Demo stops working when entering the mine

[Urkle]

Urkle, I think it's about VSync because :
- It's one of the settings that changes,
- I had to disable VBlank in Beryl to fix a little issue with it ( hang when coming back to X from a tty )

Yeah I have that issue too when running the game inside beryl.. Hence I always debug from my Mac instead of from another terminal Never tried turning off vblank.

But in the game sync to vblank is disabled by default.
