How to fix lag

[Trung]

Hello thank to read, i have some problem about mod and lag

my PC: cpu i3 8100

VGA RX580 4GB

Ram 8GB

When i build a space station my FPS about 60fps but when i build a base my fps drop down to 9-10fps.First i think my pc too weak then i use msi afterburn but my cpu just use 30-50% and GPU 0%( sometime upto 100%) then i think because PRE mod i try to disable it but not thing happend. I dont want to uninstall all mod  someone help me plz

I believe it's because you have a bunch of ships inside your physics bubble.

AFAIK, KSP can only use multiple threads by applying additional ships in your physics bubble to different threads.

You have at least 5 ships in the screenshot, and your CPU only has 4 threads available.  There's some sharing going on there, and that could contribute to the problem.

Does it get any better if you get down to 4 ships in the area?

Check out graphics optimizations. Some options (like ground effects) put additional demand on a CPU already taxed by ship physics.

Too many lights/shadows might be the major issue.

Go to graphic settings and lower/disable Pixel light count and Shadow cascades.

, Physics range extender mod is the Death Star of Kerbal mods.It can be so good and powerful but it can also destroy your frame rates if not used properly .Try playing without it, it shouldnt affect anything...hopefully...make a backup and see if its better.Still so many vessels there as @Geonovast said, 15-20 fps sounds normal for so many things in physics range.

BDarmory without physics range extended sounds like...uhh like not really a good idea.You wouldnt be able to do most ''fun'' things.

Personally in my largest ground bases i just deal with it.I put my brain is slowmo and tell myself 15-20 fps is fine .
