Hey all thanks for taking the time to read this,

I've been using V-ray for around 6 months now, but am battling with producing a crisp clean render which is frustrating! The final render looks almost identical to how it looked 2 hours before.

I produced the render attached in 3 hours 50 minsand yet it is still grainy! I've uploaded my rendering settings below. The final file size is 8.59MB.
I removed everything from the model that wasn't necessary and purged the model before rendering.

The PC I'm using it a Lenovo ideapad 700 core i7, with 16GB RAM.

Any tips to smooth out the render or speed up the rendering time would be much appreciated. Thanks!
