on my mac there is an option in the driver utility that allows me to further control the sharpness or less of it to a larger extent. It is almost like doubling the NL settings. I can decrease or increase. I can get a woody to stay around 15-30 fps+. I dunno if pcs have options like that so ur on ur own. If your comps is even 4-5+ its time to get a new one if u want NL to run correctly and smoothyl
