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:

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?
