Maizel, your ignorance & stubbornness on this issue is incredible, what part of "Dedicated Sound Cards Are Better than on-board sound cards" don't you understand?
You just can't read. I've capitalized the key words for you.
Seriously. drop the attitude, you don;t seem all too worldly yourself either.
I've used soundcards for as about as long as I have been gaming (20 years) , and on and off for the past 5 years.
And in these 5 years I have seen almost ZERO performance difference between a soundcard and an onboard audio card in EVERY game I've played. Sometimes even while runnign a decent 5.1 setup.
Yes, Dedicated soundcards can and mostly will sound BETTER. But in my experience they don't hurt game PERFORMANCE (again, not talking about sound QUALITY here)
Onboard audio is NOT the cause of the stutters.
If you want to believe that RO2 stutters because of a lack of a dedicated soundcard, go ahead and get one.
I'll illustrate this with an example which is maybe on your level.
If I have a bottle with water, and I puncture it, water will leak out. If I put some duck-tape on the hole, water will stop leaking.
Does that mean the cause of the water first leaking was lack of duct tape? No the cause of the water leaking out was the fact that the bottle was broken in the first place. The duct tape, was a fix though, but the lack of it, wasn't the cause.
