AMD's FSR helps 7-year-old Nvidia GPU crush Forza Horizon 6

At a glance:

• AMD FSR 3.1.5 Quality lets a 2019 GTX 1660 Ti hit 70+ fps at 1080p High settings in Forza Horizon 6.
• At 1440p the same card reaches 65 fps on the High preset, but drops below 45 fps on Ultra.
• Upscaling keeps sub‑$300 GPUs viable for modern AAA titles without a $1,000 graphics‑card upgrade.

What the test shows

The author paired a seven‑year‑old Nvidia GeForce GTX 1660 Ti with a Ryzen 5 3600X and 32 GB DDR4 RAM to run the newly released Forza Horizon 6. On paper the hardware looks dated—released in 2019, the card carries 6 GB of VRAM and lacks the Tensor cores required for Nvidia’s DLSS. Yet, with AMD’s FidelityFX Super Resolution (FSR) 3.1.5 enabled, the system delivered a surprisingly smooth experience.

At native 1080p with the built‑in TAA anti‑aliasing, the game managed roughly 70‑75 fps on the High preset, but visual quality suffered from jagged edges and shimmering foliage. Switching to FSR’s Quality preset smoothed those artifacts and nudged the frame‑rate into the low‑70s, providing a more enjoyable experience without sacrificing too much clarity.

How AMD’s fsr works

FSR 3.1.5 is a spatial‑upscaling algorithm that reconstructs higher‑resolution frames from a lower‑resolution source, applying edge‑preserving sharpening and temporal stability. Unlike Nvidia’s DLSS, which relies on dedicated AI hardware, FSR runs on any GPU that can handle the compute workload, making it a universal solution for older cards.

In the Forza tests, the Quality preset applied a modest 1.5× upscaling factor, striking a balance between performance gain and image fidelity. The author notes that while the Ultra preset still struggled with VRAM limits, the High preset combined with FSR delivered the “sweet spot” for both frame‑rate and visual smoothness.

These tables illustrate that FSR consistently adds 4‑6 fps at 1080p and 5‑10 fps at 1440p across the board, enough to push the experience over the 60 fps comfort threshold on the High preset.

Limitations and visual trade‑offs

Even with FSR, the GTX 1660 Ti cannot sustain Ultra settings. At 1080p Ultra, frame‑rates fell to the mid‑40s, and at 1440p Ultra the card struggled below 35 fps, indicating that VRAM (6 GB) becomes a bottleneck when texture memory demands rise.

The author also points out subtle visual compromises: lower foliage density, softer road textures, and occasional ghosting around vehicle bodies. Ray‑traced reflections and advanced lighting effects are absent, as the card’s retro‑fitted ray‑tracing cores lack the performance headroom to run them alongside FSR.

Why upscaling matters for older hardware

Modern AAA titles are increasingly priced at the high end, both in terms of game cost and required hardware. Upscaling technologies like FSR and DLSS extend the useful life of mid‑range GPUs, preventing a costly upgrade cycle every two to three years. The article emphasizes that many gamers cannot afford $1,000 graphics cards, and that upscaling offers a “price‑performance bridge” that keeps titles like Forza Horizon 6 accessible.

Playground Games lists an RTX 3060 as the recommended GPU for 1440p/60 fps, yet the 1660 Ti achieves comparable performance on the High preset when paired with FSR. This demonstrates that the “hardware ceiling” is no longer a hard line but a flexible range shaped by software‑level enhancements.

Conclusion

AMD’s FSR 3.1.5 proves to be a practical solution for gamers holding onto older Nvidia hardware. While it cannot fully replace the visual fidelity of native ray‑tracing or ultra‑high texture settings, it delivers a fluid, enjoyable experience that respects both budget constraints and the spirit of modern racing games. As upscaling algorithms continue to evolve, the lifespan of GPUs like the GTX 1660 Ti will likely stretch even further, keeping a broader audience in the fast lane.
