Ray trace is till grainy after 37 passes

[EvanDesign]

I've done this a few times now and changed the settings and just let it run, but 37 passes? Thought it would look better then this, am I missing something?

I think the problem is there are no bikes in that garage and that makes it a sad place! For help with something like this, you need to post the plan, or at the very least, your Chief version, computer spec's and all the specifications of the lighting and camera and materials you are using.
