I recently build a sli system, when I set up my system, I decided to test out FSX for the fist time, I got decent performance about 19 fps on KSEA runway, I decided to test out fsx with Sli off, when I loaded it up I checked on the Ksea runway I got 26-29 fps, I limited it to 30 in the settings. My question is why is the fps so different between single vs sli? Is it a software issue or a hardware issue? -ThanksMy SpecsQ6600 3.04ghzMsi 750I SLi 2 9600 GT4 gb ramx64 vista with all the updatesLatest Drivers
