Adding mods and high-res textures eats RAM. The Xbox 360 has only 512MB of shared memory. Here is how to preserve "extra quality" without the "extra stutter":

In the modding scene, "Extra Quality" (often abbreviated XQ) is not an official patch. It is a community-driven term referring to a specific package or set of tweaks that usually includes:


| Feature | PC Version | Xbox 360 (JTAG/RGH) | |--------|-----------|----------------------| | Mods | Full script/XML modding | No script mods — only asset swaps | | Vehicles | Dozens + DLC | Base vehicles only (no official DLC) | | Graphics | Higher res, shadows, draw distance | Locked 720p, lower settings | | Performance | 60+ FPS | 30 FPS capped | | Multiplayer | Steam/online | LAN only (System Link) via XLink Kai |


The vanilla vehicle sounds are weak. An Extra Quality pack includes custom engine sounds ripped from Forza Motorsport 4.
