I am experiencing constant very high CPU utilization with the framework, even when there are 1 layer and 1 sprite. This behavior can also be seen with the tests provided by the framework (just by initiating the application and standing in the mainmenu). I am seeing it consistently on two different machines. The way I currently workaround it is by setting the process affinity to one CPU. It consumes 100% of the allocated CPU and leaves the other one for other processes on the machnies.
Is this a known problem? Is there a better workaround or configuration that I might need to do to prevent it?
