It's depressing to find that the same problems persist in Parallels 13. Last year, after many years of running an old version of Parallels (with XP!), I was forced to upgrade in order to run the latest version of a windows application (i.e. the one app that forces me to use windows!). Everything used to run well on my Mac Pro (and I was able to use the hardware available). After "upgrading" to Parallels 12 and Windows 10, performance fell off a cliff. It's tough to quantify, but judging on startup times, it could be as bad as a 50 fold drop. The application is virtually unusable. The problem is compounded by Parallels now restricting memory and number of cores. I read the support pages and tweaked all the obvious settings. No improvement. The only change I have not made is upgrading my hardware with an SSD (I'm not inclined to do that as a speculative change). The bottom line is that I have completely lost confidence in Parallels and can't see wasting money on upgrading to version 13 as it sounds like these performance problems persist. Why has this become so hard? For years it was a good solution. I just want it to work and it doesn't seem like it does with later versions. I may give Fusion a shot, but I'm becoming inclined towards buying a dedicated Windows box, or seeing if I can run Windows under boot camp on my previous Mac Pro. I'm interested to hear what others are doing, since it doesn't seem like Parallels is offering concrete solutions. Obviously some people are getting acceptable performance; so why is it that some of us aren't?
