I was wondering , why does option - Enable Motherboard Chipset Compatibility is not recomended? I tried, it gave me some frame rates , games now run smoother. Can someone tell me the negative side of this option, cause only thing that I could google is - motherboard chipset compatibility mode' option at the bottom of this box, and RivaTuner will automatically configure a range of settings for maximum compatibility, stability and/or performance on your particular motherboard chipset. This is not recommended as instead you should manually configure all relevant RivaTuner settings yourself, however if you want to try this option to see if it resolves any problems you may have, tick this box.
