I got warnings about several of the MB_clFFTplan_GeForceGTX1080_* files not being found, though. No error messages in the *-benchMB.txt file. I'm about to download the 442.75 driver for another test run. ID: 2041616 ·      Reply Quote

The MB_clFFTplan_GeForceGTX1080_* files are - intentionally - generated by the app on the first run on any given machine, and are disposable: if present, they will be used to optimise future runs; if absent, they'll be re-generated.

I wrote a rather long set of instructions for running the test and sent it to Nvidia, as an addon to to the problem report I sent them about a week ago. ID: 2041880 ·      Reply Quote

NVIDIA is looking into next steps. ID: 2042156 ·      Reply Quote

So .. 445.87 has the fix, for Release 445 Drivers. Thanks, Jacob Klein ID: 2045919 ·      Reply Quote
