I Give Up
I tried for so long to only game on the Mac. And, it is possible. There are some great games on the Mac. But, so many games are never ported, or are ported badly. Many others that used to work, no longer work, due to the 64 bit transition.
So I bought an Alienware R8 with a 2070 Super. It's not top of the line, but it can play games. I won't be using it for much more than that.
I'm really curious to see what happens with Apples transition to Arm based Apple Silicon. But, for now I'll be doing most of my gaming on a PC again.
