5900 shows low fps than expected and also big performance hit w/ AA and AF in my favorite TW2003 demo version

my system is badly configuired? or TW2003 is coded like crap?
or 128MB of video memory is not enough to use 4AA on 1080*1024?

this is normal, on my ti4200 I take an even bigger hit with fsaa than you do!

try using performance AF. high AA/AF setting is not free, especially at high resolution, even the mighty r3xx lose 40 plus % of framerates easily at this setting.

4x FSAA has a big on on every NVIDIA card except the NV35. I would not recommend using 4x FSAA. I do recommend 2x FSAA, which should have a much lower hit than 4x and it looks almost as good.

Join the club Dude. I run fsaa and anisotropic in all my games. The first thing I noticed is despite the "on paper" power of the 5900 Ultra, it once again is a Nvidia issue. When the fsaa and anisotropic are cranked up, the performance hit is much higher then on the 9800 Pro.

I heard the fx cards eat the radeons without fsaa, but with fsaa the radeons are on top. Kinda makes me consider an fx5200 ultra cause those are faster without fsaa :) Perhaps in 2005 when the fx5200u goes for $50 ill get it for dx9 games then get a 9700 pro for $100 in 2007

Yes I encounter the same thing, I'm dissapointed about the fx5900's AF performance, though it looks somewhat better then on my R9800, in most games the performancehit is 50% ;(

First of all, TW2003 Demo is not coded for VRAM any larger than 128 MB cards.

Secondly, TW 2003 is not coded like "crap". The AA/AF modes will choke at 1280x1024x32 on a GF4 or a Radeon 9800 Pro because of the animated trees (especially at the course these pics are on). The animated trees are a HUGE drain on framerates. If you go to a desert course like Scottsdale, this issue is much less noticeable. Try playing with the Course settings in the Options Menu to see if you can find a sweet spot in performance. I never use AA in TW. I have used AF on my 4600, but I don't care for the performance hit with respect to the benefit.

I did not try TW2003 yesterday when I got to spend a few hours with a 5900 Ultra. There is a patch at EA that enables 256 MB cards to run TW2003, but 2003 is not specifically coded to take full advantage of the 256 MB cards. TW 2004 is being designed to take advantage of these larger amounts of VRAM. I don't have TW2003 installed anymore because I am devoting all my time to testing TW2004. TW2004 runs about the same (framerate-wise) on my 4600 compared to 2003 which speaks to the improvements in the game engine since there is alot more going on in the environment than in 2003.

Hope this helps explain what you are seeing...

In that case get a Ti4600, it is cheaper than a 5200FX, and beats it comfortably without AA/AF.

Huh? You heard wrong, they don't eat anything, AA/AF or not.
