Exact same settings, GPU is noisier than CPU?

[joey145]

Sketchup + VRay Next Update 1.

Only 1 Dome Light in the scene.

Default 'High' settings.

Exposure Auto.

In order for GPU to clean up the noise, I have to raise Render Parameters > Max Subdivs to a very high value like 40. This will slow down the render to the same speed as just using CPU alone so it's kinda pointless.

Am I missing something here?

Are you using progressive or bucket? If progressive, how much time do you have it set to? If it is progressive, it’s going to depend on your hardware and if cpu is better than GPU, then it’s going to render more during that time frame because it’s quicker at computing.
