At CES 2025, AMD demonstrated the latest version of its FidelityFX Super Resolution tech, FSR 4.0. And, thankfully, HardwareUnboxed has captured some footage from it. So, let’s see what this new version brings to the table.
In the following video, we can see two PC machines with AMD’s hardware, both running Ratchet and Clank. On the PC on the left, AMD was using FSR 3.1 Performance Mode at 4K, whereas on the right, we have FSR 4.0 Performance Mode.
The good news is that AMD FSR 4.0 is finally able to resolve numerous visual artifacts that plagued its previous version. Even in Performance Mode, the image quality is better with fewer artifacts. So, from a visual viewpoint, FSR 4.0 is better than FSR 3.1.
Sadly, AMD has not yet confirmed whether FSR 4.0 will be compatible with older AMD GPUs. The red team has implied that FSR 4.0 will be only for its latest RX 90 series GPUs. However, I’m almost certain that there will be a fallback for older GPUs.
My guess is that by selecting FSR in a game, it will default to FSR 4.0 for the RX 90 series GPUs. For those not owning one, it will fallback to FSR 3.1 (or a less accurate version of FSR 4.0, similar to what XeSS does). Again, this is an assumption and nothing more.
AMD has stated that it will have a separate event for the RDNA4 GPUs, in which it will go into more details about its new GPUs and FSR 4.0. However, there is no ETA for when this will happen. As I’ve said, it appears that AMD has chickened out at the last minute regarding RDNA4. Not only are RDNA4 GPUs present in that event but there is also a working demo of FSR 4.0. So yeah, that’s kind of a bummer.
Anyway, first impressions are positive for FSR 4.0. So, let’s hope that AMD will deliver this time. And, since NVIDIA announced Multi Frame Gen, I wondered whether AMD will follow on this. Will we see it in FSR 5.0? Or will they add it in FSR 4.0?
Take a look at the video and stay tuned for more!

Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2.
