    Yep. I think the usual protocol is roughly :

    * can cause problems even when disabled : in a branch
    * code works OK when feature is disabled, works for "some people" but not "most people" when enabled : in master but disabled by default
    * works for most people : enabled by default

      My experience was the opposite, HiZ seems to work pretty well in most games, but there are a few notable exceptions, which I guess is the reason why it never has been enabled by default.

        Isn't the lack of optimisations in the shader compiler another big bottleneck?

          It's possible, but the three things I mentioned are major performance boosts which alone might get us from ~60% to pretty damn close to Catalyst.

            Call for testing for HyperZ on R600g: https://bugs.freedesktop.org/show_bug.cgi?id=36602

              Anyone can edit RadeonFeature, registering is open.

                Agreed, I get artifacts with HyperZ and WoW too.

                I need to disable HiZ to remove artifacts: RADEON_DEBUG=nohiz. This is with my M66GL (RV535?).
