8.2 installed on second machine, with Cuda and zero issues. However, I testing 8.2 projects and opening up CC originated projects are not backwards compatible. If you have to go from 8.2 back to 8.1 Then they'll work.
I remember in the video toaster days when everyone would post their specs on machines that worked for others to digest. Guess we need to do the same on this forum?
My specs:
Workstation:
Win 7 SP1
Dell t7610
Dual Xeon E5-2637, 16 Cores
Dual K2000 Nvidia Quadro driver v. 9.18.13.3182
16GB Ram
Storage:
LSI MR9271-8i SAS Controller (PCI): 2TB 4-disk array, RAID 10 configure for Video.
LSI SAS 2308 Mustang -StorPort (onboard Mobo chipset): .5TB 2-disk array for System
.5TB Media drive on mobo SATA port for media
1TB USB 3.0 Offline Storage Drive (disconnected during edit sessions).
Laptop:
Dell Latitude E7440, 16GB Ram, .5TB SSD single drive. I do cut's only editing on this with media via external USB 3.0 SSD drive. However, no conflicts or issues and runs decent (surprising for usb 3.0 as I used eSATA via pcmcia cards before).
Hope this helps.
