frequent fps drops from 60fps to ~25fps every 5 secs

[eanity]

before I updated to 1.3, I had no performance problems. However when I updated, I immediately started to have frame drops from 60fps down to ~20fps. This is definitely not because of my computer specs (i7 7700 Processor, 16GB DDR4 at 2400MHz, NVIDIA GeForce GTX 1070 with 8GB GDDR5). I've noticed that as I progress through my career mode, the frame drops have gotten worse. now it is so severe that it has basically made my game unplayable. btw I have quite a few mods installed. (USI Constellation, Kerbal Alarm Clock, KAS, KIS, Kerbal Engineer Redux, Trajectories, For Science, Science Relay). is anyone else having a similar problem, and does anyone know a fix for this?

No log, so speculation it is...

* Open the debug window (MOD+F12) and see if anything is logging errors when this performance drop occurs.

* Install Memgraph, see if the framedrops line up with garbage collection runs. If they do, it's almost certainly the crappy (and ancient) managed runtime that Unity uses, probably exacerbated by poorly coded mods.
That it occurs every 5 seconds and gets worse as your career game progresses (more craft in flight) makes it sound like this is a likely cause.
This problem exists in stock installs, is exacerbated by mods, and lies squarely in the 'too hard' basket as far as Squad is concerned. No fix. Only mitigations are to remove mods that create a lot of garbage and/or use Memgraphs 'heap padding' feature.

If there's no correlation with either, start removing mods a few at a time until you isolate the culprit. I'd start with math heavy mods (e.g. USI, KER, Trajectories) and graphics mods, if you have any installed.
Are you running the same list of mods you were in 1.2.x? Are they all properly 1.3 compatible? Using mods that aren't built for 1.3 will create all manner of problems.

As you have not mentioned which OS you are running, I can't really comment on potential external influences.
That said, if it's Windoze, check out the usual suspects - background services, antivirus and the like, and use whatever system load monitor it ships with to see if something else is chewing up CPU time / disk IO.

I will try all of these possible fixes... thanks for your help!
