Re: Sound stutter in Crysis only
The reason why you're getting stuttering with certain audio hardware is because Microsft didn't implement DirectX audio hardware management within Vista so instead they decided to do it by software only which puts much more work onto your system. In XP this stuttering doesn't exist because audio hardware management exists. Software audio acceleration is much slower than hardware which is why you end up with the weak sound performance. This can be fixed however through a patch which the developer can create. Crytek is pretty lazy so I don't expect much from them.
Some upgrades or refined tweaking can reduce the problem until Crytek gets off their rears.
