Additionally, even when I had one game running smoothly it was not guaranteed that others were not stuttering.

Unfortunately, after several hours of testing I had to learn that those two categories weren’t enough to guarantee a decent gaming experience. I started benchmarking several setups (found on level1tech, reddit and the arch wiki) using Superpossition Demo to compare perfomance results, and LatencyMon 6.70 in order to measure the input lag. Especially since my main focus are demanding online multiplayer games. In order to optimize the user experience for virtualized gaming, I started to pursue low latency and high performance. This guide describes performance optimizations for gaming on a virtual machine (VM) with GPU passthrough.
