Hello, I'm using Parallels 11 with windows 7 (x64) on my macbook pro 17" (mid 2009) El capitan. I'm having some trouble in the game Final Fantasy XI, where the 3D graphics sometimes appears color-negative. The menus, icons etc are ok, the problem only seems to affect 3D. I tried several things I found on internet, like let the "resolution screen window" open when playing the game. Or shutdown explorer.exe in the task manager , etc... Nothing solve the problem. Any idea what I can do ?
