# When I play the game through proton, I found that in the case of Dual-Direct GFX
# enabled (dGPU disabled), proton will crash directly. But in the case of hybrid,
# the game runs fine with or without nvidia-offload After investigation, this is
# because when writing the specialization of Dual-Direct GFX, I did not completely
# remove all packages for amd igpu. I only removed amdgpu from
# services.xserver.videoDrivers by overriding. This is because the specialization
# of nix cannot implement such an operation as canceling an import. In the end, if
# it is enabled in Dual-Direct GFX In the absence of amd igpu, the amdvlk package
# caused the proton to crash. In order to solve this problem, I add the option of
# whether to enable amdvlk to the configuration file of amd gpu, and open it by
# default, and turn it off in specialization, so as to delete amdvlk package and
# other packages for amd igpu in specialization. At the same time, I also added an
# option to amdgpu's opencl runtime.
