I am getting horrible performance with Mac Pro / Radeon 5870 under Mac OS, but on the same machine under Windows everything works fine. Running vBulletin>v3.8.5 hashes with an input mask.

The device order is flipped between Mac OS and Windows, but they each appear to be using the video card properly.

By manually trying different tuning parameters I was able to get the Mac version time estimate down to 30 days, which is still way off the Windows time of 6-7 days.

I ran a Luxmark benchmark on both OS and the Windows one was about 10% faster than the Mac, not many multiple times faster.

At this point, I'm stuck and could use some help. Thanks

edit: forgot to mention Windows 7, and have tried Mac OS 10.10, 10.11, and 10.12

The GPU is ways too old, the drivers are outdated. I'm sure you had to use --force to get it working. There's a reason why we put that flag there. Solution: Trash the GPU, buy a new one.

I don't need to run --force on it except when testing different parameters. It runs perfectly fine on Windows.

But OK.
