Certain games will play very slowly such as fear 3. Even the intro videos like logos and stuff, even the main menu will run at a very low frame rate. Now this is nothing to do with my hardware. I used to use game prelauncher to diasble all services and startup entries. This would cause my games (those few that mysteriously lagged) to play fine. but my trial of game prelauncher has run out and now my only option is to go to msconfig and run diagnostic mode. This terminates the problem service but I can not for the life of me get the windows audio service to start in diagnostic mode So does anyone know which service causes this lag problem in windows 7? Or do you know how I can enable the windows audio service in diagnostic mode (I have tried enabling the deps but nothing works). Any help appreciated.
