David,
My frame rate trends typically are more in line with yours. However,
with the latest cvs code, default startup aiport, no hud, no panel,
I'm seeing:
dynamic objects (latest code): ~23-24fps
no dynamic objects (latest code): ~75fps
So I am seeing a huge difference with dynamic objects on vs. off.
This is with a 1Ghz class cpu, 256Mb RAM, and GeForce2MX running
Linux.
With dynamics objects on I'm also seeing a lot of choppiness
(i.e. inconsistant frame rates.)
Regards,
Curt.
