Title says it all. I'm getting the same FPS I had with a single gtx 770. I have an fx 8350 on an asus sabretooth 990fx. Control panel clearly states that SLI is enabled. What's going on?Here is a video of my "SLI" performance in BF4:
look for different sli profiles that will work better for bf4 otherwise your performance will be less, and also BF4 isn't really optimised for nvidia cards as of yet.
Same thing happened to my crossfire 7970s. Frames were worse than single 7970. BF4 isn't optimized for AMD either. It's just not built for multi card setups. I decided just to sell the 7970s and buy a single 780 ti
