The generated frames do not have the perfect per-pixel accuracy of natively rendered frames. There can be artifacts, especially around UI elements or fast-moving edges. However, on version 2.10.1, the artifacts are remarkably minimal compared to TV motion smoothing. For single-player and emulated games, it is transformative. Lossless Scaling v2
