Subpar NNEDI3 (shader version) performance. #216

Closed Shiandow closed 8 years ago

Shiandow commented 8 years ago

With some driver / GPU combinations the NNEDI3 shader version is a lot slower than the OpenCl version. If everything is working correctly the performance should be comparable.

Example: Nvidia GTX 960 with driver v358.50 has trouble running NNEDI3 x16, 720p -> 1440p but not with OpenCl. Nvidia GTX 560 Ti (all drivers?) can run NNEDI3 x16, 720p -> 1440p with both shader and OpenCl versions.

Clearly something is going wrong, but I have no clue what (and unfortunately I can't reproduce the results with the GTX 560 Ti, as it has ceased to be).

Information about other examples or similar problems would be very helpful.

Okay, strangely enough I can't reproduce it anymore now. Closing the issue until someone can reproduce it.
