ok heres the deal all my system specs are in my sig ive tried this oced and stock but there just one nagging ass problem....whenever im moving around in the game i get about 4 feet then bam i stick. its not a system hang because i can still look around but my forward movement is halted( i ahve to tap the w key to begin moving again), im getting a solid 85fps with vertical sync enabled so its not a framrate issue, im thinking its my keyboard i have a microsoft wireless desktop 1.1 that has worked great for every game i have except HL2. well this has really got me pissed because at this point the game is totally unplayable.
