How to fix aliasing and jagged edges in Star Wars Outlaws?

It's ironic; the cooler handles the heat, but the visuals look like a mosaic. In 4K scaling, distant starships had jagged edges that were eyesores. I first tried enabling native anti-aliasing, but the frame rate was halved from 65 to 32 FPS, a disastrous trade-off for smoothness. I entered the GamePP Image Sampling Calibrator, locked the sampling rate at 88%, and bumped sharpening to 68. CPU temperature stayed at 62-68℃ per AIDA64, GPU temperature remained at 65-72℃ per GamePP, and clock speed hit 4.8GHz stable per CPU-Z.
