Ok, perhaps I'm a moron, that's entirely possible, but I thought the 980Ti was CUDA.

Blender shows GPU as default (which is grayed). I go into system settings, it doesn't show Cuda.

However I check the "FlipFluids addon" and this clearly shows the GPU is seen.

I'm on Mac 10.12.6, 12-core, running Blender 2.79b.

Any suggestions?

I've searched Google, NVidia website, reinstalled drivers, deleted Blender/reinstalled.

And when I switch to OpenCL it crashes.

I'm stumped. thanks, alldaron

  • $\begingroup$ "I'm on Mac": well, there's your problem..you probably need nvidia cuda driver for macos. $\endgroup$ – Jaroslav Jerryno Novotny May 21 '18 at 17:58
  • $\begingroup$ Yes, I have that installed, CUDA Driver Version: 396.64 --- GPU Driver Version: 378.05.05.25f01 --- NVIDIA Web Driver 378.05.05.25.f01 $\endgroup$ – Alldaron May 21 '18 at 17:59
  • $\begingroup$ That 378.05.05.25f01 driver supports only gpus up to GTX 680. You probably need 9.0.197 version that is the last for Sierra 10.12.x Newer versions require OSX 10.13.x. $\endgroup$ – Jaroslav Jerryno Novotny May 21 '18 at 18:15
  • $\begingroup$ Awesome, thank you!! ugh all this is so annoyingly confusing. $\endgroup$ – Alldaron May 21 '18 at 18:25
  • $\begingroup$ Installed, now mac shows: CUDA Driver Version: 387.178 --- GPU Driver Version: 10.18.5 (378.05.05.25f01) $\endgroup$ – Alldaron May 21 '18 at 18:30
