Have a nice break, and please do HiZ if it is your domain. Thanks.
That would be great! For those who don't know what HiZ stands for, it means Hierarchical Z-Buffer. There is some code to support this feature, but it's stuck since August as you can see here and according to freedesktop's bug report it doesn't work.
The patches are easy to apply, and they work so well that I can use them with Star Trek Online running under wine with an evergreen card. It improves performance a great deal and actually reduces stalling significantly (one of the previous issues I was having is that it was "choppy", but not with 2d tiling).
Great work, Jerome! Truly one of the better things to hit r600g in a LONG time.
