Hi dudes!

I have a little problem. I'm doing a level editor where level can be created and played in real time. Now I'm using a QTimer to update my objects (position and logic) and render them (using updateGL from QGLWidget) when somebody wants to play a level.

But using a QTimer is not going well.

"Windows 98 has 55 millisecond accuracy; other systems that we have tested can handle 1 millisecond intervals."

It seems Windows XP has the same problem, just a 55 ms accuracy. BTW, I use VS2005, WinXP and Qt 4.5 on a good PC

The problem is that 55 ms means 18 frames per second, which is not as good as I thought. For gaming I will require at least 30 FPS (60 FPS even better)

Do you have any suggestion or idea?

Do you believe I should use threads or consider them? I dont know too much about theads, What cautions should I take to avoid problems with my UI? (I mean, shared variables or that)

Thanks a lot for your help and time.
