so alot of the added lag on PNRP coms from all the dead bodies lying around on the floor and also all the blood and explosion decals. I know Assmod has or did come with a clean up all decals but this does them both a favour.

I used this on my RP server back in the day and it was amazing at its job. it would be really help full for the lag and also all theose pesky antlion guards that glitch out and noone can do a thing about. now you can
give it a shot!
