Note: As mentioned in my previously submitted issue, this problem is not related to DXVK itself, but there is still an obligation to inform. I have also posted the same issue on NVIDIA's official driver thread. This issue here is for NVIDIA official personnel to track.

The 580.88 driver fixed the 32-bit DXVK game crash issue, but consequently 64-bit DXVK started having problems.
This has been tested and confirmed in multiple games. (Source SDK Base 2013 MP, Team Fortress 2, Insurgency.)

Note 2: Not sure about the principle, but some games won't crash if launched through SpecialK.

The following are the DXVK logs and crash logs exported by SpecialK respectively.
gmod_d3d9.log(VK_ERROR_DEVICE_LOST)
crash.log(Points to nvoglv64.dll)
