Hello all,

I recently got hold of an ATi 4670 following my 8800GT's unfortunate death :(

Anyway, on games (including TR:A, TR:L and CNC3) the graphic levels don't go as high as they did on my 8800! E.g. I can run with a max 4x AA on the 4670, but on the 8800 I could run 16xAA.

Is this normal for ATi cards, or is it a setting or something?

Cheers!

Ah right, is it the graphics won't be as good as the nvidia then? Or just that lower AA on ATi cards matches that of Nvidia higher AA?

No its not normal.
The ATI card you have is low end & with only a 128bit interface you will have no chance of 16 AA.

While your GTS was mid range & had a much bigger bus.

I thought he meant he physically couldnt set 16xAA, which i thought was normal, as only Nvidia cards have that sort of setting?

If you use wide-tent you get 16x samples AA and Edge-Detect has 24x samples AA. You can also get 12x with box. Through the CCC.

Yeah, i can set 16x AA in the CCC, just in games, such as CNC3 i can go to 'level 8 AA" max. On Tomb Raider's i can go to a max of 4x, there just isn't an option for 16x AA, just strange as my 8600GT i had quite a while back could run with 16x AA.

Even my old 8800GTX could not handle 16xAA on TRA + C&C3 without major slowdown for me. Your card can probably only do 4xAA as its a low end model.

ATI handle AA differently to NV cards so 4xAA with Edge Detect selected in CCC = 12xAA. 8xAA with Edge Detect selected in CCC=24xAA.
