Does not using the ports on GPU affect performance?

[valkynaz]

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.

Are you saying you plugged it into the onboard GPU?

Yes. I think.

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.

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 .

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.

Perhaps buy a speaker system which allows you to have Headphone In?

I think you misunderstood the purposes of the two devices. The headset is to be used for gaming and the speaker system for music/films.
