The ATI Radeon 5XXX Thread

[saaya]

I was talking about the small differences in AF IQ between RV870's near perfect angle independent AF algorithm vs Nvidia's.

Just like you cannot tell the differences between pre-RV870 AF vs post-G80 AF. The difference in IQ is there but hard to tell without still shots and zoom.

i see loads of flickering in several diferent angles with g92 and g200 based vgas as well as rv6 and rv7 based cards... there is no big diference between them...

the easiest way to spot it is warcraft3 since you got all kinds of angles towards the camera there since they use few polygones... in modern monster triangle games its harder to reproduce since the angles vary a lot... but theres no game where i havent noticed texture flickering on the floor and walls yet when moving along them...

Did you ever compare Nvs and atis af?Nvs HQ AF is much less flickering than Atis AF since G80. I'm hoping we'll see the same with Atis newer af and not only a better af flower. Flickering on R600 and their derivates is really the bigger problem than non-angle independant af.

set everything to max quality and tried diferent settings one at a time... its slightly better on nvidia vs ati... but no big diference...

ATI's "high-quality AF" setting suffers from flickering, the normal setting does not (kind of the opposite of NVIDIA's situation).

On another note, I had an interesting thought about the story from Fudzilla mentioning that NVIDIA is confident that G300 will beat the 5870: This statement is coming from the same company that said their previous generation products were faster just because they support PhysX!

it flickers with any setting, even the most blurry unsharp one... its just less... but thats a terrible compromise, blurry textures so they dont flicker? thats like pouring a drop of lemon juice in each eye before gaming so you dont notice the lack of anti aliasing in some hdr games
