Hi, noticed that Attila performance was incredibly laggy after the most recent windows update on December 14th or so. Previously game ran great on maximum quality settings. I have an AMD R9 270X GPU. Drivers are all updated. Just really unusual this is happening out of the blue. I have tried everything. I suspect that for whatever reason the game is trying to use the integrated graphics chip on my processor, but i cannot figure out how to switch that with the new AMD Radeon interface. Please help.
