Yes, there aren't many intensive mobile games. But the games that push the hardware have a very large playerbase ie. Genshin impact, Fortnite. So for mobile games this will be a valuable feature if it is implemented well. This won't help with PC games on mobile because frame gen needs games to reach a certain FPS threshold before being useful. It can't make a 15 FPS game playable. All PC gaming on Android benchmarks I have seen focus on older games, not new AAA.
