Thanks for letting me know.
Since it was mentioned that the studio releases multiple games with the same exe name, are any of them 64-bit as well, do they use D3D11, and if so, have they been updated? If that's not the case it might be a good idea to keep it around for now.
Turns out their other game is named yo_cm_client.exe, not cm_client.exe as I mistakenly remembered.
It is 64-bit and ldd.exe shows it is linked to d3d11.dll, but I don't have it installed on a linux machine to test it.
They patched the game today to fix the 64-bit issue described in https://github.com/doitsujin/dxvk/issues/591 for which dxvk added the workaround in commit https://github.com/doitsujin/dxvk/commit/73cbf5b3524ffbba63c950608619a35ef872d8ad. This commit can now be reverted.
