Game became laggier after disabling the physics calculations of parts

@pedro16797 But after I replaced the blocks with Fuselage, the FPS still decreased,Why??

@pedro16797 That Fuel Tank?

@ChuckNotChunk @plane918273645 it can improve performance in crafts that have many bodies (pistons, rotators, hinges...), if you have a big block of fuselages that have the potential to be combined, it depends on how many there are and how they are configured. It's something I learnt recently.

Disabling shadows, transparency and other changes partially prevents the combination too. They get mesh-combined but not all the part components are shared. It's something we could improve but it's not a straight-forward change and it would only benefit very large crafts.

Does the combination happen with transparent parts? @pedro16797

@pedro16797 Which setting prevents the combinations? If it's only the collision one then I could still keep the drag disabled. I did the changes because you mentioned by disabling those could improve the performance under this post

@Hermes01000100 I changed the both acc

The way this test has been performed is not realistic, since it's a block of parts. The game in these situations combines all the meshes into a single one, but if you disable those options, the combination is prevented.

This is not a bug, but could be improved, a suggestion about an improvement in how tinkered parts are combined would make more sense.

Is this the result of change in collisions or a change in drag? Did you test the two by themselves?
