Choppy gameplay, game freezes every 7~8 seconds.

[nedlee]

Problems:

Modded gameplay is choppy, game often freezes for a very short time in every 7~8 seconds in VAB, SPH, or while flying.

Also, performance is very low; sometimes get 10 FPS while flying in kerbin atmosphere with 100 parts ship. Sometimes I get bit better FPS(~40) upon restarting the game but not sure why. Vanila game does not have similar issues. I've tried to run games with few selected mods and compare performances, but failed to find out what mod is causing problem.

Finally, I've played previous versions (0.23.5 and 0.24) with some mods like KSP Interstella before, and sometimes had very low framerate (~10) as well. I'd like to know if I've got too many mods for this laptop or I have some sort of mod conflicts.

The first log is from a short session of loading up a ship orbiting Kerbin.

The second one is where I load up SPH, launch a jet, and fly around a little bit.

Thank you.

Thanks for following the Support sticky guidelines!

There's nothing obvious in your first log that would explain the frame rate issues. Based on the mods you have installed, the most likely problem is thrashing the page file – using more memory than is physically available for KSP. There are a couple of ways you could try to work around that:

• Close all other programs while playing KSP, or restart your laptop before you play.
  
• Make Active Texture Management more aggressive by increasing the scale setting in KSP\GameData\ActiveTextureManagement\config.cfg. For testing purposes, try making that 8, and then dropping back to 4 to improve texture quality.

Did some testing and there seems to be no difference with both options. Oh well. Thanks anyway!

It's also possible there's a specific mod causing the slowdowns. You could try removing mods one at a time, putting all the other mods back in.

I don't have these mods from your list, though I'm on a Mac and using OpenGL:

Contract Window 2.2

Dmagic Orbital Science 0.8.6.1

Editor Extensinos 1.4

Fine Print 0.59

Kerbal Attachment System 0.4.9

Kerbal Joint Reinforcement 2.4.4

Mechjeb2 2.4.0.0

Mk 2 Lightning Cockpit 1.3

Near Future Pack 0.3.0

NEAR 1.3a (I have FAR)

Precise Node 1.1.1

ScienceAlert 1.8

Universal Storage 0.9.0.242

Those would be good mods to try removing first.

Removing some of the mods made lags happen less frequently, but did not eliminate them. After some extensive testing it seems that I have this problem in vanila game as well, but just much less noticeable; I found very subtle lags in every 30 seconds or something while looking at a stock craft sitting on runway in a newly installed game. Installing mods lowered framerate quite a bit and made the periodic lag issue quite annoying.

Thanks again, and maybe I should format my HDD and reinstall everything this weekend.
