I downloaded win 8.1 preview, bootcamped it and ran the benchmark. This is my test score, the results are 'comfortable' running on lowest settings with a 1280x720 resolution. I tried using the settings with a 1920x1080 resolution and it dropped to just above 2k. I'll be sticking with 1280 for the time being. I wasn't in the beta nor do I have early access. Will update with game play experience in the next few days. I tried to run it in wine before going the bootcamp route but it was just too problematic. While I did finally get it to run, the graphics were shot and all I got was a matrix like screen.
