AimIsADickRemove all the "//", since those prevent the game from interpreting a line as a command.
Also you should just use mastercomfig; mastercomfig will handle the optimizations for you, and you can also customize settings easier.
I don't recommend creating your own performance mod; your performance mod may use outdated information, bad settings and UI (design), and might be unreliable.

What i wrote in the autoexec:
//cl_cmdrate 66
//cl_interp 0.0152
//cl_interp_ratio 1
//cl_lagcompensation 1
//cl_pred_optimize 2
//cl_smooth 0
//cl_smoothtime 0.01
//cl_updaterate 66
//rate 60000
If this is what you wrote into your autoexec then anything after the the double slashes (//) are not going to be read. Removing them should fix the problem.
Man It's fixed now thank you guys both for helping me.
