Wanted to share something that has helped my computer run AH.
Scenario:
No matter how low I set the AH graphic settings and tweaked the windows processes there was a kind of skipping or slow stuttering going on while flying offline or online (even does it with anti-aliasing disabled).
Very noticeable in game when near the ground or other planes.
Followed the AH forum recommended settings for Catalyst Control Center (CCC).
Enabling MLAA in CCC eliminated the skipping effect as long as game graphics weren't set too high.
This has vastly improved my gameplay online.
Specs:
Windows 8.0 64 (skipping problem also occurred in Win 7 64)
Graphics - ASUS Radeon HD7750 1GB GDDR5
CPU - AMD Phenom II X4 965 3.4GHz

Monitor - Samsung LCD TV 32" 1360x768@60Hz native pc input with game mode enabled to reduce lag
