CUDA error: Launch exceeded timeout in cuCtxSynchronize()

Hello! I’m having a problem when I try to render a scene. I get the error in the thread title, and I can’t seem to figure out why. I have a GTX 760 FTW, 4GB, and I’m running Ubuntu Linux. Any ideas? I can’t figure this out.:frowning:

UPDATE: I have a particle system in this scene, 15,000 strands, 35 children/strand. Hiding this from render view allows me to render successfully…I’m on Blender 2.73a.

Hi, this is maybe a driver timeout problem but normally on Windows.
You can try to get the latest driver from Nvidia but it is not easy to install on Linux.

Hi, mib. I’m using the nVIDIA 340.76 driver. The newest one is 346.47, I’ll download it and see if it works.
