Hi Kelvin! Ok, here some more heuristic findings with the DX implementation. Now, I tested @home with XP, GeForce2Ti, driver 6.13, DX8.1 as it comes with the DXSDK (no debug-dlls installed). @work, it has been W2K, GeForce2MX, 6.13, DX8.1
Obviously, the GC is not the reason, it stays completely calm. The phenomen does not show up all the time here, but seems to be correlated with the current FOV. So I have to fly around a bit in order to see it. Surprisingly, the TaskManager does not show any significant CPU usage (~8%) under 'normal' conditions, although the simulations runs with ~25fps and a real lot of geometry. When the delays show up, the CPU usage also climbs to >50%. Later more, - J > >Works well (i.e. as before) with the OGL/Win32 package. Does not run > >fluently with the DX stuff.
