So, us who are affect by the FPS drop, are we just bricks until unknown fix appears?

I wouldn’t say that in general. I see multiple issues being discussed as “fps drop” or “stutters” which look like entirely different bugs to me which I described in this post:

I’m really surprised that most of the people saying the sim is unplayable are such with the highest-end systems (usually RTX 30x0 cards) while many even with low-end systems seem to be quite okay with the performance except for the location specific issues (Manipulators).

I’m running a Ryzen 3600XT, RTX2080, 16GB RAM and the sim runs fine in most cases. FPS issues usually are just for a minute max and then disappear, except for the one caused by high CoherentGTDraw which seems to stay - but I encountered it only once in the last few weeks.
