Then there was the horrendous 6+month waits for driver releases to support CF meaning 90% of the time the second GPU was disabled. I ended up selling my second GPU and everything seemed to run so much better even if it was lower FPS.
If SLI is worse, then I have no idea why anyone would even consider multiple GPUs from either brand. Thanks for clearing things up for me that SLI is even worse than that garbage CF setup so I'll never be tempted to try it.
They have fixed all those Issues, also Battlefield 4 Memory leak happened on Mantle, if you were using Mantle then you'd have a memory leak regardless of how many GPUs you were using, using 2 just would greatly accelerate how fast it'd take to saturate the memory.
As it stands now, Crossfire Frame Pacing is leagues ahead of Nvidia and I'd dare to say the experience is the same as single GPU, Performance is not only leagues but light years away from Nvidia with DX9 and DX11 so this is a non Issue anymore, also the new Crimson Driver have improved in the Que Size when rendering Frames, so input lag have decreased a ton as well.
I only use AMD for multi GPUs solution now for a reason.
