OpenGL Update Speed

Post by Symbols »

Hi,
I was running a few experiments to find out the OpenGL update speed and found that speed to be rather slow. Could you provide me with knowledge on how I could improve the rendering update speed so that the OpenGL updating is a smooth flow on pace with the mouseMoveEvent? I am using a QOpenGLWidget and am following the API guidelines for handling the updates, i.e. only implementing initiateGL(), resizeGL(), and paintGL() after inheriting from the QOpenGLWidget. I call this->update() inside the mouseMoveEvent() method implemented inside the widget. The visual update only renders every half to full second on my Dell laptop. Thank you.

Respectfully,
Symbols
