Has anybody else had problems with DOOM on Steam? For some reason the game takes a long time to load up to the main menu and even when booting into single player or multiplayer. When trying multiplayer before the screen went black and then the loading screen appeared and the sound was jittering and lagging, the loading percentage was going really slow after waiting almost 5 mins for it to load, so I ended up ending the process in task manager. Any ideas? Specs in sig.
