18-Way Radeon GPU Benchmarks On Ubuntu 17.10 With Linux 4.14 + Mesa 17.4-dev
ET: Legacy as the open-source game project built around the popular Wolfenstein: Enemy Territory game becomes rather lax at 1080p on the newer Radeon GPUs, but included this test anyhow for those interested. It does show how Radeon GPUs have evolved since the launch nearly one decade ago with the Radeon HD 4000 series.
OpenArena does show more scaling and a 4.3x improvement in performance from the Radeon HD 4870 to Radeon RX Vega 64.
Though there still are some relatively high peak frame times with the newer hardware on this Linux 4.14 + Mesa 17.4 driver stack.
