FAQ

Q: Can I play high-quality games in a browser?
A: Yes. Modern browsers with WebGL and WebAssembly support can run graphically impressive games, though performance typically won’t match native installs on powerful hardware. For best results use Chrome or Edge and a desktop with a dedicated GPU.
