I also made the clones do minimal GPU + CPU calculations to make the results a little bit more realistic

The project was ran at 240 fps

Scratch Delta calculations are extremely unstable, therefore I added some easing to the Delta and since dips are very likely I made the milestones harder to reach

As for the results:

Unstable 240 fps (<80): 330 clones

Unstable 60 fps (<30): 1073 clones

Unstable 30 fps / Unplayable (<10): 5720-10000 clones (This milestone was cut short because dumbass me clicked fullscreen)

Expectedly during the test, One of my CPU cores were close to being maxxed, but what was interesting was the GPU usage:

Around 4000 clones the GPU usage was around 20%, however at 5000 clones (before clicking fullscreen) it shot up to 50%. Not entirely sure why. The GPU usage is a lot lower than my game Voxelverse, but Voxelverse has a lot of gradients, in fact at least 95% of the blocks in that game have a subtle gradient.

Specs:

Intel Core i7-6700, Averaging 3.6 - 4Ghz during test

12 GB DDR4

Nvidia GeForce GTX 750Ti
