No. Its been said a number of times, here and elsewhere, to expect features from the 3.8's, not necessarily performance increases.

It is that not necessarily that gives them waggle room for this.
Especially given that what sireric has been saying about it not impacting the shorter shaders which are in common use now. Which means you wouldn't see a lot of a performance delta with existing titles, just ones coming.Anyhoo you are most likely right. I am curious to see exactly what features are in these drivers because they have been very excited about them.

The FireGL driver updates are somewhat less frequent than Catalyst updates, but I believe some improvements are being made in that area.

Hope that answers all the Catalyst 3.8 driver questions
Thus all the talk about this Catalyst release being much more of a feature release than a performance release, that makes a lot of sense.sireric said:
Thanks SirEric.

And Catalyst Maker commented on this over at R3D I believe. Methinks Digitalwanderer hasn't visited enough forums yet.
lol. I think digs family would get far more attention from him if they had their own family forum.

It'd be a lot funnier to me if I didn't have to cook three different bloody meals every night for each member of the family.Kalbaz said:
(Unfortunately I'm being dead serious. )Thanks for reminding me it's garbage night, though they've been coming later lately so I don't usually put it out 'til the morning after I drop the kids off at school.
digitalwanderer, thats no big deal... I usually have cooked at least three meals a night just for me oh and a few fast food runs during the day too... well sometimes noone cooks for me and i end up having to do it myself and do stuff like have to open a can of cranberry sauce with a butter knife (like last night...)

Nvidia has dramatically improved the performance of shaders with their unified compiler. From terrible to almost reasonable. Would you see such a gain reordering instructions on ATI's architecture? I thought the half life guys were saying that code ran close to optimal without a great deal of optimization.
rwolf - ATI have had a rudimentry optimiser since Cat 3.6. Probably if you think about the difference in the hand optimised shaders in 3DMArk03 to the default ones, thats probably the optimal that the shader compiler has to reach.
Oh yes, much more advance stuff coming up. Not sure on the exact performance improvements. Certainly "small" shaders will not get much improvements, but more complex ones will benefit. DX9 assembly already maps very well to R3x0 (it's a natural), so there's no mysterious 60% improvements coming up, but some good stuff is there...
