I've found that most people complain about how much the "realistic" guns spam shaders and lag. So here is a fix.
These were tested with css realistic weapon v4 (laggiest weps I could get)
And a vid because pics don't do shit.
It was laggy because of a complex refraction effect, so I took it out >:D
(Putting it in this catagory since it is a vtf edit, and because gmod does not have a sprite section.)
