Thanks Y-Phil. I will look at the various preset.

I never had any crashes with GPU rendering, even my old GTX 1080 ti has 11 GB of Vram. In Unity3D I use GPU for lightbaking, and sometimes it filled it up so program had to revert back to CPU.

Off topic: A 6TB 7000 rpm WD has power consumption of 8 Watt. My video card with 420 Watt under full load and CPU with 320 Watt under full load dwarf that. Since I need 5 1/4 cages for my Bluray burner and my HDD hotswap bay, in addition to the hard drive bays, there are virtually no other cases available with that feature other  than one Corsair case I found. I don't want all that stuff external, I have enough wires already. I am a retired RF engineer and I don't want bluetooth or WiFi connections to my work computer out of principle. No matter how good the protocols are today, but there is always outside interference.

I run my HDD for roughly 50,000 hours or until I need more storage. Because electricity is relatively cheap here in Atlanta, I run my computer 24/7. The killer of HHD are the startup current and the heat cycling from being turned off and on. By 20 years I mean I will put a drive on a shelf and sometimes I need old files from 10 or so years ago. After all I have been using Poser since version 3. They had a revolutionary user interface back then.
