A major breakthrough for ATI Cat 5.11: Doom3's performances increase 35%

THIS JUST IN on HEXUS site:

"HEXUS.beans :: ATI produce tool to increase Doom3 scores 'up to 35%' with AA enabled
Posted on Thursday, 13 October, 2005 by Ryszard
ATI Technologies have this morning made a tool available to HEXUS which supposedly improves scores in Doom3 when antialiasing is enabled. Improvements 'of up to 35%' are explicitly mentioned by sources within ATI. The tool seemingly changes the way the graphics card maps its own memory to better deal with handling AA sample data in Doom3's case.

The fix will shortly be rolled into CATALYST 5.11 according to ATI sources and a beta drop of that driver will be made available for testing in due course, before the final WHQL driver from Terry Makedon's CATALYST team is made available for public download in November.

HEXUS are in the process of testing the fix and we'll bring you some scores using the executable tool very shortly. It's unclear if the fix affects other games or whether it solely affects Doom3 via ATI's application detection scheme and their ability to reprogram the GPU's memory controller per application using CATALYST A.I.

More on the tool and the fix as we get it. "

If this is true it'd be a major breakthrough for ATI and I hope it improves some other sim games I'm playing like PF-IL2 or FS2004.
 
That's cool, it's been wanted for some time 😉

Hopefully this will make ATI just as good, if not more so, for prey/Q4 etc games based on the d3 engine...

EDIT: note 'up to' 35% 😉
 
This looks a lot more like a bandaid on Doom3 than a fix for their truly sad OpenGL performance. If your summation is correct, it really only effects AA performance, which doesn't change the fact that even base performance (no AA/AF) in OpenGL is pretty much crap on ATi cards. Whatever happened to the full OGL rewrite?

edit like dug: Up to 35% typically means they tried it at the most inanely high setting and went from 15 to 20 fps. Grain of salt.

It is quite possible that if ATI rewrites and increases their OpenGL performance considerably, they may well be sacrificing their Direct3d performance. Maybe this is the reason they are just refusing to do it.

couldnt agree more....to me it looks like ATI's OpenGL performance deficit actually got bigger with their new cards.

35% isnt really useful ass you have said. 10fps to 13.5fps is a 35% increase.....but its still no good. we need proper numbers.

How so? The OGL and D3D teams are completely seperate.

It shouldn't, the drivers themselves are seperate driver components.
 
Yep, OpenGL & D3D are mutually exclusive. Probably the lazy ass team at ATI (in-charge for rewriting OpenGL drivers) may be reaching their life-long goal. 😀

They better do something for their Linux drivers too. :|

the links posted by haelduksf made a significant difference for me with a 9800 pro certainly...

I'm in agreement with the others here keys...I don't think the two are linked so I doubt it's the reason. I'm thinking it's more along the lines as to why their Linux support sucks...they just haven't figured out how to do it right, or simply don't care.

I don't see anyone installing separate OGL and D3D drivers. The "teams" you mentioned may be separate, but not completely. The end result is, you only install one driver that fits all. I don't disagree with you. Just have another perspective.

 
Did some reading, its not an Doom3 specific rewrite. Apparently the boost only works on X1K series of cards as the improvement is in relation to the new memory bus. :Q
 
keysplayr2003: Yes but the OpenGL and DirectX use different files which means that they are separate. The one driver includes the files needed for OpenGL and DirectX

So does this mean that ATI's OGL team is just composed of poor programmers? Or is the hardware not capable of good OGL performance.

i think it's more the former...their OGL drivers simply need a full rewrite...as i understand it...

Stick it in your pipe and eat it gorrilla man. quit living in the stone age.

if you played doom 3 on a GTX you would most certailny be playing with AA on.

ATI has beaten Nvidia in DOOM 3................at 1600x1200
Let it be known that the you cant even brag about doom 3 performance anymore. that game sucked but its followers will likley not.

I can not belive this thread is not getting more attention.
This is major news for ATI beating nvidia in their unbeatable doom 3 fortress.
This i belive was the benchmark to see if ati could come up with a monster card,,,,,doom 3 performance compared to nvidia.

Damn, I never thought this would happen. :shocked:

The programmable memory controller sounds awesome, it looks like such significant boosts are possible even in D3D.

Every time I make my mind up for that ever eluding 7800GT, one thing or another always crops up. 😕

Or does it mean Nvidia can't write a DirectX driver to save there ass? Or does Nvidia hardware simply choke on all DirectX games?

Odd thread crapping going on here.
