I was messing around with Icarus' tug-of-war prefab and I am getting very bad lag. This is the whole map I had mad so far. (Wanted to practice with displacements) It's a bridge, 8 pieces of track, the prefab, and 8 displacements. When I load up, my fps is around 200. After about ten seconds it's under 100. After a few more it stops at ~20 fps. It does the same on full bright, and the whole map is in a small 2d skybox cube. No leaks.
