interior overlay is turned off, this station was sent up in 2 seperate parts and all is fine and lagg free until i either stage or undock with a docking port then this happens sometimes the craft just spawns on the launchpad like this. Either or, it causes my framerate to tank everytime, in the pictures below im pulling about 15-20 fps and its been as low as 10-13 on the moon as i have this same station around the moon. This seems to happen with any part it thinks is an airlock, see attatched photos. In the attatched video the overlay glitch goes away when i undock and switch to starship but the moment i dock back to the station, the overlay glitches as seen and my framerate tanks to the floor.

removing JSI Transparant pods fixed the issue, thank you!

Ok, dupe of #228 then

Please provide your ksp.log file with all bug reports or requests for support. If you can send craft files that reproduce the issue, even better.

If you have JSI Transparent Pods installed, that will cause the overlays of centrifuge parts to render when they shouldn't. But I don't think it would have much effect on performance. Rather I suspect that at some times, the internals of the station are not created but doing certain actions is causing them to spawn, which is considerably rough on performance. Still, if I had the craft file I could hook it up to the profiler and see if there's any low hanging fruit for optimization.

Is the performance issue any different from if you had control of the station and enter IVA view?
