HD4890 only supports 8x AA, whereas 8800GTX supports up to 16x? Why is this?

[DementNeo]

Sorry to ask here, but Google didn't seem to know what I was on about (maybe I tried the wrong queries), but shouldn't the more recent and [B][I]arguably[/I][/B] more powerful 4890 support the same stuff? Is there anyway I can sort this out, and does everyone get this "problem"? It's not like I need it, but some games run at full speed, and I might as well throw my extra unused FPS on something, you know?

What resolution are you running at?

16xCSAA and 8xMSAA aren't the same. This is probably what you're seeing.

Yeah well, for a real world example HL2 only goes up to 8x, on my old card it went up to 16x (8600GT)

Might have said CSAA next to it, but I don't recall...

[damnatus]

sorry for offtop, but why you need more than 4x ?

[Risonhighmer]

What's the difference between CSAA and MSAA?

I don't, but read the OP, my monitor is only 60Hz so anything over 60FPS is wasted on me

It said CS I just checked, is that something nVidia supports but ATI doesn't then?

Quite a lot by the looks of things!

One works by Multisampling and the other works by Coverage Sampling.

Yeah just looked it up. So I'm not missing out on much, right?
