25-Way NVIDIA/AMD Linux Graphics Comparison For Vulkan-Powered Thrones Of Britannia

First up was the 1080p low quality run, which shows the Vulkan-powered game performing fairly well even on the older hardware. The Radeon HD 7850 (GCN 1.0 / Southern Islands) graphics card when using AMDGPU+RADV had even delivered a 55 FPS average while graphics cards like the GeForce GTX 760 and Radeon HD 7950 / R9 270X were delivering a playable experience in this scenario. The GeForce GTX 960 / R9 285 and above were delivering above 90 FPS averages.

Given the number of graphics cards tested, line graphs weren't used for the frame-time data but rather modified box plots. The average and maximum frame times were comparable between the RADV and NVIDIA Vulkan drivers with no major differences in this very relaxed low quality run.

With medium quality settings at 1080p, many of the older graphics cards were running with around a 60 FPS average while the GeForce GTX 960 and Radeon R9 285 and above would really handle the game well in this scenario. Of the current generation GPUs, the Radeon RX 580 on RADV is competing very well with the GeForce GTX 1060 while the RX Vega GPUs continue coming up short of the GeForce GTX 1070 -- showing more Vega/GFX9 optimizations could be beneficial for the RADV Vulkan driver.

At high quality settings with 1080p, the Radeon R9 290 and GeForce GTX 780 Ti were delivering averages above 60 FPS while the slowest of the graphics cards tested were now pacing around 30 FPS.
