Former AMD FSR Lead Drops “Big Trouble” Meme When Pressed On Why FSR 4 Still Won’t Run On RDNA 2/3

AMD has not explained why FSR 4 is officially limited to RDNA 4 GPUs, even though reports say an INT8 build can run on RDNA 2 and RDNA 3 cards.

When asked about the restriction, former FSR lead Colin Riley replied with a meme that appeared to signal he could not comment.

Meanwhile, some users are still enabling FSR 4 and FSR 4.1 on older Radeon GPUs through third-party tools like Optiscaler.

The issue matters to owners of Radeon RX 6000 and RX 7000 cards who want access to AMD’s latest upscaling tech without buying newer hardware.
