I recently came across a situation while using VRAY 1.5. When rendering files sized 1gb+ on machine:
CPU - i7, 322ghz
It slows down like anything. 10 hours to reach 1/4th of prepass 3 of 3.
High Disk I/O, reading and writing 3ds max temp files,
Low CPU Usage(only 1-10%),
This makes the render times go upto 10h where as on render servers with 32gb ram and 16core CPU, it renders in 1h.
Looking at the computer specifications, A guess of rendering time on server vs machine would be a straight double. But this is 10 times high!
What would possibly be the reason for such slow down?
Thanks in advance.
