I kinda suspect that half of the reason they've done all the rewriting is specifically to deal with the idtech4 choppiness. Just a guess, though.
i hope they've rewritten the timing stuff as well, not only the renderer. because from what i could find out through config changes that's where the choppiness happens. it really doesn't depend on the renderer.
take quake wars as an example: i turned off everything and it still had this hickup every second. see the pic below. i recorded it, created an image sequence and aligned a red line at a fixed point of an object in every image of the sequence. see the gap (4th to 5th line on the right)? that's what happens on my sys (and several others i've tested) every second. the gap is small, maybe that's why most don't notice it. but i do. and others do as well. i had a talk on irc where people didn't notice it before, but when i told them where/how to look, they noticed it as well.
someone said that it will be fixed for brink (fingers crossed), but then i ask myself why it wasn't fixed for quake wars or any other id tech 4 game. only a beta will tell. although i'm not sure if i will be giefed one, because if it still hitches, i'm going to be very annoying ... here's the screenie i was talking about:
