Severe drop in fps by rotating camera [not fixed]

[Karpen]

Hello,

Since a couple of days I noticed that a lot of times my fps drops heavily without any real reason. Even the simplest crafts yield low fps rates. Then I noticed, that I can provoke this by rotating the camera continously. I made a screenshot of the debug window:

Just when the graph drops, I started rotating the camera by holding the arrow key.

It is the latest steam version, x64, running on a intel i5, nvidia 760 GTX, 16GB Ram, Linux Mint 17.2 Cinnemon.

Installed mods: Mechjeb, Kerbal Alarm Clock, New Horizons (and Kopernicus), ScanSat, TAC Fuel Balancer.

I also just noticed, that it may have started after upgrading the tracking station ... and I saw that if I show unknown objets I get a couple of hundret objects. Now, in normal gameplay they are apparently not shown, but maybe their position is still calculated when the camera looks at them?

 

Any other ideas? Thx.

Just checked. 971 small asteroids around Kerbin .... Do you think that might be the reason? and how do I get rid of them?

So, I fixed it. It turned out that indeed the 971 asteroids were a huge impact on performance. I edited the persistent.sfs file and manually deleted all but 10 or so, and now I am back over 80 fps.

Ok... Afterall it is not fixed. Yes, the drop in Performance comes from the large number of asteroids. But I just saw, while have time warp in the tracking station, that there are continously new asteroids beeing created. I already have 134 asteroids back... at this rate, the performance will drop again. Where is this coming from????
