Catalyst 5.7 Drivers: Memory Limited Performance Improvements

X800 XT 256
Another glaring issue that we ran into with the new drivers was what appeared to be a small performance hit with some of the higher memory cards. On the X800 XT, FarCry's framerates for all resolutions without AA enabled actually went down with the 5.7 drivers, although only very slightly. As you can see, there is at most about a 2 fps decrease here, not enough to cause a problem with game play, but it's still a loss. This is most likely due to unnecessary swapping. With these higher memory cards, ATI's HyperMemory is actually causing the slight loss in fps because of the extra computation time needed to swap out data from memory. There aren't really any losses with the other games on this card, and even in FarCry, the lower framerates with catalyst 5.7 without AA are still very playable. The only significant decrease in framerate because of this bug here is with FarCry at 1920x1200 with AA enabled. The framerate drops from 25.6 fps with 5.6 to 22.2 fps on the 5.7 drivers; about a 15% decrease in performance. This would definitely cause a noticeable difference in game play, but the initial 25.6 fps would have made most people change their settings anyway.

Where can I download the 5.6?I have a new ATI X800np w/ 256MB and I downloaded and installed this last Tuesday. I notice a small drop in 3DMarks2001 but just shrugged it off as the result of solar flares or whatever. It would be nice if ATI warehoused their older drivers and made them available.

Did you look even look?At Ati site

They are all there since Catalyst 2.1 or even older.

Try http://downloads.guru3d.com/download.php?id=18">Guru3D - you can get practically every past driver version for ATI and NVIDIA cards there.JustAnAverageGuy - Saturday, August 13, 2005 - link
I'm still running the 4.6 drivers because 4.7 makes the textures in Battlefield 2 go crazy with my 9800 Pro.Gamingphreek - Saturday, August 13, 2005 - link
Where in the world are they pulling these framerate increases from??They have had 3 years to perfect these drivers, why all of a sudden are we seeing 0-10fps increases. Is ATI using shader replacement on more games? Did IQ suffer at all.
It just seems hard to believe that these drivers based on the exact same architecture since the 9700 still have gains of 10fps left in them.

Did you even READ the article? ATI implements HyperMemory on ALL cards with 128MB and less of memory.ecvs85 - Saturday, August 13, 2005 - link
I have a question, since this hypermemory is a software based memory management software that makes use of the system ram, what about the AGP aperture settings in the bios? (well for agp boards)I got 1GB of ram and when I set the AGP aperture to 256MB I don't have much issue running games that need more that 128MB of video ram (which I have 9800pro). So is the hypermemory smooths things out, having less stuttering and results in higher overall framerates? If that is the case then I don't need to upgrade to this driver :P

ATI's drivers have been going downhill lately. I don't care about gaining a few fps especially when they cause more bugs than they fix.I still use the 4.12's.

dang yo'z.i never had an issue this past year with ati's drivers.
besides my all in wonder not playing DVD correctly. no freakin idea why or how. reloaded all of it 2x and it stil doesnt work right. Cyberlink PowerDVD is what i use now, a shame though as ati's was very nice and integrated. I have a 9800 PRO AIW.
I dont knock ati, i mean, that whole intelligent CLI thing i have running actually works really well for games, i think everyone forgot about that. Works for new and old, i see lag on startup from it as it "thinks" for an older game, runs great though.
I still want to go nvidia myself for new system if I cant manage to run ATI allinwonder x800 XT on a linux system.
What's up with ati not putting out faster/better gaming Linux based drivers like nvidia does? that's a tad self defeating for such a giant in the industry.
I mean nvidia doesnt even make graphics cards! its not the big of a company! (only chips and chipsets and designs)
