Explosion Performance Increase

Has anyone ever noticed that when in-game when either the mortors explode or a tanks main gun fires, that frame rate for the most part takes a nose dive. I can run Black mesa around 35-40 FPS, but when these instances occure my fps goes down 2-3. Which brings me to this thread…is there anyone who can rework the partical effects for those explosions so their less taxing on those of us with less powerfull rigs?
