FPS dies shortly after launch.

[GuessingEveryDay]

After launch, the frame rate drops from a normal 15 FPS, with this rocket on the pad, to SPF.

Mods?

While I cannot see the video, I recommend using a mk1 pod, a oscar b tank, and a mammoth engine. Turn on infinite propellant and ignore max temperature. Launch it. Now you have a fast craft with only 3 parts, and the frame rate goes up!

Uh, I don't think that's the issue...

Try to check KSP.log, if something is spamming there, that mod is probably the problem.

Or try to remove mods one by one.

If you have terrain scatter on, maybe turn it off. Check the engine count? It might just be a bug/glitch.

KSP log doesn't show anything.

I have already removed any mods that either I never use, or don't need.

Here's a video of my Electron replica with 51 parts.

Huh, seems to be based on how high you are into the atmosphere. The FPS drops after launch, but seems to start at 1000 meters ASL, worsening until reaching space where it springs to 30 FPS.

[Kerbal Productions]

There is no presence of Scatterer... idk what is goin' on...

[BekfastDerp13]

You do have a large number of engines, maybe try lowering the number?

[GuessingEveryDay]

I was fooling around with mods, when all of the sudden, I accidentally clicked on Trajectories' button (you can see what it looks like in the videos), and all of the sudden, everything turned 60 FPS!  My god, I never had KSP look this smooth. So the problem seems to be with Trajectories' calculations. Which is bad as I need that for my re-entry calculations. Until then, my eyes thank you. Will close this one and raise the issue on the Trajectories' thread. Thank you, everyone.
