Render view port subdivisions - Long rendertimes

[Evox_Productions]

I like the "Render view port subdivision" option in vray. But the render times are 5 times longer than rendering the same model using mesh/smooth nodes with 2 subdivisions. Is there a setting Im missing to make this more efficient?

Thanks for any help.

go to vray settings tab, open the Default Displacement & Subd roll-out and change Max subd to 2 (default is 256)

Increasing the "dynamic memory limit" option also helps - the default is 500 MB which is too low in most cases.

Best regards,

Thanks this made a big difference. Someone also suggested switching Default Geometry to "Static". Is that a good idea?
