iirc the Rift S and Quest update tracking at 60Hz, but they do one update for the headset itself and the next for the two controllers and so on, so it's 30Hz of tracking individually. The graph posted earlier on tracking SDs should give you an idea of accuracy - it'll be fine.

For vrfps with inside out the main issue you may have is your hand holding a gun's foregrip may get occluded. You can learn to get around this but it's still annoying and can throw off your aim. Beyond that, Rift S tracking is perfectly adequate to be competitive in, say, Pavlov.
