OS: Windows 10
GPU: AMD R7 265 (Driver version 17.9.1)
Broken: 2.79 Hash:5bd8ac
Description of Error
As of the latest update 2.79, under USER PREFERENCE>SYSTEM>CYCLES COMPUTE DEVICE will not recognize my AMD R7 200 series GPU using architecture Pitcaim. However, As of version 2.78c, the GPU was recognized right away under these same settings. Not sure if this is a bug or if the compatibility for this GPU is discontinued which would make me sad and somewhat more broke :(
Ultimately, can not use the GPU rendering on the new update (2.79). I uninstalled the 2.79 update and rolled back to 2.78c to confirm the difference. With no other external updating of drivers or software, the GPU still works with 2.78c. After testing again and again on 2.78c, I uninstalled and installed 2.79 and still confirmed no GPU rendering for 2.79. AMD drivers as of now are up to date.
Other than that, love the denoising, and I think the CPU rendering on my end has improved greatly! And I got an 8 year old AMD FX processor.
