Running: v0.3 on Win MCE 05
um, occasionally things seem to skip a beat, and I find myself further thatn I expected to have traveled in the amount of time that has passed, and I notice the frames jump up to 500 and then back down. This seems to happen during a collision. When I fly into (not all the way through) an astroid and have a continuous collision with it, then it jumps between 500 and a more reasonable value fast enough that both can be read simultaneously.
For the mousebuttons thing: as far as I can tell, a single quick click is counted as two mouse actions, while a single slow click is counted as a single action. A lot of rapid clicking (firing twice per click, once on the down, and once on the up) can sure fire a lot of projectilies rapidly. I don't know if this helps at all, probably not because you have this info already and then some. oh well.
I have not had a problem running at 1280x1024 yet. Maybe I'm just lucky.
