Dxtory is a small game video capturing tool from Japan, specially designed for DirectX and OpenGL programs. In Dxtory, the video data is directly captured from a surface memory buffer, that's why it is so fast and only needs very little system resource.
If you are a player, especially a guy being fond of PC games, then you must have met the situations of some games can't run normally or they run with all sorts of strange problems.

Of course, the correct version is also critical.
