With Gran Turismo 3 on my Pixel 7 phone via the AetherSX2 emulator, the FPS was all over the place--at times it ran at full speed, but most of the time it was in the 20-30fps range and felt very slow. I would not recommend playing this game this way as of now. Perhaps one of the newer forks runs this better--I'll have to mess with that one of these days.
