List of console commands
Below is a list of commands I tested in-game and the values I recommend for them (this will be regularly updated). If you know any more which you consider important for the list, let me know!

FPS
cl_showfps 1
fps_max 101

Crosshair
cl_crosshair_color "500 500 500" (this allows you to use colours for the crosshair which aren't in the options menu — click here[pastebin.com] for various values)
cl_dynamiccrosshair­­­­­­ 0 (prevents crosshair from changing its size while shooting — helps with aiming for some players)
cl_crosshair_translucent 1

Graphics
r_detailtextures 1 (better quality textures)
gl_vsync­­­­­­ 0
violence_hblood 1 (this is on by default - set to­­­­­­ 0 if you don't want blood in your game)
violence_ablood 1 (this is on by default - set to ­­­­­­ 0 if you don't want blood in your game)
cl_minmodels­­­­­­ 0 (this is off by default - set to­­­­­­ 1 to hide all non-classic costumes and classes)

Netgraph
net_graph 3 (shows realtime data about FPS, MS and package loss)
net_graphpos 2 (centres the aforementioned graphic in the bottom middle - 1 is for bottom right and 3 for bottom left)

HUD
hud_fastswitch 1
