Well my make is not well optimized, and i just realised this after i've added a ton of stuff.. Like the title describes sound delay this is what my consoles spams me (its different from which weapon i'm using of course); BlockingGetDataPointer: Async I/O Force weapons\machete_swing.wav ( 0.64 msec / 0.64 msec total ) 346.874711 BlockingGetDataPointer: Async I/O Force weapons\machete_swing.wav ( 0.49 msec / 0.49 msec total ) 346.874711 BlockingGetDataPointer: Async I/O Force weapons\machete_swing.wav ( 0.66 msec / 0.64 msec total ) (I can only hear the sounds when i go out of tf2) Then its the fps.. I am currently getting around 22fps on my map, on the original map i am getting 100fps with all high on settings. Is it any way i can optimize this? I have currently no idea how I optimize. I have many "secret" rooms outside of the map which may cause the lagg? Hope anyone here can help me with this Pardon my bad english and describing..
