I remember when WoW transitioned to their 64-bit client the existing game profiles no longer applied to the new client. Will the new client operate properly with multi-gpu setups? Will we have to wait for a new NVidia profile, they seem to be reluctant to support major changed in existing mmo clients aside from WoW, when SWTOR changed their shadow engine it pretty much broke multi-gpu and NVidia never supplied an updated profile. Asking because I am running 970 sli @ 4k resolution and the game runs acceptably but only barely so, if I lose 20-30 percent of my fps the game will not run acceptably any more.
