Well, seems effects lower fps such as additive or xor.
The number of blocks which show the light effects the fps.
When all these are removed the fps stays high!
Don't know what to do about this unless I can find a less demanding way of rendering the light...
Think I'll tidy it up and just release it and see if anyone else can come up with a good way to render...
