Im not sure but i think i might have found a way to reduce the lag you get in halo2 vista by quite a considerible amount.
goto settings/video and click the safe area check box and hit apply.
according to the description it is for widescreen monitors and TV's but when i checked the box i noticed i could play h2v on high setting with resolution of 800x600 with my 2ghz single core cpu and radeon 9600 video card.
anyone else tested this?
