Reducing/Turning Off Particle Effects

team-fortress-2

After spending much time with a laggy game experience, I've come to the conclusion that certain complex particle effects, particularly those of the Hu-Long Heatmaker minigun for Heavy, and multiple explosions going on at once on-screen, cause my game to lag considerably when in effect.

Is there a way to reduce the complexity or otherwise turn off these particle effects to help reduce my lag?

Late answer, but w/e. Taken straight from the wiki:

Multiplayer Decal Limit

The maximum number of decals that can exist at once. Decals are used for visual effects like bullet impacts. Higher numbers will result in more persistent decals, at the expense of performance.

There is a command that represents the Multiplayer Decal Limit, noted by the command mp_decals x with x denoting the amount of decals you want visible in game.

Since decals are responsible for showing sprays, bullet holes, and other particle effects in game, reducing x will in turn lower the amount of particle effects. X can be a number from 0 - 200.00.

If you'd like to have some particle effects (to still show bullet holes, useful for learning recoil patterns and such), an advisable amount is mp_decals 9, which is enough for seeing the Scattergun's spread without sacrificing any performance. In Chris' words (creator of Chris' configs)

maxframes.cfg

mp_decals 1 // `9' is a good value to still see the spread pattern from a
            // scattergun without any real performance loss.
