Mechjeb Linux Stutter

[jelmew]

Hi All,

Does anyone have a solution. Slapping mechjeb on anything gives lag/fps drop every second. This problem seems to get worse the more ships there are out there using mechjeb. Removing or launching anything without mechjeb makes the game behave just fine. I suspect that mechjeb tries to calculate the delta_v for every ship at every physics tick, making the game unplayable. Now I do rely on mechjeb, I'm better at building than at flying. Does anyone have any idea how to fix it?

The game is ran at 64 bits ubuntu.

Greetings,

Jelmer

EDIT: THe same occurs in 32 bits windows.

I have had this issue as well. I think it is because MechJeb is doing some CPU heavy math every second, and it gets worse the larger and more complex the ships are. My best fixes are:

1. Disable landing prediction --> This is really calculation intensive

2. If the vessel is really large or complex and MechJeb has no idea what the Delta-V is anyway, just disable those windows

3. Point the camera at the sky (Yeah I know there are no views, but the FPS goes way up in general, and also allows more CPU time for MechJeb

Hope these help!

Hi

Unfortunately, none of these do anything. I already tried those.

1. Doesn't matter.

2. Doesn't matter.

3. Doesn't matter either.

The vessel size does not even seem to matter. Small probes with mechjeb, which were launched early in the save and did not lag at that time, do lag now. Landing predictions are off, autowarp is off, camera poisition does not seem to matter. The fact that vessels which do not lag do lag now, seems strange to me. Any other ideas?

I'm having the same problem on 32-bit KSP in Windows 7. It's extremely annoying to use mechjeb when it makes the game lag so horribly and freeze every few seconds, not sure how it's so popular... It needs some serious optimization. As soon as I attach the mechjeb part in the VAB, the lag begins.

1.) I don't think it's doing landing predictions in the VAB...

2.) Craft size has no relevance to the stuttering at all. Even the mechjeb part by itself causes stuttering.

3.) Again, not relevant inside the VAB.
