I don't know, but after reading Dave's post above I felt there might be a restriction. I don't have an X1xx to verify this, though.Jawed said:

Dunno - whatever it is that you use to set texture filtering quality to HQ.DegustatoR said:
The performance hit from HQ is bound to be less than the performance hit of turning AI off.
As far as I know I can't run CCC here on my Radeon 32MB SDR, so I dunno the exact procedure.

IIRC, the CP has sliders that go from 'Performance' to 'HQ' for both texture and MIP-map quality. ATT does, anyway. But does CatAI supercede other settings (namely, WRT trylinear, etc.)?
ANova, is Humus' Doom 3 fix only enabled with CatAI? Just thinking of one example of an app-specific performance boost. I would think ATI's recently-found D3 AA perf. fix would be independent of CatAI--that is, not user-selectable--b/c it's a perf. win that (ostensibly) doesn't affect IQ. I mean, if CatAI is just for IQ-independent features, as Rys first said, it would seem stupid not to have it on all the time, as making it user-selectable would be akin to offering a "Slower and Dumber?" checkbox (like trying to enable AA with Halo or PoP). IMO, it makes sense to make it user-selectable only if it affects IQ, which is what I understood it to do (with CatAI High being [more] aggressive in toeing the optimization/IQ compromise line). End-users don't need more choices to make regarding tech they probably (don't care to) understand, especially if the choice is a no-brainer.

Here is an article which shows the performance :

Amazing. Even though the real boosts are with 4xAA, it still looks lke ATi has finally gotten their OGL drivers up to parity.
This was a gem: "Unfortunately, ATI accidentally uploaded the wrong file to their support site initially. On Friday we contacted ATI and were able to determine that the file originally uploaded to the site, hotfix_xp-2k_dd_ccc_027483.exe, wasn’t the driver with the OpenGL performance enhancements."

Looking at Q4 and these performances I'm wondering if the game isn't quite Vertex limited.
Holy crap.
Ati>nvidia in quake 4.
Nice.
Thats good for the XT(which it' superior memory bandwidth it should be expected that it win), even better for the XL(which doesn't hold a theoetically advantage to the 7800gt.)
WIth fsaa, an XL is enough to match a gtx:smile:
Now we wait for nvidia's reaction.

Maybe because they tested noAA/8xAF instead of noAA/noAF as other sites usually do?
normally I hate it when sites test without AF since nobody will ever play a game that way, but this time it might be interesting to see where the performance gains come from.
On a side note, I wonder how many sites will not use the patch because they refuse to turn AI on?

I think Doom3 always runs with 8xAF if the high quality mode is selectedmjtdevries said:
