Actually, I read a detailed performance review of what I think are still the most recent two versions of Parallels and VMware Fusion and surprisingly Fusion outdid Parallels this time around, significantly in some cases. After reading that I did a trial install and found that VMware did in fact work very well and performance (for a virtual machine) was quite good. So, while I understand that historically Parallels has been the preferred option for running a good number of games, with best results on older titles as a rule, VMware has improved quite a bit now and become a viable option and competitor to Parallels for this purpose without some of the marketing/subscription issues people were unhappy about with Parallels. I've used both and I liked VMware better in the trial I ran of it but until I remove bootcamp in the future I couldn't justify spending for either of them anymore.
Unless something changes significantly by the time I get around to making a purchase, I'll go with VMware. For a variety of reasons I won't get into here I am done with Parallels permanently. I'd do without before doing business with them again but that's just my own preference.
[doublepost=1454864898][/doublepost]I just read here after posting that above that unfortunately, VMware has laid off the entire Workstation and Fusion development teams in the US at least and the future of the products is somewhat up in the air despite assurances from VMware that they supposedly remained committed to them. So that's worth keeping in mind before spending any money on anything from VMware at this point in time. Oh, well. How quickly things change in high tech! Good Lord.
