I currently have a asus v9999 nvidia geforce 6800gt 128mb Whenever I run say battlefield 2 or black and white 2 or half life 2, I can run all settings completely maxed out, but as soon as I turn on anti aliasing just a little bit my performance goes right down the drain. Why is this? Shouldnt my video card at least be able to hand a small amount, it is a 6800 after all.

I had the same trouble with BF2. You have to lower some of the setting down to med but keep some at high then turn on AA and it will work fine. But if you want AA on and every thing else maxed out then you will have to go to a 7800gt or gtx. HL2 should run perfect with every single thing maxed out, I have no trouble.

At it's most basic level, AA works by drawing each frame multiple times and superimposing them on top of each other. That, in a nutshell, is why GPU-limited games take such a huge performance hit with AA enabled whereas CPU-limited games don't see much of a drop at all.

BF2, as you might surmise, is very GPU-intensive, as most bleeding-edge engines are.

Insted of running AA jusy Bump your resloution up to either 1280x1024 or 1600x1200.

I only like to use AA at lower reslotions like 1024x768, there you get a good balance between performance and image quality

That works better i think. For me in HL2 and CSS I can run it in 1280x1024 and it goes heaps better than in 800x600 with 2x or 4x AA. On a 17" screen at 1280 or higher AA doesn't really make a difference unless you have it maxed anyway.

I see no point in having AA at all unless you have a big monitor that looks like 800x600 when its in 1600x1200.
