ATI driver settings - 4850

[Chong Warrior]

Trying to save some chores of trying to find optimal settings by trail and error here. Having upgraded from an AGP 9800pro 128mb on 17" LCD to 4850 512mb on 24" LCD I needed the latest drivers and there's suddenly lots of new options available!

Had a quick play last night but even on a game like Civ IV with everything maxed out it couldn't hold a smooth 60fps, it was more like 45fps and a little jerky when scrolling around.

Resolution: 1920x1080
Anisotropic: 16x
Anti Aliasing: Lvl 8x samples 24x (edge effect)
Adaptive AA: Enabled
Catalyst AI: Standard
Mip-Map Level: Highest Quality

I know they're big asks in terms of IQ but it's only Civ IV, I'm not trying to run Crysis at that level What's the point in having the options if you can't even play chess with them?

So what are the real performance killers? Should Adaptive AA be disabled? Stick with Edge-Effect AA but toned down to 12x samples??

What are you guys using?

First thing I'd do is not use CCC, just install the standalone driver and get ati tray tools and for me I just leave all the af and aa stuff application controlled and performance set to max quality.

drop adaptive aa, if you still need more performance then at that res definitely drop aa to 12x, perhaps 8

I found that with adaptive use the performance setting as the quality one is a huge hit on fps. Also I found in certain games that edge detect for aa gives worse performance than 8x aa using box filtering so try that.

lol, dontcha just love it when everyone agrees and says the same thing

Will try dropping the adoptive and see what that's like.

@ liquidex, the only thing I don't like about high AA, especially with games like Civ IV is it makes things blurry. That's why I was messing with the edge effect but it does give a big hit on FPS...

 

[liquidex]

Ah I see. Most games I play are quite fast paced so I never stand still in one place long enough to look for the blur

only wide and narrow tent AA make things blurry. box and edge detect should be fine
