The PS5 Pro is about to get a performance boost that its PC counterpart lacks. While the console will soon receive an upgraded version of Sony's PSSR upscaler, PC gamers with RDNA 2 and 3 GPUs are still waiting for official FSR 4 support, despite mods proving it works.
This disparity stems from a shared architectural foundation between AMD and Sony's hardware. Both the PS5 Pro and RDNA-based GPUs share features, but only the latest RDNA 4 GPUs officially receive FSR 4. The PS5 Pro, on the other hand, is getting an updated PSSR upscaler, with Resident Evil Requiem being the first game to utilize it.
FSR 4 and PSSR are not identical, despite their shared origins in Project Amethyst, a joint venture between AMD and Sony. FSR 4 is designed for GPUs with large L3 caches and ample VRAM, while PSSR operates on an integrated GPU without dedicated AI processing units. RDNA 4 GPUs have specialized matrix instruction units for AI tasks, which the PS5 Pro lacks.
Modders have successfully implemented FSR 4 on RDNA 2 GPUs, but AMD has not provided official support. This leaves PC gamers with older GPUs without the benefits of FSR 4, while the PS5 Pro receives an upgrade. The business rationale is clear: FSR 4 helps sell RX 9060 and 9070 cards, and every advantage counts in a competitive market.
The PS5 itself does not support PSSR, highlighting the exclusivity of the upgrade for the Pro model. While PC gamers with RDNA 2 and 3 GPUs may have to settle for FSR 3.1, it is well-implemented in games like Resident Evil Requiem, especially with its frame generation features.
Looking ahead, it remains uncertain whether AMD will extend official FSR 4 support to older GPU architectures. For now, PS5 Pro gamers can look forward to improved visuals in upcoming titles, while PC gamers are left waiting for an upgrade that may never come.
