Hi guys! I recently bought an late 2013 iMac with the i5 processor and the 780m graphics card. When I play WoW on ultra settings, and fps go below 40 (in cities f.ex.), the game puts a massive delay on mouse and keyboard interactions (also chat). The mouse cursor itself is fine, but clicking, draging and typing is all delayed by about 0.5 seconds. The best way you can see it, is by moving the mouse up and down over the red buttons in the menu. You can see that the buttons are highlighted with a delay. On lower settings or not so graphic intense places, it does not happen. I already tried to play with v-sync, triple buffering, hardeware cursor and the reduce input lag settings. Nothing. I read on the Blizzard Mac forums that this problem is there since OS X 10.7. It does not look like someone solved it so far. Any suggestions?
