OpenCL Error: Unknown error waiting for idle on GeForce GTX 1080 Ti (Device
I have a GTX 1080 but was having the same problem. Crashing within 20mins of use or less when I clicked on a nurbs curve/animation controller. The outliner getting spammed with that message.
I changed a few settings, and it seems to have mitigated the crashing. These are the settings I changed in the preferences window:
Display -> Viewport 2.0
Rendering engine: DirectX 11 (I have a feeling this one isn't necessary, but I've kept it on)
Animation -> Evaluation
Uncheck "GPU Override" (this may be the critical one)
GPU Cache -> Hardware Information
Uncheck "Set All to Automatic"
GPU Cache -> OpenGL-Based Selection Options
OpenGL Selection Mode:
- Uncheck "Automatic"
- Select "Use Vertex Arrays"
