Frame Rate and Grip

This lesson runs in the lab with lesson 1's SlipMeter on the Player and lesson 2's edits undone.

Frame length

Lesson 1.2 showed the problem in one table. A grip applied once per frame gripped about five times harder on a 144 Hz screen than on a 30 Hz one. Here is why the fix works, the same fix for drag, and the small error the fix still leaves.

A frame is not a fixed length of time. A 30 Hz frame lasts nearly five times as long as a 144 Hz one. Any rule that does something "once a frame" does it more often per second on a faster screen.
