FSR (FidelityFX Super Resolution). The feature is expected to come to the company's next-generation flagship smartphone, the Galaxy S24. This technology renders a game's graphics at a lower resolution to improve frame rates and then uses AI to upscale the resolution. This way, you get higher frame rates at the cost of a slight downgrade in graphics details.
Well, this goes the other way than ray tracing - it degrades graphical fidelity but improves performance. That should result in better FPS at the same power consumption or lower power consumption at the same FPS in games, and mobile gamers will probably welcome both effects.
