It's not the granularity, after all it works without the single  
CreateDevice. With the line uncommented the value doesn't even change  
after 2 minutes.
I am not sure what you mean with explicit counter. I think I would still  
need to get some time delta to accumulate. However, time.time() -  
time.time() will always be 0 for obvious reasons.
I agree it would probably be better to use time.clock() and an explicit  
counter to prevent time wrapping issues. Nevertheless time.time()  
shouldn't fail here unless DirectX is really badly tinkering with my  
system.

Thanks for your answer,
