Symptoms

This is on a Manjaro (Optimus) laptop (MSI Cyborg 15 A12VF) with an NVIDIA RTX 4060 Mobile.

The game is launched with prime-run %command% and runs perfectly (120-140 FPS), confirming the NVIDIA dGPU is in use.

However, the game hard-freezes (process hangs) 100% of the time when joining an online multiplayer match. The rest of the OS remains responsive.

This appears to be a specific conflict between EasyAntiCheat (EAC), the NVIDIA driver on an Optimus setup, and Proton, as the freeze only triggers when EAC activates for multiplayer.

(Note: The attached Steam System Info Gist incorrectly shows the Intel iGPU as the primary driver, as is common for hybrid graphics laptops, but the game is definitely running on the NVIDIA dGPU, confirmed by the high FPS).

Reproduction

1. Launch REMATCH (AppID 2138720) on a Manjaro/NVIDIA Optimus laptop using prime-run %command%.
2. Get high FPS in the menus (120+), confirming the dGPU is active.
3. Join any online multiplayer match.
4. The game will freeze during the loading screen.
