I share my understanding of the game

1. The picture quality on the lowest, to be able to let you see people more easily. You'll look at your far side and notice that the grass doesn't brush out. If someone is ambling, you'll feel like a wriggling caterpillar on the opposite side ......

2. Turn on as high a frame rate as you can (the so-called "frame rate" is how many pictures there are in a second). because the higher the frame rate, the faster your reaction time and, at the same time, the faster the system shoots.
