5770 HD Sapphire - Bad Anti Aliasing?

Hey I recently purchased a 5770 HD Sapphire version.
Its running stable at 955/1400 at around 40C idle and 50C load.

But the problem is in games, the anti aliasing is really weird. The bigger objects like mountains etc look great, the character / weapon models are all nice. But things like thinner objects are all jaggedy, stuff like ropes, wires, thin shadows, those kind of things are all jagged and horrible looking no matter how much AA I have on .

I also have some bad shadows in certain games like BFBC2 and Just cause 2.

Games I'm running all look bad compared to the gameplay videos on youtube with the same card. I don't know why

I tried upgrading drivers already, didn't help at all. Forcing AA through ATT or CCC does nothing too.

My specs are like

Phenom II x4 955 black editon (Oc'ed at 4.1ghz]
ATI Radeon 5770 HD .
Gigabyte MA785GMT-UD2H Motherboard
650 Watt PSU
A fan cooler.
4 GB Kingston RAM DDR3

OS : Windows 7 64bit.


here are some screenshots in JC2

it looks better in the pictures, but ingame the shadows and lines flicker and jagger etc.

are you playing games at your monitor's native resolution?

Yeah I am.

Its a 1280 x 1024.

Its what I always select in the settings for games.

try the 5770 at factory settings, see if that helps

in fact you don't really need to OC that card for your resolution.

Yeah I tried that, it didn't work =/

I even tried reseting my BIOs settings too .

You cant just slap on some AA and think that will sort everything out. There are different settings for AA in the CCC that you should experiment with. Tent or Box, narrow or wide, edge detect. How many samples X2 or 4 or 8 etc. Then there is AAA or Adaptive AA. AF and AI, mip mapping and with all these settings you need to experiment to see what works for a game and what doesn't. Some games don't even support AA natively.
Take a look here
When I had a 1xxx series card I used ATI Tray Tools to tweak all sorts of things. These days I just go with the CCC.

SHawking: i just bought one too... cost me alot... although it can run almost all games at high details.. but everytime i put anti-aliasing 2x, 4x, etc.... my game quits... or gives a warning error....

and when i go to the catalys menu.. when i try to tweak the anti-aliasing low balance quality.. the program stop responding... just curious and i want to know if my video card is broken....
