I’m using OptiX 5.1.1 with a GTX 760 (driver 441.87, Windows 10) and I frequently get the following error while executing denoising:
Details: Function “_rtCommandListExecute” caught exception: Failed to launch DLDenoiser post-processing stage. DLDenoiser run method failed with error -XXXX
OptiX is used just for denoising, there are no kernels/ray tracing taking place.
The internal error codes mentioned in the message are usually -27 or -4711. Is there any documentation available on those?
Sometimes it seems that it’s probably the system’s watchdog causing the crash. Is there any way to make OptiX put less stress on the GPU while denoising? A potentially relevant function I noticed is setTimeoutCallback() but I saw in an older forum thread that it doesn’t have any effect.
