Hi Jens, is there any way to disable view-dependent LOD altogether? I notice that when the frame buffer is small, the progressive renderer often stops at LOD 1 and neglects to render LOD 0 at all.

(1) is easy:
Just open the progress viewer and adjust the "minimum quality" slider to skip all but the highest resolution

(2) is hard:
Timing is generally hard, you would have to do multiple frames and then average, but in the case of imagevis3d with it's interruptible renderer, that returns control to the OS multiple times during a frame, it's especially hard to get reliable timings. Still you can get timings by enableling "other" in the debug window. Just make sure to clear the window from time to time as just drawing these messages into the window gets more and more expensive as the window fills.

Cheers
