I've been trying to get my head around all the aspects surrounding RT and GPU rendering. I'm a solo freelance arch viz person with moderate work load and home office. I'm specing a new system and I'm striving to set it up to potentially/hopefully take advantage of RT. Thinking good system but not bleeding edge. $3-$4K. Here's a link to my parts list so far. https://pcpartpicker.com/list/NjvKkT
I've read the vray GPU rendering guide and followed thru some of the discussions on this forum. Especially the "GPU BOX" thread started by glory bound. I think I need a GPU for my head because I'm having difficulty processing all this. Hopefully my questions aren't foolish or cause any confusion.
Am I correct in my understanding:
1) It's possible to use RT in CPU mode and not use GPU?
2) If I want to work with RT GPU I should have two video cards? One for the monitors/shaded viewports and one to process the RT? If yes I see the Titan 12G card is the best possible for this, but would a GTX 1070 8 G be reasonable?
3) I understand there is a memory limit and so, if using an 8G card for RT, then the scene must not exceed 8G. I don't often exceed that but have recently worked on a scene or two with lots of 3D vegetation (using forest pack) that exceeded that. So in that case one would revert to CPU rendering?
4) Scenes rendered in RT will not appear the same as scenes rendered in regular CPU (bucket mode BF/LC)? This seems like a pretty big caveat. I like the idea of using RT for all the test renders to get materials and lighting all tweaked but I'm concerned if I do that and then render with CPU it would not look the same?
5) If I use RT in CPU mode for test rendering would that then look the same as rendered in regular CPU (bucket mode BF/LC)?
Thanks for any help in getting a better understanding of this.
