Ok so not been playing for a bit just wondered what had changed config wish for use autoexec users who like to whore fps n get the reg just right

So what you know?

This my currently my autoexec.cfg

cl_cmdrate "66"
cl_interp "0.033"
cl_interp_ratio "1"
cl_updaterate "66"
rate "25000"
fps_max "100"
cl_interp 0.02
bind 8 "incrementvar cl_interp .01 .1 .005"
bind 9 "incrementvar cl_interp .01 .1 -.005"
net_graph 1

Then I can change something called "lerp" ingame with 9 and 8 (increase/decrease). The lerp should be as low as possible. But the numbers following lerp should be white. White = Very good, Orange = Good, Red = Bad

Whats Ierp lol?
I put settings to get max fps (seems like 999 is max for some reason). Should I change my settings? Or is "Ierp" not that important?

Is that 'Ierp' good? What does it actually mean?
