You can force FSR 4 Redstone to work on RDNA 3 GPUs with new workaround for Linux systems — solution requires Proton compatibility to work properly

A Reddit user has devised a workaround to enable FSR 4 Redstone on older RDNA 3 GPUs, specifically for Linux systems, requiring the use of Valve's Proton compatibility layer for proper functionality. This workaround allows users with Radeon RX 7000-series GPUs to access machine-learning-powered features like neural radiance caching and ray regeneration. The FSR 4 technology was initially limited to AMD's latest RX 9000-series GPUs, but modders have made it compatible with older RDNA 2 and RDNA 3 cards, albeit with higher performance costs. Some gamers criticize AMD for restricting FSR 4 Redstone to newer hardware, speculating it could be a strategy to boost sales, while others hope for eventual official support on older models.
