AMD recently released FSR 4 Redstone Frame Generation, which, in our testing , provided a decent uptick in perceived smoothness and image quality. However, one of the biggest disappointments for Team Red gamers was that Redstone is officially exclusive to AMD's RDNA 4 GPUs, limiting it to GPUs in the RX 9000-series cards. One enterprising Reddit user, however, has seemingly managed to get FSR 4 Redstone Frame Generation running on an AMD Radeon RDNA 3 GPUs—and no older than RDNA 3—using OptiScaler and the same FP8 workaround as was previously demonstrated to work with FSR 4 Super Resolution .

The full methodology is explained in a Reddit post shared to r/radeon , but it should be noted that it only works on Linux and requires the use of Valve's Proton compatibility layer to work. The redditor tested the frame generation implementation with an AMD Radeon RX 7800 XT and notes that it introduces about twice as much latency as the Frame Generation implementation in FSR 3.1.6—adding around 0.14 ms latency per generated frame versus 0.07 ms on the older version—although they do not comment on performance or image quality differences between the two. This does reveal, however, that AMD is intentionally using Redstone as a method to help artificially segment its product stack, which is not sitting well with a number of commenters in the same Reddit thread that the workaround was made public. The full workaround follows.
