I get that perfect translation won't happen effortlessly in a port. But if some effort is made to reproduce old effects on the new architecture, a 2013 GCN GPU really *ought* to be able to do anything an NV2A can without a whole lot of trouble. Some work would have to go into it, of course; maybe perfection is out of budget. But it bothers me that we've seen a progression of ports that haven't gotten any better (actually, CEA's Classic Mode is worse than Halo PC in some respects), which is the opposite of what you'd hope for when GPU shader architectures are getting more complex*. And some of the issues really ought to be a quick fix; for instance, I'm pretty sure the issue in the water in Halo's skybox in Classic Mode is just a LOD bias discrepancy, which you'd *think* could be fixed by setting a single value.

*It certainly seems to have helped Dolphin.
