Ok, so here's a new one. Decided to play for a bit now that S6 is live and getting a small but very annoying issue. No warning my screen with go black, game is running still behind the black. After a few seconds the game comes back and is fine. Sometimes the gaps between the going black is several minutes, some times it doesn't happen for half an hour, sometimes it takes a few minutes from the last blackness. As you might imagine, these can be a major problem in the middle of combat.
Anyone have any ideas? Using a dual NVIDIA GeForce GTX 560 Ti setup. The drivers are updated to 304.79, which is the current version avaliable by Nvidia.
