Here’s a bold statement: AMD’s future in the GPU market could hinge on a single decision—whether to bring FSR 4 to older Radeon GPUs. And this is the part most people miss: while FSR 4 has been a game-changer for Radeon, its current limitation to RDNA 4 graphics cards feels like a missed opportunity. When AMD unveiled FSR 4 last year, it finally closed the gap with Nvidia’s DLSS in terms of image quality, but at a cost—it left owners of older GPUs in the dust. However, a leaked INT8 build of FSR 4 hinted at a different possibility: FSR 4 could work on RDNA 3 and RDNA 2 GPUs, albeit in an experimental form. But here’s where it gets controversial: AMD has remained tight-lipped about official INT8 support, stating they have “no updates to share at this time.”
Let’s break this down. On RDNA 4 cards, FSR 4 leverages hardware-accelerated FP8 math for AI upscaling, a feature older Radeon GPUs lack. The leaked INT8 version, however, bypasses this limitation, and gamers have already tested it successfully on RDNA 3 and RDNA 2 hardware. While it’s less polished than the FP8 version, it’s a functional proof of concept. Here’s the kicker: AMD could follow Nvidia’s lead, which allowed older RTX cards to use newer DLSS versions via the DLSS Override feature. Sure, performance might not be optimal, but it gives users a choice—something AMD seems hesitant to do.
Why does this matter? AMD’s RDNA 3.5 GPUs and laptops are already on the market, and leaving them without FSR 4 support feels like a strategic misstep. Even if INT8 FSR 4 is slower than FSR 3.1 on these GPUs, the image quality improvement is significant. By enabling FSR 4 on older hardware, AMD could earn goodwill, boost the appeal of their laptops and handhelds, and silence critics. So, why hasn’t AMD pulled the trigger? Is it technical limitations, or are they saving it for future hardware? What do you think? Should AMD prioritize backward compatibility, or is their focus on new hardware justified? Let’s debate this in the comments—your take could spark the next big discussion. (Join the conversation here: https://forum.overclock3d.net/threads/amd-comments-on-fsr-4-int8-support-plans.105090/)
