Historically, if you tried to pass a GeForce card through to a virtual machine using standard drivers, you would hit a wall. The consumer drivers included code that would detect if they were running inside a VM. If they detected a hypervisor (like KVM, QEMU, or VMware ESXi), the driver would intentionally cripple performance, limiting the number of supported vGPUs or disabling critical features necessary for a smooth virtualization experience.
This limitation frustrated the Linux and Vgk Driver
However, in the context of the broader tech community—specifically on forums like Reddit, GitHub, and Level1Techs—the "VGK driver" is most famous for a different reason: Historically, if you tried to pass a GeForce
