Cannot enable anti-aliasing?
 

I am playing the original Necrovision and cannot enable anti-aliasing through either the options menu (MSAA) or the drivers (Catalyst Control Center). I have tried 2x, 4x, 6x, 8x and there is no difference between any of the settings. I am using the most recent drivers, 11.1a. Here are my specs:

Windows 7 64-bit
6GB DDR3 RAM
Intel Core 2 Quad 3.00GHz
Radeon HD 6950 2GB

The game looks and runs fine otherwise. Is anyone managing to enable AA? Any help would be appreciated. Thanks.

EDIT: I have this problem on DX9 and DX10.

It sounds like a compatibility issue with the game rather than your hardware. The HD 6950 should certainly be capable of handling AA, but older games can sometimes ignore driver-forced anti-aliasing, especially when they use their own rendering method.

Since you've already tried both the in-game MSAA settings and forcing AA through Catalyst Control Center, I'd try creating a specific profile for NecroVisioN rather than changing the global settings. Make sure the profile is set to Override application settings for AA rather than “Enhance application settings.”

If that still doesn't work in either DX9 or DX10, there's a good chance the game simply isn't accepting the forced AA with those drivers. You could also try an older Catalyst driver, since 11.1a may have introduced or exposed a compatibility issue with the game.

Given that everything else is running normally, I wouldn't worry about the GPU or RAM. This looks much more like an old-game/driver interaction. Check out fnaf to know more information.
