Either due to NDAs or unwillingness to commit to the extra work, no developer thus far has confirmed they will implement VR multi-GPU thus far.For VR SLI, UE4 has implemented support, so games made using Unreal should at a minimum suffer litle-to-no performance penalty, and possibly benefit slightly (not to a dramatic degree) from low-hanging-fruit optimisations if the devs even want to try. It may not be worth trying for just basic optimisations due to potential backlash from users getting less speedup than expected. AFAIAA, Unity has not implemented VR SLI yet, at least in public versions.Luquid VR Crossfire has not yet been implemented in Unity or Unreal in any public versions. Cryengine support was announced last year (though only for LiquidVR in general, no guarantee as to which features of it would be implemented), but has yet to materialise.
