%description
Internally uses bbswitch kernel module to switch video adapter power state.

Useful for pre-Turing GPU generations without dynamic power management features,
allows to fully benefit from NVIDIA PRIME Render Offload technology
without need to keep graphics adapter turned on all the time.
