I’ve spent quite some time setting up KVM with GPU passthrough and modifying qemu and my kernel as to circumvent VM detection of anti cheat software. While it worked in principle, overhead from virtualization and reduced core count meant that some resource-heavy games ran extremely poorly (while they would have run just fine without virtualization).
Some won’t even run in vm
