In Q.U.B.E (steam game), I can make it all the way up to the first few laser puzzles with no issues, but then my FPS will suddenly drop to 10-20.

My PC specs are as follows:

• AMD Phenom II 3.4Ghz Quad
• Sapphire Radeon HD 6870
• 8GB G.Skill DDR3
• 1TB Seagate Barracuda

I will normally get 60+ FPS up until said point.

This is a major issue for me as I am trying to record a let's play of the game, and I cannot progress if my FPS is so horrible!
