ATI Catalyst 4.6 and Omega 2.5.51

ATI has released version 4.6 of its Catalyst driver suite for its Radeon range of products. We are also offering a link to the very highly regarded Omega version (2.5.51) of these drivers, for those of you who wish for a tweaked gaming experience.

Omega 2.5.51

Based on the official Catalyst 4.6 drivers.

- Updated the Omega version of RadLinker (1010), now Radlinker includes a new skin option and adds support for x800 overclocking.

- Added some tweaks for OLG. Enabled OGL Triple Buffer by default.

- Added support for MANY NEW Radeon cards, FireGL cards and Mobility chipsets.
ANY card should be supported now and the drivers will always install.

- Now the drivers should work a LOT better on laptops.

- Fixed FireGL card support, now it has full CP support and fully working OGL.

- Changed the installer graphics.

- Added a new option in the installer to select a faster OLG driver instead of just using the latest one, this driver runs Counter Strike like butter. Important note: The special OGL driver will NOT work on x800 cards. Many thanks to NGO for their input, this was their idea.

- The package keeps growing in size, the drivers will keep being distributed in compressed CAB format to save some bandwidth, it must be decompressed using one of these tools (latest version): WinAce, WinRAR or WinZip. Then run the extracted file to start installation of the drivers.

Catalyst 4.6

This version of the drivers includes several X800 improvements and fixes for games such as Call of Duty, Wolfenstein - Enemy Territory, Star Trek - Elite Force II, Serious Sam, Return to Castle Wolfenstein and Quake III Arena.

The full list of foxes and improvements is as follows:

Performance Improvements

-Pixel Shader compiler improvements bring significant performance gains to PS 2.0 applications such as Halo (2-3%), Tomb Raider (4-5%) and Mother Nature (4-5%).
-ShaderMark 2 shows numerous gains in the 3-6% range. The High Dynamic Range scenes in ShaderMark (Tests 20 & 21) gain 10-15%.
-RADEON X800 driver tuning improves performance for several Vertex-Shader-heavy tests. For example, Battle of Proxycon, Troll's Lair and Mother Nature gain 9-15% on the RADEON X800 PRO.
-Improvements in our surface allocation and texture management code have increased performance for resource-challenged cases. Re-Volt scores improve 25% at 1600x1200 across several RADEON configurations. ShaderMark Test 14 (Veined Marble) improves dramatically (up 380% at 1600x1200) on some 256MB products.
-Improvements in OpenGL driver efficiency bring numerous small gains (1-3%) in Call of Duty, Wolfenstein - Enemy Territory, Star Trek - Elite Force II, Serious Sam, Return to Castle Wolfenstein and Quake III Arena.
-X800 memory tuning improves Anti-Aliasing performance in a number of games and benchmarks. For example, at 4xAA, 3DMark2001 gains 4-7%, UT2003 Antalus and Asbestos
-Flybys improve 2-7%, and the CodeCreatures score rises 15%.

Resolved CATALYST Driver Issues

-Display corruption is no longer seen when rotating the primary desktop 90 degrees or 180 degrees under Windows 2000 with extended desktop enabled

-Playing a DVD with DXVA enabled and attempting to rotate the display 90 degrees no longer results in the operating system failing to respond
-Moving an OpenGL window around the Windows desktop no longer results in the operating system intermittently failing to respond

Resolved Game Issues

-While playing the game Halo, under certain conditions, images that should be hidden behind solid foreground objects are no longer showing through
-Starting a game of Splinter Cell Pandora Tomorrow under Windows XP with an ATI RADEON 9000 PRO installed and the display set to 1024x768 and the graphics quality set to high no longer results in flickering textures
-Display corruption is no longer seen when using particular air craft in "Century of Flight" games found in Flight Simulator 2004
-Textures are now applied correctly in the game Silent Storm when setting the resolution to 1024x768 32bpp and the quality option set to high
-Enabling AF to 8x and running the game Battlefield Vietnam with the graphics set to high and the display set to 1280x1024 32bpp no longer results in display corruption being seen at a certain point of the game
-The display menu for the game 4x4 EVO 2 is now available when the rotation option is used to set the display to 180 degrees
-Circular grid corruption is no longer seen when launching World Fables under Windows XP with Anti-Aliasing enabled at 4X
-The Windows XP operating system no longer intermittently fails to respond when restarting the game Homeworld 2
-Adobe Gamma and other colour calibration software now have the ability to adjust their independent gamma values. Note: In certain situations when closing the application, the default desktop gamma is not restored.

ATI Catalyst 4.6 and Omega 2.5.51

Hey does anyone know how to remove the checkerboard artifacts that almost cover my screen when playing games using the omega softmodded drivers? It's all well and good opening the extra 4 pipelines on my Radeon 9800SE, with the nice big fps increase, but what can I do to remove the f**kups?

ATI Catalyst 4.6 and Omega 2.5.51

YOU HAVE DAMAGED PIPES. If you get the checkerboards that is that means u have damaged pipes. This is the real reason those cards were disabled they were actual 9800 pro cards but because they didnt pass final tests and since most of the beggining pipes worked they choose to make all damaged 9800pros 9800se cards instead of getting rid of the units... Some people are lucky and got cards from saphire that really had 9800pros but were turned into 9800se cards because of a shortage or overstock.. I red about this ages ago..

ATI Catalyst 4.6 and Omega 2.5.51

the main reason games crash are due to your cpu overheating and or video card getting too hot but usually the cpu. I dont know how many times ive seen people overclock there cpu and show them that underclocking the cpu solves all there problems. Not always but give that a try if u have overclocked in the bios.. Dropping to desktop or constant rebooting is usually due to heating issues these days or lack of power when trying to overclock...

ATI Catalyst 4.6 and Omega 2.5.51

Why do u bitches have problems with the new driva? ' cause u're f**kin' stupid! ..u have no idea of how a computer works! ...u just know how to play a stupyd game and if it doesn't run, u cry like a little schoolgirl!!And for these who are pissd off about ATI: Make it better!! Its a wonder that u little f**kers are able to turn on u're computas!

ATI Catalyst 4.6 and Omega 2.5.51

ok my radeon 9500 had horrible checkerboard patterns all over various colors on the screen, low-graphic games like half-life stopped working properly, and when i uninstalled this driver and re-installed the old one, windows refused to run. Nice one, ati, nice of you to create a big mess that I will have to fix.Oh well, i don't reccomend anybody who isn't having any graphic problems to waste their time with this catalyst, as it is obviously incomplete (even though it has great features)

OK ATI FANS...THE TRUTH HURTSSOMEBODY HAVE SCORED 100,225 IN AQUAMARK 3 BY USING A 6800Ultra.X800XT?IMPOSSIBLE SINCE IT IS ALREADY BEING PUSHED TO THE LIMIT."SirLeto: What are your favourite hardware components right now?Shamino: The 6800 Ultra and the P4 3.4EESirLeto: Which aquamark3 score do you predict for the intel/nvidia class in six month from now?Shamino: 120K provided card voltage can weilded properly, together with 1.6ns ramsSirLeto: Which cpu/gpu combination has the most potential right now from your point of view?Shamino: FX 53 with 6800 Ultra, their power have not yet been fully unleashed yet."Yes,6800 still have something left to offer..remember the low clockspeed?Nvidia:400-450MHz,ATI:525MHz!

ATI Catalyst 4.6 and Omega 2.5.51

Thanks, I guess u are right! I shouldn't have installed new drivers since I had no problem with the old ones! But, us gamers are always striving for more fps. Even 2-3% improval in benchmark tests like 3dMark 03 can make us crack a smile. Thanks anyway. I will try the 4.6 and if im not satisfied ill re-install 4.3

DOOM3 & DIRECTX 9.0c WILL BE OUT SOON! FARCRY PATCH 1.1 IS OUT! BUY AN NVIDIA!Nvidia and its partners will be overjoyed to hear that Doom 3 will finally be available on the 3rd of August.This game is very important for Nvidia since this is where its rendering marchitecture will actually pay off. From NV30 upwards all Nvidia GPUs are able to render texture values without Z or Color information. The NV40, Geforce 6800 series has full 16 pipelines that can process one texture and can render as much as 32 textures without Z or Color info.This means that in Doom 3, Nvidia's tech is likely to be much faster then ATI's R420. As much as 50 per cent faster!Plus DirectX 9.0c will be bundled with Windows XP Service Pack 2 which will be officially released by Microsoft anytime soon. This will also indeed be a big advantage for Nvidia.The people that are getting MSDN packages from Microsoft are already able to download it.All drivers from 61.34 have support for Shaders 3.0 which again is a big advantage for Nvidia.Ubisoft also recently released the new 1.1 patch for FarCry. Patch 1.1 improves shader speed up to two times for Nvidia Geforce FX cards on very high settings and that now works with Nvidia drivers. NV40 support and some other fixes have been added, but most importantly support for the PS3.0 shader profile.Shader 3.0 games might arrive sooner then we all expected since Nvidia's $20 million can be very persuasive and help developers and especially publishers to upgrade their games from Shader 2.0 to 3.0As for Half-Life 2, the $6 million later and over a year delayed Half Life 2 is still not 100% ready even with their August deadline. Radeon 9800XT and 9600XT customers still have to cross their fingers.

ATI went the smart route again. They saved 60 million transistors for a technology that won't see major use until the next gen chips come out. here is only 2 games that are going to support this feature. And those two games are not DOOM3 and HL2. They are average games. And i have just read those early reports of the patch at those sites, only 10% increase to put it on level with the XT800 is not exactly making me jump for joy. Considering also only one game supports some of the features.Just a little tid-bit......"One of the main features of pixel shader 3.0 is that is supports dynamic branching (also called data dependent branching), something that nVidia of course makes a big deal about. This demo however shows a way to implement dynamic branching without pixel shader 3.0, using basic graphics functionality such as alpha testing and stencil testing. Not only is it doable, but also gives every bit of the performance of real dynamic branching."-hardocp.com-

ATI Catalyst 4.6 and Omega 2.5.51

Actually they do. At least ATI does not claim extrodanairy increases in performance in games like Nvidia does. Increases like 70% and over across the board in the most popular games. When a gpu company does that, you know it's bullshit.

ATI Catalyst 4.6 and Omega 2.5.51

nice driver.... NOT!i never hade trobles whit ati drivers and the always work.. but this 1.. i install it and my cpu completly crashes.. i need to reboot my cpu whit the last good working settings... only than i completly lost my ati driver.. so i installed version 4.4 again.. that 1 works fine though...

ATI Catalyst 4.6 and Omega 2.5.51

Very impressed with the new drivers. I have a Radeon X800 Pro and 3Ghz P4; benchmarks in 3DMark went from 8390 to 8961 compared to the 4.5's. The only games installed in my system currently are FarCry, Hitman:Contracts, and UT2004; all run glitch free and smoothly. Another stable driver from ATI.
