I'm quite new with v-ray so I want to know which are the best settings for drafts render? My last draft render took 30 minutes, 640x480px. I'm using a HDRI map in a V-ray Dome light. I have to mention that i have a lot of glass, but the model is quite simple. I tried to get the settings as low as possible. I attached my v-ray settings.
My specs:
i7 - 2.7GHz, 2 cores, 4 threads.
Video - 2GB.
RAM - 8GB DDR.
