It may be a problem with more than your graphics card. Post your system specs here , and I will see what problems you may be having there. Also try turing off un-needed background processes and programs that are running at the same time you are playing Halo PC. I will help you figure out whats lagging your game, if you need to upgrade, or just build a whole new system.
