Just something random I've never seen the answer to.
Does anyone know if using the HDMI audio on the ATI 5x series cards affects graphical performance at all? I haven't noticed anything directly, but none of the benchmarks tend to use audio either.
Also, would the audio quality setting make any difference either?
 
No if would not affect framerate. ATI 5000 series cards have a realtek audio chipset integrated into the card that they use. Your gpu isn't actually doing anythign different you are just using the integrated card audio chipset instead of the audio chipset on your mobo.

Also, would the audio quality setting make any difference either?

What do you mean?
 
The audio quality setting is within Windows itself. You can set it to differing quality levels like 24-bit 96000Hz. It's in the control panel under "Sound."
Back when the 5X cards came out, if you set it to the really high settings there were a boatload of issues with multi-channel surround. You'd have channels swapping around and lots of drop-outs.
When the Realtek 2.49 driver hit, that was more or less fixed...but I was wondering if that setting was affecting performance all along.

Lots of games have random hitching (usually people say they're "bad console ports") but I was curious if that setting might be affecting things like that, too.
 
It should not impace performance but it will cause sound issues if you set the sampling rate or bitwidth to high.
