Also happens when baking hair dynamics or soft body physics. I get an immediate crash when pressing the "bake" button.

Got under 20s with Titan X in Windows 8.1. Tiles 512x512 seem to give best result.

..please correct me if i'm wrong, but I thought cycles only runs on single precision?

For me it also looks like it's not just a Windows issue but a general problem with Maxwell GPUs. I got a new GTX Titan X primarily for Davinci Resolve which replaced my ancient GTX 670. I got massive performance improvements in Resolve as expected. In Blender (Linux) I did not get a noticeable speedup running my old projects. Unfortunately I can't do any exact measurements on the 670 because I sold it already. But rendering the BMW27 scene (no settings changed) on the Titan X, Blender 2.77, Fedora 23 takes 1:06:22 which is still slower than the 780ti posted above. Maybe this should be split into two tasks, one for the Windows issue and one for the general performance on Maxwell chips?
