Animation slower in OSX than in Windows

[Jose Luis Da]

Hi all, 

I wrote a code that displays an animation of a plaid, this plaid is drawn with OpenGL.

I have developed it under a Windows, but I also want to execute it under OSX. The code runs correctly, but the animation, i.e. strips of the plaid moving, is significantly slower.

Has anyone of you experienced something similar? What may be the cause of it?

I have attached the code and the files it uses for you to see.

Thank you,

jl

I saw that in an old pyweek entry of mine.

The problem is using time.clock as a clock source.

In windows it provides the High Performarce Counter, and it goes like a wall clock with high resolution.

In linux like, including mac,, time clock is more akin to process time, end is much slower than wall time.

At the moment using time.time solved my problem.

Notice that time.time is more coarse than time.clock, which can be a problem.

Hi Claudio, thank you for your response.

I have changed my time.clock() calls to time.time() and it solves the problem, so thank you.

I also want to make this python script an executable, and for this I have used PyInstaller, which does the job. However, the animation goes back to be slower. Do you know what may be the cause of it?

Thats weird.

I would carefully do a clean pystaller build, rechecking it points to the intended sources, and if that fails ask in the pyinstaller list (probably with a reduced script demoing the problem)
