Hideyuki,

Thank you for taking the time to address our concerns. For now I have requested and received a refund for the OS X client, but I look forward to seeing the progress you make and will certainly re-purchase if the performance improves to at least be close to Windows. A 20% hit would be one thing, but I see a 60-70% reduction in FPS at matching settings. I am intrigued in your idea to leverage both Metal and the DX11 client. They both sound promising and I look forward to seeing the results.
