When you first launch PCSX2 1.0, you will face the wizard: Language: Select your preferred interface language.

Most users should keep the default selections. Ensure GSdx is selected for graphics.

Set this to "Native" for performance on low-end PCs, or upscale to 2x Native (720p) or 3x Native (1080p) for HD visuals on modern systems. Texture Filtering: Keep at "Bilinear (PS2)". 3. Boosting Performance (Speedhacks)

If you have a PC from the last 5-10 years, it is highly recommended to download the latest PCSX2 Nightly build rather than 1.0.0, as it features a much simpler interface and better automatic configurations.
