While using 3dsmax 2010’s new hardware shading in the viewport, I’ve noticed that my exposure control in viewport is about half of what it turns out to be when I actually render the scene.  I’m using mr Photographic Exposure Control and some photometric Free Lights.  Has anyone else noticed this, or is there a setting to tweak it so I can more accurately preview my exposure in the viewport?

While hardware shading is possible on my machine, the option to enable exposure control in the viewport remains greyed out. This might be very well due to the fact, that currently I do not own a professional FirePro or QuadroFX GPU, but an outdated consumer card (Geforce 6600 GT - don’t laugh).

Does anybody know the minimum requirements for enabling exposure control in the viewport? Realtime AO and shadows work just fine. I’m about to upgrade my hardware and would like to know, what to expect from the different GPUs.

Available on my 8800GTX - actually seems to work too :)

Max 4.2 through 2013.
XP-64 (SP2)
NVidia 9800GTX-512 (Driver 266.58).
Core 2 Quad Q6600 2.4GHz, 8Gb Ram, DX9.0c.

It’s available, but functioning as described in my OP.  I’m using an ATI Radeon HD 3600 Series.

it only exposes direct light (sun and lights), not skylight or any indirect illumination, rendering it only 50% (or less) useful.
