NVIDIA's GeForce 8800 (G80): GPUs Re-architected for DirectX 10

F.E.A.R. Performance
With the latest 1.08 patch, F.E.A.R. has gained multi-core support, potentially using even up to quad core CPUs in order to deliver improved performance. We were able to confirm a performance increase with Core 2 Duo, and we will try to take a look at whether or not Core 2 Quad helps in the near future. Either way, this means that we should now be completely GPU limited in F.E.A.R. testing.
The new GeForce 8800 GTX card still manages to come out faster than the competition, but this time a single 8800 GTX is not able to surpass the performance of dual X1950 XTX cards (or 7900 GTX SLI for that matter). Quad SLI also manages to make a decent showing in this particular benchmark, coming in second place except at the highest resolution. Meanwhile, GeForce 8800 GTS doesn't fare as well, only managing to tie the X1950 XTX for performance, and it even loses that battle at 2560x1600. F.E.A.R. is a game that can use a lot of memory bandwidth, so it's likely that the 2GHz GDDR4 memory on the X1950 XTX is helping out.
If money isn't a concern, 8800 GTX SLI will finally allow you to play F.E.A.R. at 2560x1600 with 4xAA without dropping below 30 FPS. Is that really necessary? Probably not to most people, but if a similar situation exists in other games it becomes a bit more feasible.

You can just use the program DX Tweaker to enable Triple Buffering in any D3D game and use your VSYNC with negligable performance impact. So you can play with your VSYNC, a high-res and AA as well. :)aweigh - Friday, November 10, 2006 - link
I'm gonna buy an 88 specifically to use 4x4 SuperSampling in games. Why bother with MSAA with a card like that?DerekWilson - Friday, November 10, 2006 - link
Supersampling can make textures blurry -- especially very detailed textures.And the impact will be much greater with the use of longer more detailed pixel shaders (as the shaders must be evaluated at every sub-pixel in supersample).
I think transparency / adaptive AA are enough.
On your previous comment, I don't think we're to the point where we can hit triple buffering, vsync, high levels of AA AND high resolution (2560x1600) without some input lag (triple buffering plus vsync with framerates less than your refresh rate can cause problems).
If you're talking about enabling all these options on a lower resolution lcd panel, then I can definitely see that as a good use of the hardware. And it might be interesting to look at more numbers with these type of options enabled.
Thanks for the suggestion.

I never knew that about SuperSampling. Is it something similar to Quincux blurring? And would using a negative LOD via RivaTuner/nHancer counteract the effect?How about NVIDIA's Digital Sharpness setting in Color Correction? I've found a smidge of sharpening can do wonders to improve overall clarity.
By the way, when you said Adaptive AA, were you referring to ATI cards?

Derek,Saw your comment regarding the rationale for the test resolution, while I understand your reasoning now, it still begs the question how many of your readers have 30" LCD flat panels?

There might not be many out there right now, but it's still the right test platform for G80. We did test down to 1600x1200, so people do have information if they need it.But it speaks to who should own an 8800 GTX right now. It doesn't make sense to spend that much money on a part if you aren't going to get anything out of it with your 1280x1024 panel.
Owners of a 2560x1600 panel will want an 8800 GTX. Owners of an 8800 GTX will want a 2560x1600 panel. Smooth framerates with the ability to enable 4xAA in every game that allowed it is reason enough. People without a 2560x1600 panel should probably wait until prices come down on the 8800 GTX or until games that are able to push the 8800 GTX harder to buy the card.

Derek,A follow up to testing resolutions, the FPS numbers we see in your articles, are they maximum, minimum or average?

Who the heck runs 2560x1600? At 4XAA? Come on guys, real world benchmarks please!DerekWilson - Friday, November 10, 2006 - link
we did:1600x1200, 1920x1440, and even 1280x1024 in Oblivion
