cl_radar_scale – this is the map zoom. The slider in the menu only lets you go as low as 0.4, but with commands you can bring it lower.

cl_hud_radar_scale – lets you influence the scale of elements displayed on the radar. Very useful to bring that up a notch if you use an overall smaller radar scale to increase its readability.

cl_radar_always_centered – this determines if the radar centers on the player (1), or not (0). Those who scale down the overall radar preview usually turn that off.

cl_radar_rotate – determines if the radar rotates with your POV (1) or stays in one place (0). It’s totally up to your preference.

cl_radar_icon_scale_min – changes the icon scale on the radar. Usually brought up for the same reason as HUD scale.

cl_radar_square_with_scoreboard – this command determines if the radar turns square on the scoreboard preview (1) or remains circular (0).
