Aethersx2 Windows 11 Guide

| Game Type | Native PCSX2 (Win11) | AetherSX2 via WSA/BlueStacks | |-----------|----------------------|-------------------------------| | 2D (e.g., Disgaea) | Full speed | Playable, minor stutters | | 3D (e.g., God of War) | 60 FPS (mid-range PC) | 20–40 FPS, audio crackling | | Heavy (e.g., Shadow of the Colossus) | 50–60 FPS with tweaks | Unplayable |
