hmmm... vyzera to vcelku slusne... ale 35FPS vonku je dost malo, a hlavne ked tam niesu ziadne MPC a niejaka poriadna scena s vybuchmi a pod. efektami...

AMD/ATI - R6xx - Dovod velkych prepadov vykonu s MSAA odhaleny ?! - len 2xMSAA za takt !

Anyway, no need to respond. You're right in that we should keep it all technical here.

Okay.

What about with colour and Z both enabled? Or is that limited by Z, like previous generations? I was kind of hoping that with a 512-bit bus you'd try to maintain 16 pixels per clock with 4xAA, especially with NVidia pushing 96 samples per clock, but I guess I was just dreaming.

The Z is 32 frags per cycle, regardless of AA mode. That's 2x before in non-AA. I don't disagree that I would of liked to have 4xAA for free, but it's 2xAA for "free".

The last ROP question I have is whether you allow AA with 32-bit per channel rendering. It may be excessive for HDR, but it's nice for variance shadow mapping.

Yes.

nazdar kluci odporucate mi do crosfire 2900xt ake mate skusenosti

[crux2005]

pokial maju ovladace profil na danu hru, tak funguje CF dobre, ~ +80% vykonu, ak nie je scena CPU limitovana

KeD nie, je to "bieda". Treba cakat na novsie ovladace, nakolko si profil nevies vyrobit ako v pripade SLi
