So last windows 10 update fixed the problems with DX9 games but seems to have broken RTSS (no other overlays present, not even Steam).
There were changes as to how RTSS/AB behaves in the latest version concerning overlays. IF you read a bit, I'm sure you can figure it out. It just takes a little bit of work to get it working now. BUT, have you tried reinstalling AB/RTSS from a clean profile? Starting from scratch always helps to solve issues.
Yes, I read that, there's no other overlays involved and this is a 32bit app (Prime World). I haven't tried doing a fresh install, I guess that could work.
