Theoretically that one should give a huuuuuuuge boost in performance. So far it looks good in beta builds, but hard to judge without those other hurdles Morness mentioned still in place."4.0 dropped it to 30fps, and internally we've got this decoupled now.. so the game updates run at 30, the fps runs at whatever you want, but we're still working on some UI issues. Hotkey lag has been solved, but drag selection has not (but we're super close now). Text rendering is also super expensive, but we've got an idea how to drastically improve this. "
Definitely, it's looking very promising though. It sounded like the decouple was the biggest challenge and that alone makes it feel like Christmas. I'm confident they'll work out the text rendering too, really doing a good job over there.
