Always low FPS (between 15 and 25), making the game unplayable, especially as infantry. Infantry showcase seems the worst of all, but every showcase and also multiplayer has low FPS.
Al settings on the lowest, except for shadows (those are on standard, low gives even more FPS drop). Resolution: 1920 * 1200.
Cpu usage max 25%, GFX usage card 1 50%, card 2 95%
