odd rendertimes

[nlo]

we are working on a highpoly scene and found a very odd behaviour:
the rendertimes depend on the zoom level of the max framebuffer!
we are rendering to 32bit exr in full hd with a few vray renderelements (velocity, matid, zdepth).
when zoomed in it renders much slower (like half speed) than zoomed out.
is this a known problem? we render now with the framebuffer turned off for best rendertimes.
kind regards.

Have you turned off the 3ds Max Bitmap pager?

Other than that, yes, the display code 3ds Max VFB is a bit on the slow side and does a lot of extra things.
