I hope that’s a good time for a 750 Ti, because I have no idea how to tweak these stuff yet.

It’s not. I got it in 3:00-3:15 with GTX 660
Try 256 x 256 resolution…
You should be able to get under 3 minutes.
Not know much about the subject but I wouldn’t tweak anything anyway. Rendering is a constant 100% performance load for hours and sometimes days, wouldn’t want to overload my hardware.

Thanks for the info. I tried 256 and it was like, 1 second differece thought. But if I change the Light Bounce under Light Paths to a max of 20 and a min of 0 I get a really good time!. I think that’s what I’ll do.
