The intention of this is to reduce effects to try and get a framerate boost without ruining the effect quality too harshly, or removing them entirely.

Does the same as Performance Friendly Flame Weapons, but now applies to all surface impacts, explosions, smokes*, sparks, glass shatters, flames and so on.
Doesn't include the fore-mentioned mod, so install both if you want the benefits of each.
*Not police smoke grenade though.

Majorly it removes some effects entirely such as smoke off fires, or various amounts of dust.
Other parts have been kept for readability, but reduced in number.
Remember to set the 'Effect Quality' slider in Video options to minimum.

Example

50+ particles per pellet impacted Roughly 3~ particles per pellet impacted Not that much of a visual loss.
