Massive performance drop in recent builds

[Xtreme2damax]

Well up until recently DSound was working fine regardless of what Windows operating system. So DSound is deprecated just like Dinput and Direct2D/GDI etc..? Regardless DSound was working fine but some commit changed that and I don't feel like tracking which commit due to insufficient bandwidth, caps and lack of time to bother. Even OpenAL is broken afaik, tried that backend recently and audio is terrible compared to XAudio2. But I agree DSound is a bit redundant when XAudio2 works fine and XP/32-bit is unsupported now so no need to keep a dying horse around that doesn't run as well as it used to. Not that I care since I use XAudio2 which works fine but I was testing the other backends for some reason and found DSound to have a severe performance regression that lags the emulator.
