Does not using the ports on GPU affect performance?

I recently got a new 5.1 surround sound headset and monitor and I am using HDMI as my video interface.

My GPU does not have any HDMI ports so I am using the HDMI port on the motherboard. I launch up Battlefield 3 to test my headset and I am getting absolutely horrendous performance on even the lowest settings. I'm getting 9 fps on the medium preset.
 
HDMi port on the mb erm then ur using the onboard gfx not the gfx card. Dvi is good as hdmi so use that on ur gfx card if u have it.

Are you saying you plugged it into the onboard GPU?

Yes. I think.

I do have DVI however I was using HDMI for a reasonable reason.

The monitor has an audio out port so I have my desktop speakers connected to my computer via the audio out on the monitor and the HDMI cable going into the monitor. The headset is plugged into the audio ports on the motherboard. I done this to save me faffing around with cables every time I wanted to change from headset to speakers.



I guess the verdict here is that I didn't know using the HDMI port on my motherboard would switch to onboard GPU :rolleyes:.

Could always use that command line program to change default audio. And then put the headset into the monitor

I cannot do that as to stop using the onboard GPU I have to use DVI which means no audio would be transmitted to the monitor rendering the audio out port useless.

Also, the headset has 4 audio jacks and needs to be powered via USB.
 
Sounds like you need a Y splitter for the sound. I have my headphones and speakers plugged into a Y splitter which is in the audio jack of my soundcard, so no crawling around under the desk or changing plugs is needed.
 
Okay, first, most gpu's have audio pass through in their dvi to hdmi adaptors. Every GPU I've bought since a 2900 or maybe 3870 has had this kind of adaptor and yes you can do audio through a dvi port. As with most things there are redundant connectors and the adaptor can pass through the audio(you need the right adaptor for the card as off spec stuff is usually gpu vendor specific.

Aside from that, I also can't remember the last motherboard nor case I've had that doesn't have an audio output at the front.

You will have on the motherboard a audio header, you connect the audio port from the case(like the front power/reset/usb cables). When you do this you have speakers plugged in around the back, and plug your headphone cable in round the front which will automatically switch your audio from the speakers to headphone.

DVI audio pass through has been around for years and front audio panel headers have been around for as long as I've been building computers(15+ years) and have never had a case or mobo that didn't support it.


There is also from what I recall a way for Intel users to use the onboard mobo outputs while using a discrete GPU for power, lucid software iirc. However it was always buggy, and iffy and generally offered lower performance anyway and was never worth it.

I know all/most AMD cards do the HDMI audio pass through(sometimes only on one of the dvi ports) for years, I don't know Nvidia cards do but would be surprised if they hadn't sorted it out years ago.
