When I set the render scale to 2 and enable 2x antialiasing in single pass mode, I experience significant lag. However, when I reduce the render scale to 1.8 and keep the antialiasing at 2x, I begin to notice distortion/melting effect—this wavy effect when I move within the space, which is a bit annoying.

I could really use some assistance with this issue, especially considering that I'm using the single-pass rendering mode. Any advice or suggestions would be greatly appreciated!
