Extreme Lag

[SupperRobin6394]

Hey lads,

My game keeps freezing for about 1 second every 5 seconds, then it goes back to 40 FPS.
Anyone having any idea?
This goes for both Orbit, Atmosphere, and when warping in orbit.

H to be sure of whats going on  I'd need to see a copy of the KSP.log ( as noted in the how to get help thread) But i suspect that one or more of your mods is incompatible with the version of KSP you are running(, which for all i know could be 1.05 as you have not provided that info).  Those  mods that are incompatible are likely to be writing to the log a lot and if there  are NRE's ( null reference exception, a mod failing to find code etc)  there also,  that would easily explain the issue you are having.
