I am trying to train a neural net to throw a ball. it being a physics simulation the bottleneck on my training speed of the neural net is the speed at which the game runs. I would like to tie physics updates to frame rate and remove deltaTime from them so that if i can push out 180 frames a second i could effectively train the game at 3 times speed and go back to a locked 60 fps when i am viewing/demonstrating the net. Unity being a game engine normally what im trying to do is a big no no in games so i get why it might be difficult but is it possible to do? or do i have to abandon the physics/fixedupdate stuff all together and handle all movement code myself in update to tie it to my frame rate?
I presume this is 3D physics but it works equally well with 2D physics:
Turn off Physics.AutoSimulation and perform your own Physics.Simulate. You can do this on the default physics scene or can create separate physics scenes tied to a Unity scene and simulate those individually.
