- The leaked FSR 4 INT8 version unlocks AMD’s latest upscaling feature for RDNA 2/3 GPUs.
- It provides better visuals than FSR 3.1, but the performance takes a slight hit, similar to DLSS 4.
- FSR 4 INT8 provides a visual boost to RDNA 2/3 GPUs, but FSR 4 on RDNA 4 is still superior.
The latest version of AMD’s upscaling FSR 4 is currently available only to users with newer GPUs. The version is greatly improved with better visuals and performance, but the older versions weren’t as good, resulting in bad performance on older cards.
The RX 9000 series boasts an FP8 format that enables hardware acceleration, a feature absent in older cards. However, a new FSR 4 INT8 version has leaked online that allows the upscaling version for RDNA2/3 GPUs.
Why it matters: FSR 3.1 was the last version compatible with RDNA2/3 cards, and while it does provide a slight performance boost, it heavily compromises visuals; the FSR 4 INT8 version helps address this issue.
AMD doesn’t appear to have any official plans to release it, but the builds have leaked online, allowing you to try it for yourself. FSR 4 INT8 (via ComputerBase) does provide a lot better visuals than the older version, but the performance takes a hit.
The FP8 build present on RX 9000 GPUs is still the superior version, but you do see an upgrade in visuals. It does take a performance hit as it doesn’t match the smoothness of FSR 4 on RDNA4 GPUs.
The scenarios differ for various games, but testing shows that FSR4 for RDN4 is significantly more consistent than FSR 4 INT8 on RDN2/3. The trend was observed in Horizon, Cronos, and other games.
The performance even takes a hit compared to FSR 3.1. You do get significantly better visuals, but the FPS goes down slightly. So, this is a trade-off you have to decide if you do decide to use FSR 4.
Nonetheless, if AMD decides to launch FSR 4 INT8 on older GPUs, it will be a worthwhile upgrade. The visuals can match FSR4 on RDNA4 GPUs, and the performance loss isn’t too big compared to FSR 3.1.
