FPS drop, something called FRenderLast seems to cause it.

[Job Steinbusch]

Hey, I've been having this problem for a while now and never really bothered to fix it but now it's really starting to bug me. I never had this problem or something like it ever before and I have no clue what it is or how to fix it so I hope you people might be able to help me out.
I can play ftb with an fps of 80+, but sometimes it drops to 40-50 stays like that for a while and goes back to 80+. I Pressed Shift+F3 and cycled through the screens and the thing that stands out is something called "FRenderLasr". This is usually at 0.8% but when the fps drops it goes up to 60% and stays that way for a while of drops back to 0.8% and the fps goes back to normal. (also restarting FTB solves it for a while). Sometimes it fixes itself sometimes it doesn't.
It's very random and inconsistent.

I'm assuming the fps drop and the FRenderLast are related, perhaps they aren't.
I'm clueless...Maybe one of you knows what's going on. If you need any additional information I'd be happy to provide it. Any help is greatly appreciated.
