There is no singular headline technology that will drastically improve main thread performance in one go. There are dozens of complex systems at play, and even fully removing one of them wouldn't make the game substantially faster. Instead we have many people working across many teams to improve the performance across the board. Often it only takes one piece of code to go wrong to cripple the performance (e.g. a bunch of objects detaching incorrectly and interpenetrating causing physics to struggle), and the PTU tends to expose many of these on each patch, so sometimes the biggest gains are from just identifying and resolving these rather than foundational improvements to the technology (though each team is making big strides in their own areas). It's not a sexy marketing answer, but it's the reality.

I'd recommend enabling "r_profileGraph 1" via the console if you are interested in identifying your performance bottleneck, and that might help direct conversation to particular problem areas (e.g. locations / missions / hardware setups) and we could see if there's more specific answer / information for the specific performance issues hot spots you are seeing.
