Thank god this shit is fixed now and I can enjoy doom3 and you guys will be able to. Here is what you need to do double click my computer then right click on the harddrive click properties and then click policies and uncheck enable write to caching on the disk and hit apply and reboot computer. this was the problem let me know if this fixes it and once again you are welcome I can tell you from my experience everything works fine and has been enough said time to play doom L8TER

Well, I'll be damned...worked like a charm. Thanks much

now when you say the shuttering issue you mean the constant flashing of the screen while playing?

He means the sound stutter/looping thing
