Jus like the title suggests, it's been years since I've played regular HL let alone ESF, well I decided to play it for fun once again but for some odd reason I keep on lagging really bad & my FPS drops down to 3-8 during melee battles sometimes, I've put the video settings on software so I could choose my resolution(1680 x 1050), should I not have done this? Any help would be hella appreciated. Thanks.
