Direct 3d restart, Query not S_OK

[Peppar]

While playing direct 3d has a tendency to be restarted, this causes temporary lagstorms.
I have tried playing on lower graphics (even lowest) but these restarts still occur, my computer should also have no trouble in playing this game on very high settings.

I have the latest drivers for everything in my computer.

Specs:
Processor: Intel i5-2500K Quad Core 3.3Ghz
Graphics card: XFX (AMD) Radeon HD 6950 2GB DDR5
RAM: 8GB

My console.log can be accessed here:

The guide helped me in no way.

I have reinstalled directX, it was the first thing I did.
