AMD Radeon RX 5500 XT 8GB Linux Gaming Performance
Shadow of the Tomb Raider was only recently released by Feral Interactive for Linux and rendered using Vulkan. Surprisingly even with higher quality presets, the RX 5500XT 4GB version was performing the same as the 8GB card. Only when hitting the highest quality preset was a mere 2 FPS advantage to the Gigabyte Radeon RX 5500 XT 8GB.
Strange Brigade runs on Linux under Steam Play and this Vulkan-native game doesn't appear to be using more than 4GB of vRAM at 1080p either on Linux.
