I think this is an issue with the flashes and/or smokes. After playing for a while, my FPS will drop from 300+ to less than 50 at times. It's incredibly annoying. I've noticed that there were several updates after this special FPS dropping update. Why would this not be fixed yet? Or why isn't the update rolled back. Please fix ASAP.
Also, someone mentioned something about deleting the flash folder from the resources folder - this does not work.
