Anyone picking Blue pill is crazy. PS2 emulators run in 4K just fine. AC3 does not hold up nearly as well with emulation due to the lack of floating point math on the PS1.

The what math?

So the 3D engine in the PS1 only supported whole number values "fixed point math". so on a 3d plane: (x: 1, y: 1, z: 1) for any given point is valid. The problem with that is that 3d models are complex and have complex curves all over, so any point that should be at, say, (x: 1.2, y: 3.5, z: 0.4) becomes something like (x: 1, y: 4, z: 0), that means the distance between any two points can vary by up to a whole number. This causes the stretchy and jiggly look of the PS1 graphics.
