Turning down a bit quality of effects

Since I’ve started playing GMod on my laptop (Dell inspiron) I started lagging while shooting somewhere, I am sure it lags cause of smoke effects. So theres my question, with option affects on quality of those effects ? I need to turn it down a bit! Thanks !

Anyone ?

I dont really understand, but go to Options, Video?

Whats your specs?

The smoke can’t just be removed.
I think.
