Sure, a few specialized applications can, but Rack can’t, at least not yet and I don’t see that coming anytime soon.
Well, Rack needs a certain minimum amount of “GPU power” for its graphics rendering and builtin graphics are notoriously weak (except Apple M1 machines). Whether the old GTX 760 2GB card is better I couldn’t say.
If it works better for Rack it’ll work better for everything else, I can’t see why not.
