Ati promises Doom3 performance Boost!
- Thread starter gameboyzz
- Start date
Its just like saying a Trident XP4 taking over a Ti 4200. Reviews have showed the X800 Pro losing to the GT big time at high resolution. Or lets say a difference of over 10 fps. Thats huge.
May be ATI is planning to unleash the first time DUAL Drivers, when Playing Doom III, one driver takes over, when playing everything else, the other Driver takes over.
That by the way was just my brain feeling tired a bit

The X800 Pro has 12 pipelines to the GT's 16, so it's going to be slower pretty much no matter what.
On the subject, this is good talk from ATI; hopefully they can back it up. I wouldn't expect anything to come out in the immediate future - if a marked (10% +) improvement can be made to the OpenGL drivers, I would expect it to take a couple of months.

The 9500pro was 8 pipelines and was slower than the 5950u which was 4 pipelines.
Pipelines arent the end all be all and in fact the x800pro outpaces the GT in some games because of its clockspeed advantage.

You're not familiar with the situation at hand here, so it's no surprise that you're talking pretty much out your butt here.
With the Doom 3 tech, pipelines pretty much ARE the end all be all. Do a little reading on how the lighting in the game is rendered and you'll see why. Basically, pipelines get a two for one deal when doing stencil shadowing - effectively allowing NV40 cores with 16 pipelines render up to 32 pixels per clock.
Even if ATi's 12 pipe X800pros were functioning as efficiently as NV's cards (which they don't, mainly because ATi's OpenGL support is poop), you're still looking at 24 pixels, tops.
Stencil shadows put a premium on the number of pipelines you're packing when it comes to performance.

Why would it double the performance of a Pro. A Pro has 12 pipes a GT has 16. Where is the doubling there? I certainly see the 16 pipe cards doubling performance of the last gen 8 pipe cards.
Also the 9500 Pro did not have 8 pipes unless you did that wonderful little mod that turned it into a 9700Pro. Do remember that the 5950Ultra was 8 pipes in some situations. When multitexturing for instance it was 8. Also it was clocked much higher than the 9500Pro.

When Nvidia was poor in the DX9 performance area with the 5xxx series, they did everything they could to offer better performance with new driver releases. They also fubared the hell out of the image quality in the process to gain fps. I am seeing a pattern here that ATI will continue only this time its OpenGL. ATI will most certainly get better performance in fps, but in order for them to compete with nvidia, I feel that they will have to sacrifice some goodies to get there. IMHO. Its kind of like the flip side of the optimizations coin and its not flipped onto the ATI side.

Not for nothing, but can you please read my post again carefully. I said 12 pipe 6800 shoudl have double the performance in DoomIII if the 2 pixel per pipeline is legit using the Z-buffer deal. But it does not and will not have anywhere near double the performance of a X800pro.

hmm...ATI STRIKES BACK!!!! Ati tryin to get jiggy with OGL after all this time it seems. Nvidia is singing the "anything u can do, i can do better" song rite about now. if ATI figures out a way to manipulate doom3's performance, Nvidia will follow up on it. Perhaps shader model 3.0 like the farcry improvments? Why cant they do some of that Radeon 9700 magic they did back then? that was an insane card for its time, probably will play doomIII fine. I believe the X800 lost the fight before it even started, ive never seen an optomized for ati logo. ive only seen Nvidia, the way its meant to be played. well ATI, u got played...
stupid side thought....Why did these manufacturers pick model numbers that run out so quickly? after they reached the 9800 they are like....hmm....10,000 anyone? NONONO ADD AN X EVERYONE LOVES X BOX!!! Shut up, its the R500 core thats in the xbox, shuda saved it, woulda worked out fine.
and what about nvidia? gonna launch a 7000 card after the 6800? i have one...if ya know what i mean...

"There were no really significant games last year which used Open GL"
This is why there has been no driver rewrite I suppose. And correct me if I am wrong, but aren't the Unreal engines directx?

yes unreal engines always have been, and always will be, directX.
is unreal engine 3 9.0C or opted for 10?

And we are expected to believe that they will get something out soon..? It's not exactly like Doom3 snuck up on us. It was showcased at E3 2002, 2003, and 2004, and I've heard it called the "most anticipated PC game" on more than one occasion. I'm also quite sure that ATi knew that is was going to be an OpenGL game, but yet they still didn't bother to touch their OpenGL driver for almost a year. Kinda odd they would wait until a week before the game launches to to start reworking drivers that have been dormant for almost a year. I don't think anyone was surprised by the results of most of the Doom3 benchmarks.
It has nothing to do with performance doubling - only doubling the number of pixels rendered per clock. This results in a hefty boost to performance, but games aren't rendered in pixels - they're rendered in frames, which pixels go in to. Having faster pixel rendering will definitely help FPS, but FPS increase and pixel render speed are not directly correlated.
That's bullsh*t
The original Unreal Engine was GLIDE ONLY. Direct3D and OpenGL support was added in patches. Unreal Tournament shifted the engine's rendering focus over to Direct3D, but it was still basically a patch-together hack. Unreal Engine 2 was built from the ground up to take advantage of Direct3D, but it still supports OpenGL rendering.
Unreal Engine 3 will be built with DX9 targeted as the minimum spec, and will support OpenGL rendering.
