Half Life 2 prelim benchies with 5x.xx?

[Ruined]

A month or so ago Anand had an article with prelim unconfirmed benchies on HL2 with FX5950 vs 9800XT on 5x.xx drivers. Anyone have a link to that story or the benchmark?

it was in his pseudo-blog thing...

Anyone know anything about whatever happened to that HL2 benchmark that was supposed to be released? Ain't there even a couple of copies of it floating around in the wild somewhere? (I haven't found any, and I have LOOKED! :( )

[Dazz]

I created a thread about that a while back also...... where the hell is my HL2 benchmark program DAMN IT!!!

It disappeared into thin air with no explanation. Oh well. I'd rather they release a version that has maps with HDR lighting effects in it at this point.

Agreed.

the link on anadtech is wierd man
a geforce fx 5950 ultra do almost the same thing that 9800 xt ??:eek2:

Its not wierd fx 5950 ultra was running DX8 effects mouslty in they mixed mode :rolleyes: while ATI did DX9. :p

"Mixed mode" means they are doing mixed FP16/FP32 precision instead of constant FP32 precision all the time which would run incredibly slow on NV3x hardware. ATI does FP24 all the time, which is lower than Nvidia's FP32 in mixed mode but higher than their FP16 in mixed mode.

See. There are two kinds of "mixed modes." With regards to HL2, you are wrong in that it IS mixing DX8 and DX9 level shaders. Some people refer to the use of _pp flags as a sort of mixed mode, but that's not really mixed mode.

So yes. The NV cards are using mostly DX8 shaders and some DX9 shaders.

There are two mixed modes in HL2. One is DX9 and one is DX9/DX8.

See Ruined i was right so take that :spank: :tongue2: , for Nvidias sake they better not screw up with NV40 :rolleyes:

Uhh Theres a pp hint in a full DX 9.0 Mixed mode and a 1.4/2.0 Shader mode for FX cards? Is that what your sayen Stealth?

Yeah. AFAIK there is a mixed mode for the high end cards that uses full precision and partial precision. And there is another mixed mode for midrange cards like gfFX5600 that uses PS1.4/PS2.0.

I would hesitate to call the DX9 codepath a mixed mode. Sure, it uses _pp and can mix FP16 and full precision, but it doesn't necessarily mean that the card uses mixed precision (cards that don't support _pp).

I hesitate to called a codepath that might use mixed precision a true mixed mode simply because it isn't necessarily a mix of anything. Also, a mixed precision mode does not offer the enormous performance benefit of the DX8/9 real honest-to-God mixed mode. Weren't the original benchmarks showing the NV cards running the mixed mode about twice as fast as the DX9 codepath?

Yes, Shirley, I'm going to call the mixed precision mode the DX9 codepath from now on, and I will call the DX8/9 the mixed mode.

No. There were benchmarks of NV35 on the true DX9 codepath(full precision) versus the mixed precision codepath. The mixed precision codepath was a lot faster than the full precision codepath.

There were benchmarks of the NV31 using the DX9 mixed precision codepath versus using the DX8/9 codepath. NV35 however, was never ever benchmarked on the DX8/9 codepath.

We don't know how Valve will handle different codepaths, but I imagine cards that don't have multiple precisions like Volari and Radeon will not even have the option to run the mixed mode since there is no benefit.

Valve in their slides and review sites are calling the mixed precision mode the "mixed mode codepath" and are calling the full precision mode the "DX9 codepath."

AHHH CRAZY TERM MIXUP EXPLOSION.

Okay. I stand corrected. I never really paid that much attention to the HL2 benches anyway.
