Hello,
just a wild guess: In the game Aquanox, some people experienced the
same behavior. Delays in rendering every two seconds, especially on
high end hardware. It turned out, it wasn´t the rendering, but the
simulation which caused the delays.
At the time of investigation into this problem I wasn´t part of the
development team anymore, so i only speak from hearsay:
The apparent cause was a hardware bug in the AMD Athlon series,
related to the use of the high performance timer as simulation clock.
Under high load the timer oscillated, the simulation halted every 2
seconds. The J3DTimer class uses this timer, right?
Cheers,
Ole
