This allows you to view KSF replays played on Counter-Strike: Source in a local server. Many replays can be played at once and remain synchronized with each other, allowing you to spectate individually.

Compatible with SVR, which can be used to create historical record videos or record comparison videos where you need to have more simultaneous players. The replay viewer will also produce smoother and more accurate playback without teleport lag, compared to traditional interpolated server side demo playback.
