If enabled, each frame game will wait untill videocard will finish drawing. Not recommended by performance reasons, but may fix some problems like lagging and some times crashes or freezing. It’s not vsync parameter but rather same as maximal prerendered frames = 0.
FPS limiter feature. When enabled, it set upper limit of frame rate. Useful for keep videocard from overheating or decreasing strange bugs with physics at high frame rates.
Value in frames per seconds at which upper frame rate will be limited.
FPS limiter could be switched on and off by pressing the keys SHIFT and HOME together (they can be mapped to another in config under category [INPUT]). When fps limiter enabled, loading time greatly increases, turn off by keys then.
