One likely explanation is that Reaper has a feature called "Anticipative FX Processing" which appears to pre-calculate some FX processing. It works really well and doesn't affect real time processing at all that I can tell.
Someone wrote that Studio One has added a similar capability, but I can't confirm it, and I have no idea how well it works.

Digital Performer has had that capability for pretty much all of the life of DP9. They call it pre-gen and the newer/current version is called next gen pregen. It works not only on fx but also vi's. I've tried it (there is a way to disable it) and while on simple stuff it can save a lot of cpu usage it's also possible for it to muck with the sound.
I can see it being a problem in PT given it's history with at times wonky delay compensation.
