I thought the nv3x hardware is borked it cannot do HDR ever.
This is a good thing b/c it allows the poor saps that have these cards to play, what Nvidia should do is admit what they did, they should put up a list of what was replaced and say, "This is not a valid comparison for benchmarking purposes, but we wanted to give our users the best experience possible on their cards even if valve didn't"
See then their PR gets to take a stab at valve which they are dying to do I assure you, as well as try to look as though they are trying to help the consumer w/o being accused of cheating.
Some people will still cry cheater cheater, but only those that just like to whine.
