High CPU usage #47

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What is the expected output? What do you see instead?

The program has 50 % CPU usage on my dual core processor, meaning it's hogging 
one of the cores entirely. I would expect a simple program like this to use 
maximum of 10-20 %.

What version of the product are you using? On what operating system?

v0.9 on Windows 7.

Please provide any additional information below.

I have a suspicion this is caused by active vsync polling in the display 
drivers. I have encountered the same problem with some SDL apps.

This problem is an Allegro 4 implementation thing. You can find more

Sadly, but I have almost the same behavior on Linux.
