My thoughts on TG2 render times are well known ( just do a search here)....so, I won't add much to what has already been said here.
However when we look at this issue from the artists viewpoint, an interesting question comes to mind....
What do you as the artist consider to be an acceptable render time to produce a print quality 3200X2400 size image?
I fully understand that image complexity, objects, amount of water and reflections can dramatically affect times....so, the answer would not be precise....but, would you be happy with 70hrs, 100hrs, or 500 hours for a typical image of this size? What would be acceptable to you? As a hobby "renderist", what would you be willing to put up with in the way of render times?
If todays state of the art "consumer" computer still requires 150hours to produce a 3200X2400 render...is that acceptable to you? Will it affect your decision to purchase this software?
Secondly, has Planetside in their development of TG2, looked at this issue from this viewpoint?....in other words, have they considered render time implications on potential product sales...or, was the focus on producing a software package that gives the desired end result, without factoring in how long it would take to render that result?
A lot of questions....and I know there won't be a standard answer to any of them....but it would be interesting to hear what folks think about some of this....
