I'm having a few problems with Forge at the moment but I'll start with the most pressing. 
  
It doesn't start off right away and I tried duplicating whatever may of caused it but after a while, it seems the tree's leaves and glass panes will flicker. I would say its z-fighting but it doesn't look quite like it, nore is there any textures to fight, that I can think of. 
  
The only mods i'm using are NEI and the core mod required for it. 
  
My other problem is that the entire game seems fairly laggy. I allocated up to 4gb of ram but it did very little to help. 
  
Lastly, I can't seem to get Optifine to work. It shows it loaded but doesn't actually do anything (My other issues are without this installed, as I assumed Optifine may be the issue.)
