    Hmm ...Microstutter  🤔


    SLI or Crossfire use AFR or "Alternate Frame Rendering"; this means that the first graphics chip displays Frame #1, then the second graphics chip displays Frame #2 and so on.

This is not normal, in other games i have really good frametimes. For example in BF4 that use the same engine my setup works perfect with almost zero microstuttering
