General / SFML rendering jerkiness

« on: July 14, 2011, 02:19:21 pm »

I have found a solution to the problem, by adding:

Code: [Select]

App.SetFramerateLimit(60);
This removes all stuttering from the display.

I am still interested in learning why this is happening?

General / SFML rendering jerkiness

« on: July 14, 2011, 05:10:00 am »

I have compiled the opengl example here.

Code: [Select]

g++ window-opengl.cpp -lGL -lGLU -lsfml-system -lsfml-window

When the example is run a 3d cube is shown devoid of shading. It might appear to rotate nicely for ~10 frames before freezing up. A few seconds later another ~10 frames are show and it freezes again.

I'm running 64-bit Ubuntu 11.04; the problem appear both with libsfml from the ubuntu repositories, and with libsfml compiled from source.

Any ideas on what is happening?


Edit

Interestingly if I add:

Code: [Select]

std::cout << "Time: " << Clock.GetElapsedTime() << std::endl
to the runloop, most of the jerkiness disappears, though it still stutters occasionally.
