Hi all!

One strange thing just happened to me and i think its good to have it posted somewhere. After inserting a new hard disk in my PC, and fresh copy of windows and 3dgs, i copy my game files to new hard disk. I started the game, change one level, when... my game has slowed down about 30fps. Wtf!? OK let's check graphic driver, directx version and some other things... hmm everything is ok.
Let's back old hard disk, maybe something is wrong with my code. I start game from old hd, when... everything work perfect. Ok lets copy again complete game folder on usb flash, put back new hd, start game... problem is still here.
I open debug window "time for script execution" grow up 10 times when slowdown start. I lost two day to find a reason why this happening. Finally i isolate problem in play_music function, and every time when player change level, code for playing new music start and then "time for script execution" increase from 3-4 to over 30. I install ogg codec and problem is solved.
As things stand now, this mean my game will run like shit if ogg codec is not installed on end user machine.
I noticed the almost same "Engine slowdown syndrom" happening if i load level with missing action or model-texture error.
Whether anyone had a similar experience, or anything else to say on this?
