If you have dual GPUs or an iGPU plus a GPU, you can use passthrough and play your games with near native performance in an isolated Windows virtual machine under Linux.
To answer the first part, when you shutdown the VM, your stuff will persist, so no you will not have to reinstalled all your stuff on the VM every time.
For the second part of your question, (to my knowledge, please correct me if I’m wrong) no Mobo has a built in GPU, some CPUs have integrated graphics and I believe you can get that to work on the VM as well. Otherwise you could use integrated on the Linux host OS and use your GPU for the VM exclusively, but your overall performance may take a hit when not using the VM

Ok, but what happens when you shut down the virtual machine and start it back up? Do you have to reinstall the game?
Also do I have to have 2 expansion slot GPUs or will the MB built in GPU that is not being used, work for this purpose?
