Gran Turismo 4: USACHD Better (Mod Review)
If you’re looking to revisit the "Real Driving Simulator" on modern hardware, the USACHD Better mod is arguably the definitive way to experience GT4 today. It’s not just a resolution bump; it’s a comprehensive restoration that fixes the aging visuals of the 2004 original. The Visual Overhaul
- Enable “MTVU” (Multi-Threaded VU1). GT4 heavily uses VU1 for car physics. This hack alone gives a 20-30% speed boost.
- Set VU Cycle Stealing to 0 (Zero). Do not touch this slider—GT4 breaks if you do.
- Native 4K resolution (vs. 480i on PS2) – Your OLED TV will reveal dashboard details you never knew existed.
- Solid 60 FPS – The original PS2 dropped to 25-30 FPS on tracks like Seattle Circuit or when 6 cars are on screen. PCSX2 with an RTX 3060 or higher holds 60 FPS permanently.
- 2-second loading screens – On a PS2, a race took 15-20 seconds to load. On an NVMe SSD with a CHD file, load times drop to 2-3 seconds.
- Save states – You can save mid-license test. Good luck doing that on a memory card.
For two decades, Gran Turismo 4 has remained the gold standard of console racing simulators. Released exclusively for the PlayStation 2 in 2004 (2005 for the USA), it packed over 700 cars, photorealistic (for its era) tracks, and the punishingly addictive B-spec mode. Yet in the modern era, playing GT4 on original hardware means enduring 480i resolution, muddy textures, and excruciatingly long load times.
