You missed the point as well, but I've been looking at improving it anyway.

You appear to have missed the point. It is not about the exact count, but about the resolution. You'll see that the Flash player now outpaces Gnash by about 4 to 1.

Framerate can vary depending on external factors like CPU load. Timers use the system time. You've broken it so that a framerate of 13 makes the minimum timer resolution 76ms instead of the expected 10. A function that's supposed to be called every 20ms will only be called approximately every 80ms.

Also this was a testcase I produced in 5 minutes showing just one of the side-effects of the change. I could write any number of others showing different problems. Please fix.

I still get falsecounts even with the delay set to 10ms. Setting "set delay 10" in the gnashrc file overrides any of the FPS based changes, so this is easy to test. I'm more interested in real world testing for the release. End users prefer a lower CPU load.
