Default Re: 5800U walks tall on Doom3

New drivers are still making the FX series perform better. I think, somehow by making the 6800 perform better in the driver, we get performance benefits too. It could be that nVidia is still working on improving the FX series? We do get a lot of the same IQ options as the 6800 (i.e. High Quality, Tri Opts, Aniso Opts, etc) which older cards simply don't have in the control panel.

What would happen in a perfect world is id would release the nV30 path as a patch, and nV3x owners could get a HUGE increase, albeit at partial precision.

Why do I say this? Consider:
http://www.anandtech.com/showdoc.aspx?i=1821&p=22

Hmmm. Last year, 95fps for a 5800Ultra at 10X7 med quality, on a P4 3GHz.

This year, I get 50.4 fps on at those settings on a A64 3000+?! Even if it's a different demo, that's half the performance. Where did it go?

it's a different demo Rollo, different demos give different benches. also, all the partial precision was put into the arb2 path so the nv30 path would just be redundant.

I agree on the different demo part.

I don't remember reading about the partial precision being put into the path nV3Xs now run though, just the nV10 and 20? Do you have links?

I remember Carmack saying he dropped the nV30 path and went to ARB2:
http://www.shacknews.com/docs/press/..._carmackplan.x
but not that he incorporated the nV30 features into ARB2? I'm not a programmer, but I would think this would change the definition of ARB2 and make it vendor specific again?

What happened with the 9800Pro now being as fast as the 5900U would seem to support that the 5900U is running ARB2, which it can't run as fast as nV30 path?

Please correct me if I'm wrong, don't want to be unenlightened.

Carmack's .plan which you link to is not talking about dropping the nv30 path he did that much later. in your link he is talking about dropping vender specific vertex programs since they weren't needed with the new arb extension.

as for the 9800pro being as fast as the 5900u, that is because the 5900u does get the benefit of using reduced precision in the arb2 path like it once needed the nv30 path to do. look back at that link you posted to see how things once were with the arb2 path:

Quote:
The NV30 runs the ARB2 path MUCH slower than the NV30 path.
Half the speed at the moment. This is unfortunate, because when you do an
exact, apples-to-apples comparison using exactly the same API, the R300 looks
twice as fast, but when you use the vendor-specific paths, the NV30 wins.
but adding partial precision to the arb2 path doesn't make it vender specific, it just lets cards which can benefit from reduced precision do so. doom3 doesn't use any advanced shaders which really require full precsision, so there is hardly reason not to let cards which can benefit from it do so.

another 5800u user chiming in.. i've been fairly satisfied with this card, and when i made the move to a 2500-m to get near 2.4ghz it helped out alot.. at any rate i get good performance in doom3 at about 58fps on 800x high quality with the 65.xx drivers. with the 56.72's i was getting 42fps.

2500-m @ 12x195mhz
chaintech 7njs
crucial pc2100 @ 132mhz

i'm sure getting new memory and running in sync would help even more but money doesn't grow on trees yet.

And the way things are going, you'll need to spend your computer upgrade money on those $50 dollar gas fill ups
