According to a series of tests from Digital Foundry, AMD's FSR "Redstone" technology has issues with frame pacing, which can sometimes result in smoother gameplay when the technology is turned off. AMD has enhanced the FSR 4 technology by adding machine learning-based rendering stages focused on frame generation, ray tracing reconstruction, and lighting acceleration (Radiance Caching). The FSR 4 machine learning frame generation (MLFG) introduced with "Redstone" has yielded great FPS boost on paper, but has cause the system to output spiky frame rate across the game.
This is inconsistency comes from AMD using an artificial frame pacing technology, not based on the actual flip metering present on the GPU. In contrast, NVIDIA's DLSS 4 uses hardware-based flip metering to ensure precise frame pacing of newly generated frames, resulting in smooth, high-refresh-rate gaming with accurate imagery. As with any artificially generated imagery, it is important that the system properly handles new frames and aligns it with the system so it doesn't introduce latency. However, according to Digital Foundry's testing, Industra 2 game sees a frame time ranging from 4-16 ms, creating visual inconsistencies where each frame is persisting for usual amount of time, producing "torn" frame feeling.
