Forza Horizon 6 FSR4 workaround 100+

Johnny Tsag posted on X on May 22 that he had found a workaround for Forza Horizon 6 players seeing shimmering and aliasing with the game’s built-in upscaling options. His post said the issue showed up with FSR 3.1.5 and XeSS in his build, and that forcing FSR4 plus Frame Generation removed the visible artifacts he had been seeing. He also said the setup pushed the game above 100 frames per second on Extreme settings with ray tracing enabled. The post circulated as players compared image quality and performance in the game’s first week on PC. ### What did the player say was wrong with the default image quality? Johnny Tsag said on May 22 that Forza Horizon 6’s native upscaling choices were producing “shimmering” and aliasing in motion in his setup. His post specifically referenced FSR 3.1.5 and XeSS, which he said both showed visible instability before the workaround was applied. A YouTube guide published May 21 described the same pattern in similar terms, saying the game’s built-in FSR 3.1.5 and XeSS options produced shimmering, pixel instability and blur before an external replacement was installed. That video is not the original source of the claim, but it matches the symptoms described in the X thread. ### What exactly was the workaround? (youtube.com) OptiScaler’s GitHub page says the tool can bridge and replace upscaling and frame-generation paths across GPUs, including support for DLSS, XeSS and FSR inputs. In practice, that lets players swap the game’s default upscaler path for another one when a title’s shipped implementation is limited or missing features. Johnny Tsag said he used that kind of forced replacement to run FSR4 with Frame Generation instead of the game’s stock options. (youtube.com) His post said the result in his build was “zero artifacts” while keeping performance above 100 FPS on an Extreme-plus-ray-tracing configuration. ### Why does FSR4 matter here? AMD’s current documentation says FSR Upscaling — formerly called FidelityFX Super Resolution 4 — is the company’s ML-based upscaler and is designed to reconstruct higher-quality frames from lower-resolution renders. (github.com) AMD says the newer upscaler is meant to improve sharpness and image reconstruction compared with earlier FSR generations. (youtube.com) VideoCardz, citing AMD’s FidelityFX SDK 2.0 materials, reported that FSR 4 was designed to improve temporal stability, preserve detail and reduce ghosting relative to FSR 3.1. A March 2026 XeSS SDK update from Intel, meanwhile, said XeSS 3 combines super resolution and frame generation features across supported hardware. ### Was Forza Horizon 6 missing some AMD features at launch? (amd.com) Overclock3D reported last week that Forza Horizon 6 launched on PC without native FSR Frame Generation, saying DLSS was the only built-in frame-generation option exposed to players at launch. A Steam discussion from players also described the game as shipping with FSR 3.1.5 upscaling but not AMD’s own frame-generation path. (videocardz.com) That gap helps explain why third-party workarounds appeared quickly. If a game ships with one vendor’s frame generation but not another’s, players often turn to wrapper tools to test whether different combinations improve either image stability or frame rate on their hardware. ### How much should players read into the “100+ FPS” claim? (overclock3d.net) The “100+ FPS” figure came from a single user report on May 22, and it was tied to one unnamed PC build rather than a controlled benchmark set. The post is useful as an early field report, but it is still anecdotal. AMD, Intel and OptiScaler all publish documentation on how their upscaling and frame-generation systems work, but none of those sources validate Johnny Tsag’s exact result in Forza Horizon 6. (overclock3d.net) Players looking to reproduce it would need the same game version, similar hardware and the same replacement path. ### What comes next for players watching this issue? (youtube.com) Forza Horizon 6 players are likely to keep testing replacement upscalers and framework updates while Playground Games’ PC version matures. OptiScaler’s repository remains the main public reference point for the workaround path, and AMD and Intel continue updating FSR and XeSS materials that developers and modders use to track compatibility.
