Kinda mostly not a thing anymore. DX12 / Vulkan closed up the last remaining notable gap here. Particularly as consoles became more PC-like in OS-level restrictions to combat piracy, and PCs added more low-level interfaces to improve performance. Console optimizations these days is mostly just dialing in the settings & using liberal amounts of up-scaling (which the PC versions also often support, but is disabled by default)
