Hi,

I have a Radeon 7970HD and I use the Gallium Nine state tracker to play a
specific game (EVE-Online). I did notice that the performance take a big dip
when used with the kernel 4.7-next and -rc1. I did know about a regretion
affecting some opengl game, that might and might not be related.

Using the kernel 4.7, I lose about 1/3 to 2/3 of the fps depending of the
situation.
