Smoke/Gun lag

So any gun pack that I have downloaded. Besides the default ones, have awful lag when i shoot a full clip for any machine gun. I don’t know if this is the gun or smoke but i saw this error in the command prompt. Attemped to precache unknown particle system “generic_smoke” . Anyone know how to fix this?

I have this problem too.
I think it’s because of that “Refracting” particle that they have for the muzzleflash.
It’s annoying.

Did you happen to find a way to fix it?

No, I haven’t.
The only thing I can think of is to replace the muzzleflash particle file with a different one that’s less laggy.
Unfortunately, the Particle file is packed into the Gmod Addon files, and I’m not sure if there’s an unpacker to extract it with.

Do you have CSS because I don’t, and that could be the problem.

this is all dependant on your graphics card. nothing to do with missing games.
