"FutureMark: I personally think HDR is a great thing, and urge every
developer out there to go for it! If it's done right, it can open up many
new doors of visual treats for gamers. I have read many discussions about
HDR on the net, and there seems to be very mixed opinions of what HDR really
is/does. Most users think HDR is simply a new "better" bloom effect than
what was possible on SM1.X/2.0 hardware. That's not entirely wrong, but
certainly not the whole truth."
