What am I doing wrong?

Newbie here, got my legion go a few days ago. First 2 games I’ve tried out have been Jedi survivor and a uncharted 2 via the ps3 emulator. Both crash, both are unplayable, is there something I’m missing? I keep my device plugged in, fans are on full speed, set on performance, 60Hz, 1280x800. What am I actually failing to do? Not a single game seems to be working properly and I’m considering just calling it a day and returning this thing
