 - New KSP QoL/performance patch : [**LowerMinPhysicsDTPerFrame**](https://github.com/KSPModdingLibs/KSPCommunityFixes/issues/175) : Allow a min value of 0.02 instead of 0.03 for the "Max Physics Delta-Time Per Frame" main menu setting. This allows for higher and smoother framerate at the expense of the game lagging behind real time.  This was already possible by manually editing the `settings.cfg` file, but changes would revert when going into the settings screen.
