Hey again,
In a 2d scroller game im making i seem to get FPS drops at random
points, i am using the Clock class to keep it at a constant 60 fps and
it never seems to go above 9%-15% cpu usage so im not sure what could be
causing it.
Seems to run well for 90% of the time with spikes that drop the fps to
10-40 at some points in the level, other times it runs fine at exactly
the same points and its not doing anything extra doing these spikes, im
bliting about 100-200 sprites per frame.
Some quick profiler output, doesnt really tell me much tho:

Any help or suggestions for better profileing/tracking down the lag
would be good :)
