Terrain collisions with colliders cause alot of lag #4622

Open Gmod4phun opened 7 months ago

Gmod4phun commented 7 months ago

Describe the bug

When a terrain collider collides with a big collider, or with many smaller colliders, it causes severe lag. I can imagine it is because of the terrain density.

To Reproduce

  1. Have a terrain
  2. Place some big colliders into it and see the FPS go down, possibly even stall the game

Expected behavior

Probably better performance, if it is even possible.

They're not optimized, it's temporary until Izabu adds it officially

It's now using the official one, the performance should be better but obviously can still slow it down
