If cl_new_impact_effects is set to '1', Source Engine 's updated, threaded particle system (as opposed to the original engine's system) is used to render bullet impact effects. The results are most noticeable on glass. Certain community particle effect mods may require the use of this command.

If you have been having crashing/invisible model problems after the January 27th update, check to see if you have cl_new_impact_effects enabled. If you do, disable it by setting it to 0 in console, as well as in your autoexec.cfg file if you have one.

This var was introduced in post-2007 Source Engine games, it will in essence switch impact effects to use Valve's new particle system as opposed to their original hard-coded implementation.

These are the new impact particles can be observed in TF2 with the command cl_new_impact_effects 1. I've tried to port them over as accurately as possible, they look 1:1 to me. Note: these can function in-SFM as impact particles, from recording the in-game decals.

BEFORE YOU INSTALL: You MUST use cl_new_impact_effects 1 for this mod’s particles to work! If you don’t have the convar “cl_new_impact_effects” set to “1”, this mod’s particle effects will NOT appear in-game!

Particle impact effects replace the hard coded sprite effects of the original game and have the advantage of offering increased detail and higher resolution assets (the old sprite based effects have the advantage of colouring the impact effects based on the texture hit)

I'm currently working on a content pack for HL2DM that is supposed to replace these effects as I did in TF2, but so far had no luck because of all this being broken in general.
