Hi,

I'm using a dial to move a robot but the dial doesn't move at the same speed as my mouse so I have some troubles to see a correct movement of the robot (all in a openGL widget).

It's true that the movement of the robot is preceded of a huge amount of calculations and matrix operations. However, in C++ it shouldn't be a problem.

Is it possible to have a bottleneck on the signal/slot communication?

Any other ideas and solutions? Thanks
