I migrated to Vray Next a few weeks ago and I notice that previous scenes that have fog now render extremely slowly. New scenes as well.  
I send an example of a region of 990 by 200 that is taking more than an hour to render when before it would take less than ten minutes.  
My render settings are quite low, Image sampler 8 subdivs.

Best you send the scene to [support@chaosgroup.com](mailto:support@chaosgroup.com) so we can take a look. Mention this thread in the e-mail as well.
