    More importantly Mario's patch has just landed in 4.9 to allow for tear free prime offloading between Intel and AMDGPU drivers

      Ok, answer if you know, what kernel version & nvidia driver version combo will allow optimus tear free rendering? Or is it not done yet?

        Holy moly. 4.9 release can't come fast enough.

        Could you point me to the commit/merge/whatever that indicates that the patch has landed? I don't really know where to look

          It's here: https://git.kernel.org/cgit/linux/ke...eba7da65a446a7 it's also being added to 4.4 & 4.8 but it's not landed yet, plus I'm not sure how useful that'll be as I think i915 fencing only landed in 4.9 - but it's useful for radeon / amdgpu systems

          There's also a patch on the mesa mailing list so radv works with PRIME it just keeps getting better and better
