What could make a Linux-Guest run sluggish while Windows ran great?
I'm pretty inexperienced with KVM/Qemu and currently doing more or less trial and error. My current situation is as followed:
I had a virtual machine set up (Linux host; Win 10 guest) with a dedicated GPU for some light gaming. This worked out quite well. A few days ago I decided to see how far gaming under Linux has come, so I set up a new virtual machine with a pretty similar configuration to the Windows machine and installed Cachy-OS as a guest. I was surprised to notice that the performance was way worse than with the Windows guest (I'm not only talking about running games, but also other day-to-day tasks like launching programs, browsing web-pages etc.) I assigned the same resources, so could you help me how to figure out, what makes the system feel so much slower? Honestly I don't really know where I should start looking...
