Total SLI n00b here. So I gained about 10 FPS with SLI as opposed to single GPU in rFactor 2 - similar story in rFactor 1. Really? Is this all you get for having 2x the GPU power in this game? I've read that with SLI you can expect only about 80-90% of the performance of a single GPU increase, but in rFactor 2 it's only about 7% for me. Any advice? This is ****ing me off a bit to be honest. PS: I have Force Alternate Frame Rendering enabled in NVCP. I've tried both 1 and 2, same performance as one another.
