    I've purchased Parallels 15 this week to run Win10 on Catalina. Goal was to get rid of Bootcamp and do some light gaming that is not available to MacOS.

    So far I've tried DayZ and Euro Truck Simulator 2 but both games have extremely poor performance (5-10 FPS on lowest settings)

    Setup:
    • 2018 21,5" 4K iMac
    • Intel Core i5-7400 3Ghz
    • 8GB RAM
    • Radeon Pro 555 2GB
    • 256GB SSD

    Parallels set to Gaming and tried all sorts of CPU/RAM settings for the VM. on higher CPU/RAM settings DayZ doesnt even launch to the menu.
    Any suggestions or just bad luck and goodbye money?

    Still no luck, I've been trying to get my Radion Pro 555 to work under Parallels but it doesn't get detected by AMD drivers, display runs on some virtualised graphics driver that isn't even capable to run Paint smoothly
    3D performance sucks balls on Parallels and I'm already regretting I've spent my money on this pile of junk.
    Besides this, not a single support tech has taken the effort to respond or help, great job guys!

    Hi, sorry for the delay in response.
    Could you collect the tech report right after the issue reproduced and post the report's ID here?

    This is just a general state of the VM, no specific error occur other than a lack of overall performance on any 3D application/game that I try

    I'm wondering if the RAM is the issue. I've found Parallels runs much better when your system has more RAM.

    The VM itself runs fine, but the moment something that involves 3D is started the performance goes down the drain. As if I'm dealing with some cheap on-board graphics. (not that the 555 is the greatest GPU in the world, but it performs fine under MacOS or native Windows under bootcamp)

    Well think about it this way, you're trying to game on what is basically a Windows system with 4GB RAM. That's not been practical for nearly a decade. Get more ram (16 (gives each system 8), or if you can do 32 (gives each system 8-16, definitely an improvement)), it'll make a difference. GL!

    Don't forget, this is virtualized hardware. You don't need to install the AMD drivers, Parallels installs it's own drivers that work in-between your AMD hardware and Apple's Metal, providing what Windows needs. Make sure Parallels Tools are installed properly and you'll be good to go.

    Thanks for your input!
    I agree that RAM is an important factor but I'm talking about really, really bad performance on games that are 5+ years old. (basically stuff that my 2014 Macbook Air could run) I mean, Euro Truck Simulator gives 5-10FPS on the lowest settings on a maxed out VM.
