The drawback of having a relatively recent, fast laptop: FOSS support is very limited.
#OpenBSD has no support for Skylake IGPs (e.g. HD 530) or NVidia GM107 (Quadro M1000M) yet.
#Nouveau's support for it is very basic, so a GPU that's massively faster than the IGP still stutters during basic tasks like video playback.
And I can't use the binary NVidia drivers because grsecurity says no.
I have no idea about writing GPU drivers, but if I can help anyone with accelerating this, please do tell.
