Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
0.5 TFlops and not just with MAD instructions... well thats easy with G80 and "future driver release" (hopefully coming soon) :)

Nope. The reason is not a super-sampling mode.
Yes, it is possible.
Yes and no...
This texture sampling is based on lod sampling and filtering in(side) fragment program (a.k.a. pixel shader). Basically, it just fetch two lod samples (texture lookups) with different bias values and...
Well ATI's HQAF is not fully angle-independent but _less_ angle-dependent than NV's AF :)
The "less" angle-dependent anisotropic filtering can be done also on G7x (and NV4x) gpu with fragment programs/shaders (OpenGL or D3D). The performance hit you'll get is only like ~1 fps (depends on the...
Yeah... well in my opinion AA is pretty useless with high resolutions (16x12 or higher).
Btw. MSAA doesn't work with GRAW and BIA (even on ATI cards) :)
These are my "Q vs HQ" results. Optimizations are disabled manually and after that HQ is set.
System: A64 3200+ @ 2500 MHz, 2GB RAM, single 7900GTX (740/1900), ForceWare 91.31
Settings: 16x12 + AA 4x/AF 16x + game settings maxed
Doom 3 (ogl) - HQ 92,0 fps vs Q 94,7 fps - ~3%
Quake 4...
Kinda "AA" + HDR (better than nothing) is also possible with G70 and NV40 series cards....

The same goes for ATI - e.g. below is screenshot from confidental ATI presentation (pdf) for developers...

Have fun guys... NVIDIA sucks and ATI blows :)
OpenGL got 35% (more like 15-35%) boost on x1800 series = only when AA is enabled (very small gains with AF). Without AA the generic OpenGL performance is still bad on x1800 series.
NVIDIA "addict" heheheh nice complain... I'm just pointing out that there are some Quake 4 quality issues on ATI cards with newer drivers (mostly CatAI enabled). actually I meant that this "bug" is 16bit color depth bug probably in the alpha textures.... wonder why? Correct me if I am wrong, but...
