Hello, I have this odd problem where when I run the Crysis 2 SDK, I get fine 20-50fps, but when I'm on the standalone free editor, I get like 1-9fps

I'm using a ATI Radeon 5670 HD graphics. I fixed the whole crashing problem from the thread about AMD cards, but I don't fully understand why I'm getting this fps in that editor, other then the Crysis 2 editor.

Thanks for the help!
