One might argue that you can run PhysX calculations just fine on the CPU, and
the GPU accelerated PhysX (cuda) is not required, yet afaik a lot of games will
check for nvapi/nvcuda to enable this. If nvapi/nvcuda is not present, the game
option is not possible to enable. (Aswell as the PhysX software itself ofc).

Some games like Witcher 3 uses CPU for PhysX calculation without (afaik) the
option to enable this on the GPU.

Other than games i am not currently aware of any useful apps you cannot get to
run on Linux directly using libcuda.
