+  # the game runs fine with or without nvidia-offload After investigation, this is

+  # services.xserver.videoDrivers by overriding. This is because the specialization

+  # 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.
