Two modders have stepped in together to deliver a new performance optimization tool. Works exceptionally well for me, my FPS has increased by about 50% in some places.

"New way"? I've been using this since 1.3!
Well not new, but the collab between the two are. I use HD_B, work PC jumped from about 15fps maxed out to about 30ish.
