No such issue here with RTX 6000 on Linux.

  • Does this happens also in F12 render?
  • Does this happen when starting Rendered viewport with GPU render, or only when switching from CPU to GPU?
  • Does the same happen in 2.79 daily builds?
  1. Blender 2.8

If Classroom is opened up in GPU mode, with the 3d Viewport set to Wireframe, Solid or LookDev, F12 render works.

If Classroom is set to Rendered, F12 causes 'Cuda Error at cuCTXCreate: lauch failed' error message.

  1. Blender 2.79 Build (blender-2.79.0-git.d7cecc2ba3f6-windows64)

If Viewport set to Rendered display halts.
If F12, Cuda error at cuCTxCreate: Launch failed error message appears
