So, in multiplayer lobby game just use 3d on my cpu integrated graphics instead of graphics card. And run full load on cpu.
Im not hosting the lobby.
CPU Ryzen 5 3400ge, gpu P106-100 with 1060 driver's (trough m.2 to Oculink hub). Win 11 Pro.
In different games gpu works ok (like Fallout 4, Doom etc.)
