6? That can't be right. I don't know how big a GCU is, so the scale could be up to 1 OOM off, but a full redirection of all simulation capacity should let it in

- Fuzzwah 2y agoThe target precision wasn't specified.
- myrmidon 2y agoFor ball-to-ball collisions, 6 is already a highly conservative estimate-- this is basically a chaotic system (outcome after a few iterations, while deterministic, is extremely sensitive to exact starting conditions). The error scales up exponentially with the number of (ball-to-ball) collisions. So if the initial ball position is off by "half a pixel" (=> always non-zero) this gets amplified extremely quickly. Your intuition about the problem is probably distorted by considering/having experienced (less sensitive) ball/wall collisions.
