Recording with fraps cap fps at 15 - 20, without its around 30-40 fps. Don't know why it lags a lot using fraps. but my ave. is 25 - 35 w/ no fraps.
Notice: If you experience some lag or delayed sound. check your graphics driver if you already updated to 296.10 or higher to improve graphics settings & bugs and most of it set to performance instead of quality for best fps. If not go to Nvidia Site: http://www.nvidia.com/object/notebook... If you use Vista then change into vista 32 bit. & etc.... I heard there's a new driver for GT 600 series & its 301.42. but try it maybe it will works for you!
