in the old minecraft version i ran normal settings with 200 fps. With the new snapshot 13w41b i have 60 fps for about 60 seconds then it drops to 40 fps and stays around 40-45 fps. I have 6GB RAM for minecraft. Can you fix it?
Environment
Windows 8 64bit, Java 7 Update 25 (64bit), 12GB RAM
This has also happened to me, and I'm assuming it has to do with the render distance bugs.
