That is compatible with what the comment you are replying: you don't need much to beat nVidia open drivers for linux. Intel linux drivers might be behind their Windows drivers, still ahead of nVidia's.

nVidia has zero incentives to play open for linux, they release the binary blobs, next to zero docs and support, and you deal with it. The last nVidia card I bought was 20 years ago, and it was so bad for linux (low perf and freezes for the open drivers, manual re-install hell and pray on each kernel update for the binaries) that I switched to ATI. Since then, ATI or Intel always were decent with zero headaches.
