Quality describes how much of the diagonal thin triangles are cut off. Quality=-1 is 3-stamp mode which has these rectangle artifacts
Here are the results I get: Without Hardware acceleration: 3-stamp mode:~400 tps quality=0: ~700 tps (why is this higher) quality=20: ~300 tps @KryptoAlt's STTF Bitmap v1.1: ~200 tps Hardware acceleration enabled: 3-stamp mode: ~5000 tps quality=0: ~3000 tps quality=20: ~900 tps @KryptoAlt's STTF Bitmap v1.1: ~12000 tps Hardware acceleration + TurboWarp: 3-stamp mode: ~26000 tps quality=0: ~24000 tps quality=20: ~6000 tps @KryptoAlt's STTF Bitmap v1.1: ~41000 tps
