Poor performance Mac OS and ATI Radeon HD 5870

[du5t3r]

The GPU is ways too old, the drivers are outdated.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.
