There are some potential discrepancies when the timestep is increased.
Possibly by design, but logging for the sake of completion

Repro steps:

- Open the [Particles] FTP project from Collab.
- In Settings/Time, set the Fixed Timestep to 0.066
- Play the SceneController scene, and navigate to the following:

- (09) Collision / (10) 2D Collisions: - the radius scale (yellow spheres) effect jumps on top
- (11) Collision Improvements - the forces act erratic, and the impacts (especially on the bottom row tests) is quite much stronger
- (17) Trails Module - the external forces test starts scrambled, and eventually fixes itself

Note:
- not regressions, just possible improvement points.
