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!

Note: The FPS is horrible even if I'm not recording.

  • The game is running off of the unreal engine. Last I heard, it doesn't run as great on ATI cards. Feb 4, 2012 at 6:27
  • @JeffMercado As I said, I normally get 60+ FPS when playing. Also, AMD replaced ATI's graphics cards several years ago.

  • ATI/AMD, you know what I mean. ;) Feb 4, 2012 at 6:32
  • Is the FPS still so bad when you're not recording? Feb 4, 2012 at 7:01
  • @BlueRaja-DannyPflughoeft Yes, it doesn't matter if I'm recording or not.

Well I finally figured out the cause of this.

As I am recording with Fraps, and Fraps uses the HDD relentlessly, my disk was rapidly becoming fragmented as I recorded.

Whenever I encounter this issue again, running a quick defrag fixes it right up!
