I've been waiting on someone to comment or post a review for gaming with Parallels 10. I'll go first since I know there are others that are wondering like me. I went ahead and upgraded from Parallels Desktop 9. I am running Windows 8.1 as my VM, and I only use this VM to play games via Steam. The upgrade went smoothly. Before I started the VM I changed the settings to be "Optimized for Gaming" and I was able to increase the video ram to 2GB. I have a 4GB vid card in my system. I never have any problems playing Windows games through Parallels except when I play Skyrim. All my Windows games play great already through PD 9, but Skyrim is the benchmark. With PD 9 Skyrim plays well, but gets really jerky in the video in places that are busy. I do play the game on Ultra video settings, and I realize that I could lower the settings to smooth everything out. The first thing I noticed was when I started Skyrim the usual video buffering required before my character starts moving was greatly improved. Running around in Skyrim proved to be a very smooth experience. There are still some issues when around a lot of water, but I am satisfied with the performance improvements that PD 10 has over PD 9. Sadly, DirectX 11 is still not supported, but that really isn't a show stopper for me. Most of the newer games are getting Mac ports as well. I would imagine before too long that only legacy games will be left that support only Windows.
