Freeze in VR with SteamVR

I have a problem with my VR game that I can’t solve.
The game freezes when I launch it in VR (see attached photo).
In desktop it’s perfect, there’s no freeze.
I’ve tested it on several configurations and I have this problem on small CPUs. Do you have a solution for optimizing the game on the CPU side ?

CPU : i7 7600k
GPU: RTX 3090
Ram: DDR4 16GB
HMD: HTC Vive Pro 2

On your keyboard ^^
