Grain free Render settings as follows-from my viewing of SM's tutorials on Superfly rendering- setting the bucket size to 256 does NOT make faster renders. I set to 32 or 64. Screen Shot 2019-02-02 at 4.48.21 PM.png

That's certainly true for CPU rendering but it's the opposite for GPU rendering. Maxwell does pretty good with 256, Pascal loves a bucket size of 512 or more depending on the scene. If I'm rendering with my 970 I tend to use 384 and I usually stick with 512 with my 1070 or if I'm using both cards to render a scene.

I used to always go with a bucket size of 256 on my 1070 but after trying 512 my renders started finishing 4-10 minutes faster for larger scenes.
