The comparison is not even remotely reasonable.

The alternate timeline would have to be pretty wacky, a lot of his techniques are using modern software development progression. Sure, the N64 was a limited platform, but also they didn’t have efficient and optimized algorithms back then that enabled this type of performance on lesser hardware. That came with decades of experience writing code like this.
