--- Comment #7 from Richard Yao richard@ryao.dev --- Also, after the initial start of GeForce Now, it will restart with a black screen due to some deficiency in D3D11 support. Installing DXVK will resolve that.
If the connection issue is fixed, there is at least one more issue that needs to be resolved, which is to get AV1/HEVC decoding support working, as it is very unhappy without it:

That can be seen in `~/.wine/drive_c/users/${USER}/AppData/Local/NVIDIA Corporation/GeForceNOW/geronimo.log`. There is much more, but I am limiting it to that to avoid spamming the bug.
