Cache Thrash

Cache thrashing is a hardware issue in graphics processors, which is one of the strongest reasons for limiting the number of textures in a given area. It is continually being alleviated by improved graphics card memory sizes, but it is doubtful it will go away entirely for the foreseeable future.

Cache thrashing occurs when the virtual environment uses more textures in visible range than the user?s hardware can hold in graphics memory all at once. When this happens, typically, the API dumps them all out each frame and loads from scratch again. This constant memory swapping results in a slow down and judder effect as some frames are rendered noticeably faster than others, even when the content does not change. This creates a choppy experience and annoys users as it disrupts from both the immersion and the interaction.
