You might be better off with a simpler look, since you can make that more consistent.
yes... true... definitely gotta be a consideration...
right now i'm trying to get something similar in Blitz... those shots were just examples of the target i'm aiming for... if i can get even a decent looking tone mapping i'll be satisfied...
the screenies above require the end user to have a pixel shader 2 compliant card as a minimum as well... and although there are a large number out there, i'd rather not impose that sort of limitation just yet anyways...
thx for the insights jH...
