TM significant quality drop when switching to VR

Hey i experienced a significant quality drop when switich to VR Mode in Twinmotion

before entering VR Mode the picture looks like this with all its lumen beauty etc:

i dont know what happens everything is set to ULTRA and DX 12 no dynamic quality etc.

The Headset is a and connected with a cable to my PC :

Meta Quest 3

Ryzen 5950x
128 GB RAM
RTX 3060 12 GB.

Do i need a 5090 for that? I mean its pretty laggy for such a rudimentary geometry / task

thanks in advance!

A significant quality drop in Twinmotion when switching to VR is common, even on high-end hardware, due to VR’s higher rendering demands per eye, Lumen lighting limitations, and software optimization issues. To improve performance, lower graphics settings, adjust VR-specific options like supersampling, and ensure GPU drivers are updated. Upgrading to a more powerful GPU can also help maintain visual fidelity in VR.
