Oh hey, that's great... am I the only one who got bored of Doom III over a
year ago?

Whether or not you like Doom III has nothing to do with the implications of
this achievement. ATI *may* shed the stigma of bad opengl performance and
apply this same tech to other opengl games.

A little late for Doom3, but still welcome since the fix works for other
OpenGL games. Since it only changes the way the pixel ROPs are accessed
during Z-compare, it's not going to impact image quality.

Except you can turn image quality up without as much
reduction in performance

This is great! Guess I'll have to wait for the 5.11 release to take
advantage of this. I always ran no AA in Doom3 due to the major performance
hit it took. Plus, Doom3 always looked clean to me without AA @ 1024*768.
Do you think this will increase performance without AA enabled? I've already
beat Doom3 two times so I might just apply this and finish ROE a 2nd time to
check the performance gains.

- You need an X1800 series (R520) video card to realize these performance
enhancements. X800 and below = no go.
- Assuming you have the above, you most probably would not see any speed
improvement when AA is not enabled.

Now that Beyond3D has done some digging:

The patch is not an enhancement, just a stupid bugfix. Before the patch, 4x
FSAA performance in Doom3 was actually slower than 6x FSAA. The patch brings
4x FSAA performance to where we expect it to be.

Of course, nobody tested the X1800XT at 6x when it paper-launched because
the 7800GTX doesn't have this mode...
