Also, as noted in the original pre-caching thread.. the best possible loading performance will be acquired by using both pre-caching *and* texture compression. The downside is that the textures don't look quite as nice (whether you notice depends on the particular texture, and how it's used). It'll also use less memory on both the system and the videocard if you do that, but it'll take even longer to load when you run the game.

Thanks for the explanation Incarnate. In any case its faster, seems so anyway.
