1)

A problem of mine happens only for a processor intensive material I created.

The debug build in Visual Studio can run and animate in about one FPS consistently.

The minSizeRel build however is sporadic. Though faster speed wise, it may animate for two seconds, and then stops animating for five seconds, and repeat the process in a non-uniform fashion. During this pause it would be hard to drag the window, as if the Windows message loop is too busy to process mouse/keyboard data. Nonetheless, the default test scene, using the same set up, doesn’t exhibit this problem. Nor is my material using SSE optimizations yet.

Other configurations such as Release have never worked for me.

To solve my problem, I wish to study how Manta handles rendering and keyboard/mouse events without bottlenecking one or the other. For example, are these tasks running on different threads? Are the keyboard/mouse events implemented in Python only?

Though I have Manta working for Xcode, Xcode just refuses on break at many break points I have set up, which is echoed by other Xcode developers.

I wish to try EclipseCDT to see if debugging is better. I built Manta for EclipseCDT in CMake but do not see a project file I can open or import. Any guidance is appreciated.

Thanks
