The system adjusts resolution based on a desired frame rate rather than shifting constantly between settings.
The system adjusts resolution based on a desired frame rate rather than shifting constantly between settings.
The system tracks your output and reduces quality if it falls short of expectations. It keeps adjusting until you hit the desired speed or reach the lowest supported setting. A range is often used to smooth changes. For instance, aiming for 60 frames per second means resolution shifts only when it drops to around 54 or rises to 66. This stability comes from typical performance levels in a scene, preventing excessive fluctuations. While frame rates may fluctuate within a scene, they usually don’t change enough to notice. Large jumps typically occur during scene changes—like moving from an indoor space to an outdoor environment, where rendering demands shift and resolution drops accordingly. From a personal view, these transitions feel smoother because you’re moving between distinct settings.
It’s unclear whether this addresses the question directly, but it’s interesting. The performance varies based on your monitor’s specs—some systems don’t support FSR at all, while others can use it for higher resolutions like 4K. For a 1080p display, FSR isn’t typically recommended, whereas a 1440p setup allows it to upscale effectively. Thanks for asking!
The concept behind FSR (and similar technologies like DLSS, XeSS, TSR) is to run a game at a reduced resolution and then apply an algorithm to enhance its appearance as if it were higher quality. Initially, FSR 1 was straightforward—it simply applied a filter to the lower internal resolution. But FSR 2 and newer versions leverage data from several frames to improve results. These contemporary upscalers function like advanced temporal anti-aliasing (TAA), designed for lower resolutions. They typically operate at fixed internal settings. DLSS offers four tiers: Quality, Balanced, Performance, and Ultra Performance, with Quality matching roughly 67% of the original resolution, Balanced at 58%, Performance at 50%, and Ultra Performance at 33%. XeSS, after version 1.3, uses a more compact set of values, while FSR and TSR align with DLSS’s pseudo-standard. Using FSR 2/3 at 1080p is discouraged because the output often appears blurry and riddled with artifacts, especially since even Quality mode operates at 720p resolution. This limits effectiveness due to insufficient data for processing. All upscalers struggle here compared to DLSS and XeSS, which employ more sophisticated AI-driven methods. FSR 4 provides an edge, making it a better choice for RX 9000 series cards at 1080p. At 4K, Quality mode reaches 1440p, and Performance remains at 1080p, giving FSR 2/3 a noticeable advantage. Dynamic Resolution and FSR can coexist in some titles, allowing players to adjust internal resolution percentages for better visuals.
