Ex-AMD FSR Leader Reveals “Big Trouble” Meme Explaining FSR 4 Compatibility Issues with RDNA 2/3

Despite AMD’s quiet stance on the availability of FSR 4 for earlier-generation Radeon GPUs, insights from its former head of development suggest there may be more beneath the surface.

Ex-AMD FSR Lead Responds with Humor to Queries About FSR 4 for RDNA 2/3 GPUs

Since the introduction of FSR 4 alongside the launch of the AMD RDNA 4-based Radeon RX 9000 series over a year ago, AMD has chosen not to comment on the potential for FSR 4 support on the RDNA 2 and 3 architectures. In contrast, NVIDIA has consistently made the latest iterations of DLSS accessible for its legacy RTX series, highlighting a significant disparity in AMD’s communication and support for older hardware.

AMD has faced numerous inquiries regarding the INT8 version of FSR 4’s compatibility with RDNA 2 and 3 GPUs, particularly since DLL files indicating such compatibility already exist. Although the community is confident in the technical feasibility of supporting these GPU generations, AMD’s hesitance to launch it officially raises eyebrows. The absence of a clear explanation as to why AMD is holding back on FSR 4 for these models leaves many wondering what the underlying issues might be, a question recently addressed humorously by Colin Riley, the former head of FSR development.

In response to a similar query, Colin Riley shared a GIF depicting a well-known meme conveying, “I prefer not to speak. If I speak, I am in BIG trouble.”This seemingly lighthearted response might hint at his awareness of the reasoning behind the limitations imposed on FSR 4 but reflects a commitment to confidentiality. The persistent silence from AMD contrasts with the growing frustration of owners of RDNA 2 and 3 GPUs who are eagerly seeking clarity.

Meanwhile, many gamers are experimenting with alternative methods to enable FSR 4 functionality on RX 6000 and RX 7000 series cards, reporting promising outcomes. Tools like Optiscaler have provided success in leveraging FSR 4.0, with users noting that the Balanced mode outperforms even the more established FSR 3.1 Quality mode. Users enjoy enhanced visuals, improved clarity, and a significant reduction in ghosting and shimmering effects. Although FSR 4.0 demands more processing power than its predecessor, adjustments have allowed for remarkable performance gains.

Interestingly, there have been reports of FSR 4.1 also functioning on RDNA 3 GPUs via similar workarounds, yielding results comparable to those observed on RDNA 4 systems. Nevertheless, AMD continues to restrict the official release of FSR 4.1 solely to the Radeon RX 9000 series, further deepening the frustration among users of older architectures.
