F1 2018 is another great-running Steam Play title that is benchmark-friendly and its performance came out slightly ahead on the RX Vega 546 while on the other cards the performance was unchanged.
The Hitman OpenGL-powered Linux game saw the same performance between Ubuntu 18.10 and 19.04.
When firing up Rise of the Tomb Raider with its Vulkan renderer on Linux, Ubuntu 19.04 with the updated open-source Radeon drivers was able to deliver slightly better performance.
