Improve Unity Sim Performance

[Roozki]

Ways to go about this:

1. Introduce multithreading in our camera scripts and other scripts as they are all running on the main thread currently.Unity doesn't seem to be utilizing the computer's full power, unsure if this is to do with underused RAM, CPU or GPU
2. Research Unity rendering and other performance settings to better the performance of our sim and ideally also improve the quality.

Overall, Unity doesn't seem to be fully utilizing our computers. We need to locate bottlenecks slowing down the sim.
