I can find the ones for the original SiN, but can't find any for Wages of SiN.

If someone is still interested in these, you just have to use the cl_entities command to get the game itself to tell you which entities it's currently drawing. If you don't want it to flood you, use a command like

"toggle gl_showents; wait; wait; toggle gl_showents"

bind that to some key and you can get it to print them just once. I believe the two waits are needed...

EDIT: corrected the code

Doesn't work. All it does it disable entities and reenable them again.

Whoops. I meant a similar command. Replace cl_entities with gl_showents. Also you have to be in Default OpenGL render mode (don't ask me why) which might not work out the box. If it doesn't, try renaming sin.exe "Quake2.exe", a known way to get some GPUs to use the correct settings.
