Is this "true" 120HZ, or is it doing a bunch of frame skipping or something else screwy? Also, what are the exact values that games run at? I'm pretty sure "24FPS" shows are judder-free at multiples of 23.976 and "30FPS" at multiples of 29.97, but do games run at exact multiples of 30FPS, or is there some decimal stuff there as well?

Laptops usually don't skip frames. You can verify using this test with a camera: https://testufo.com/frameskipping

Games with uncapped frame rates are not bound to specific rates and run as fast as the system can handle. Games with frame rate caps run up to whatever rate the game is designed for, often 60 FPS. The only way to have perfect smoothness in games is to synchronize with the monitor using VSync or FreeSync/G-SYNC.
