I have enable SLI Multi-GPU ,but what I don't understand is waht this does in the advance settings ,It has SLI Multi-GPU Rendering and it has SLI Single-GPU rendering,what do each setting actual do.

Multi-GPU uses multiple GPUs (Graphics Processing Unit) to render the graphics. Single-GPU will only use one GPU. Multi-GPU will be the fastest.

I personally never use single-GPU mode. If I have a compatibility issue with some application then I just disable SLI altogether. With the 8x.xx drivers this works best because you won't have to reboot when enabling/disabling SLI.

So if your using Coolbits, I take it SFR / AFR etc force Multi-GPU ?

I keep the Enable SLI multi-GPU set that way all the time but what I am talking about is in the advance settings,it also has SLI antialiasing in the drop down box,I get about the same score with either setiing,and where do you set SFR and AFR modes ,I don't see them in the control pannel.

Yes. And Multi-GPU rendering is the same as "Auto".

You'll need to install coolbits to get AFR and SFR modes to show up. These settings are useful for games that do not have predefined application profiles.
