I sure hope 8.1 has both these included -- I wonder if 50% up is a reasonable expectation?
(based on the '20-30%' for 2d tiling, and a wag of similar improvements from HiZ)
Anyhow, is there a git branch somewhere with patches applied?

Save, in EVE-Online after +- 20 minutes...
The GPU started to chain soft-lock until I magic-key reboot with the yesterday kernel.

So far, so pretty good... working well with Linux Mint's cinnamon fork of gnome-shell, and I had a stable experience running Star Trek Online with wine 1.4.0-rc2. Well, for about half an hour, and then I got GPU soft lockups and had to kill X, but amazingly didn't have to reboot.
Seems like maybe an instruction got emitted that didn't bounce off the CS checker and caused the GPU to lock up, but the driver was able to reset it:

Just the other day I was wondering why the Z reject speed on my r700 sucked. Looking forward to this being in master.

Even HiZ for R300g isn't still enabled by default (and it will probably never be).

How is the current state?
Do we have any benchmarks?
