ID recommends Geforce FX for doom III
- Thread starter DarkKnight
- Start date
This surprises you? Carmack has said all along it will run faster on nVidia.
Now we just have to wait for our nV40s.

but dont they have to reduce the quality on the FX cards? I thought it only ran faster because the graphical quality on ATI cards was better cause of Nvidia's hardware limitations (dont remember what it was).
Actually, it probably has more to do with the fact that Nvidia cards do better in OpenGL.
Oh and, yeah, Id Software has always been fans of fat sacks of cash money.

If Nvidia's going to 4x1 chips and 8x1 and 16x1 as many are suggesting then this goes out the window. The basis of the GF FX being faster was that Doom III uses older style rendering and therefore benefits from multi-texturing cards like the 4x2 GF FX 5900.
Newer DX9 games like HL2 appear to benefit more from ATi's larger number of pipelines and single texturing.

i wonder how much nvidia paid id software for that
i do think it will run just fine on nv3x hardware, but it's all marekting hype. doom will have custom "backend" that will use the lower precisions on the nv3x hardware. we'll just have to see there's an IQ impact or not. at any rate, aren't you guys tired of all the doom 3 hype yet? it's been 3 years almost since we first saw it running on a g4 mac and geforce3 at the mac expo...<yawn>

ATI are going to get bitch slaped! in the next gen videocard race! ... 16x1 Pipelines for NV40 and it also will be packaged with a Retail COPY on Doom3 ... NOT a stupid Coupon.
Exactly. This one has 'marketing" written all over it people. Don't get me wrong - all the Benchies seem to show that GFFX cards ARE better for Doom 3, but this is still about financial gain, not educating the customer. You don't see "Nvidia Reccomends ATI hardware to run the Dawn Demo" stickers about for some odd reason...
No surprise here. It had been said all along that nvidia hardware would be faster, and the benchmarks tend to support that. I'm sure nvidia did pay a nice sum though to make sure id would recommend it and make it a "way it's meant to be played" game.
ATI isnt gonna put out a new card, their company is going to shutdown before then. That would definately be a sign of God in my eyes. lol
Dont you like competition???? The fight between Ati and Nvidia can only be a good thing for gamers.
This is hilarious. It is a sticker recommendation which means Nvidia will put a "recommended by id for Doom3" sticker on all the FX cards sitting on the shelf.
This is not a recommendation of some future chip.
They are saying the FX5200 will run it better than a 9800Pro or 9800XT. You buying that? LOL

It was only a rumor that ATi leaked it, and another rumor said it wasnt. Fact is, we dont know who did it.
The FX's had to have their own path written. When playing in the standard ARB path, the Radeons are much faster. So it Doom3, and HL2, the FX's had to have their own path written in the code to get better performance... Pretty sad to me.

It's been fairly clear the FX line was architected with an eye toward Doom 3. FX12, double stencil ops per clock--where's the mystery? This actually seems to be a fair representation, for a change. Even though ATi should be able to keep up, the initial benchmarks showed them eating nV's dust. It'll be interesting to see if ATi's drivers were the culprit, or if nV actually has a natural advantage in D3.
The advantage that Nv has over ATi is that they could lower their precision to run faster. In OpenGL precision isn't really that important.
Not quite. nVidia gave Carmack all the explicit features and extensions he wanted for DooM3 and he used them. Carmack has been talking about the DooM3 engine since back in the GeForce1 days and you can go check his quotes from then yourself. He wanted 64bit color(AKA FP16) he wanted really fast register combiner ops and he wanted loads of stencil op power- the FX architecture with nV's proprietary extensions.
When playing the ARB2 path the big difference for the nV parts in terms of performance is that they are running in FP32 vs FP16(talking about the NV35 parts here). ATi's boards are running a 'lower quality' setting by using FP24. Carmack says that there is no discernable quality difference between FP16, FP24 and FP32 for DooM3. You have to say Carmack is wrong or say that ATi is faster running medium quality then nVidia is running high quality to validate the above statement.
Pete-
I'm interested in why you think that? If anything, I'd say ATi shouldn't be able to keep up in DooM3 unless nVidia has some driver issues. Not a slam on ATi at all, they decided that PS2.0 was the way to go when nV focused more effort on the D3 direction. I'd personally be thrilled if my R9800Pro could keep up with a FX5900U at DooM3, but I find that extremely unlikely.
Ben, I mean that ATi can process just as many colorless pixels (zixels ) as nVidia per clock (eight in the high end, four in the midrange). ATi's lower clock speeds at the high end should mean they'll be slower, but their midrange cards should do fine--provided memory speed/access isn't the limiting factor, where nV has a decided advantage. I'm oversimplifying the hardware, no doubt, so if nV's dominance over ATi in D3 remains unchanged, there must be more than mere clock speeds and zixels/s at play.
Vian, nV's advantage isn't lower precision, it seems to be mainly higher clock speeds (both core and memory, and particularly with the first FX generation, NV34/31/30). And I can't think of something inherent in OGL that makes higher precision less important. It's the engine that determines what precision to use, and D3 apparently can make do with FX12 just as well as with FP32 (according to JC, anyway).

LOL Reever. We have to assume Carmack is "right" because it's his program. Unless you'd rather take a PR guy at ATI's word for it?

Probably just as much as ATI paid Valve.
