Because 4 stars wouldn't be enough. There is one thing you should change though, CM doesn't like it if you enable FXAA and MSAA. Better disable FXAA and use MSAA x4 or x8. It crashed a lot on me because of the FXAA enabled.
Besides that, great settings. I also want to point out you can also just take screenshots with all kind of combinations of the F8 key, up to very very large rendered shots. Keys are in the about > important tips section.
