Warframe appears to be another game that gets monstrous gains with FSR + Resizable bar. With these enabled and FSR at the usual 'ultra quality' input resolution of 2954 x 1662 upscaled to 4k, I was seeing about a 250fps average on max settings with the DX12 Enhanced engine running on vkd3d. The game runs butter smooth.Note: This video is aimed at displaying performance gains while retaining image quality, however it is a 4k capture downscaled by my capture card to 1080p video, so video compression/quality will not fully reflect how it looks in native 4k. If you would like to see image quality, here are some 4k screenshots from Witcher 3 which display FSR working to retain image quality while upscaling:https://twitter.com/GloriousEggroll/status/1419528974565269509About 2954 x 1662 game resolution and upscaling:https://gpuopen.com/fidelityfx-superresolution/#qualityAbout Proton FSR patch:https://wccftech.com/amd-fsr-can-be-applied-to-all-vulkan-games-via-protons-fshack/
