yeah its enabled, in fact the fps are always good, the graphic config doesnt seems to be the problem except with the HDR, if its turned on it gives me terribles levels of stuttering, without it the stuttering is much less noticable but its still there, you never know when it will apear
btw maybe it has something to do with the windows i installed? its a win7 64bits although i only have 2gb ram.... other games are fine, warband vanilla is fine actually, but i dont know, i just tried a million things and dont know what to think anymore
