I run a VFIO setup with a single GPU - the linux host is headless, and Windows runs on top with the GPU. Its pretty awesome. Windows runs at native performance - no problem gaming or running other heavy workloads. The linux host acts as a devbox and runs a few other homeserver style services. It's difficult to set up right but it taught me a lot about VMs and hardware. Once you get it setup well enough, its relativel…

I do the vfio thing as well, do you happen to remember the registry editing you had to do to stop stuttering in games? There's a program that can set and unset all the stuff you need but evidently I deleted it. It's the only thing I am missing to build another one or rebuild the one I have. I wish I had believed it was going to work perfectly when I started and wrote everything down.

Server-side solutions don't catch all cheats. They can block actions that are impossible according to the game rules but they cannot prevent clients from disclosing too much information to the player about other players, or automating actions that are technically possible, like using aimbots.

You can definitely handle some of those situations server side (the key word being "some") with enough engineering effort. In regards to player positions: check which player locations are occluded and wouldn't be visible through the geometry, then only send the valid ones for each player. Of course, doing this on high tick servers could prove to be computationally intensive. In regards to aimbots: the clients already…

Which games do you play that require anti-cheat schemes? The last time I checked, many such games explicitly do not support running in VMs and you risk being banned by obfuscating that you are running the game in a guest OS.

Ive played PUBG, COD Warzone, Apex Legends, Quake Champions, maybe a few others. Of course it depends on the game but i think the perception of how many games don't work under VMs is a bit skewed. TBH every thread like this has the “but what about anti-cheat?” post which makes it seem like a big problem but i think only a tiny minority of games don’t work under VMs.

Anti-cheat measures end up blocking mostly the well-meaning players. I know it's sometimes too costly, but game studios should invest more on server-side security measures and mostly distrust the clients.

But distrusting the client doesn’t solve the problem. If a user can see through a wall locally how can ‘distrusting’ anything fix that? What is there to distrust? All inputs are genuine.

The anti-cheat systems end up really just being more menance than use. Tons of money burned on something that cheaters will get around anyways.
