Have 2 videos card, think dolphin is using slower video card

[zelda_fan]

My current computer has 2 video cards because i am using multiple monitors,

One is a gtx 970, and the second one is gt 640


I have a feeling that dolphin is using the gt 640 and not my faster video card because i am getting slow frame rates,



last year, I was running 1 video card on my system, the gtx 970 and windows 7, and it was working fine, no problems, i also was running it on ubuntu, but with 1 video card as well and worked fine,


but this year, I am running linux mint xfce, and 2 videos cards, i don't think linux mint is the problem, although, i really don't want to take out my second video card, just to test, i figured maybe people know here the problem



anyways, How am i able to check which video card the emulator is using, is there a way i can tell it to use my gtx 970?



help! i really want to play zelda, and i don't want to go back to ubuntu or windows, i also can't get rid of my second video card, i was planning on buying another gtx 970 but they are expensive at the moment



thanks!

It should print what graphics card is being used when you boot up the emulator in the yellow text on top of the screen.

So i guess it is using the gtx 970.

Here is what it says,

I am getting about 10-15 fps

What display is the monitor that has Dolphin running on plugged into?

Could be something silly with buffering over two GPUs

[zelda_fan]

II'm not sure which one, but i have just stopped and restarted on each monitor, and i still get the same fps on each monitor,

my linux system is using xinerama, i will disable that this weekend, and see how that goes, if not, i will remove the second video card and see how that goes, i really dont want to do that tho

If you're just doing a multiseat setup, assign each GPU to their seat and only one seat and you should be fine.

Have you tried a newer version of Dolphin than 4.0.2? There have been many performance improvements since. (Just make sure to enable the Hyrule Field Speed Hack in Game Properties > Patches for Zelda: Twilight Princess.)

Where can i get a newer version, I looked on the dolphin website but this is the only version for linux, i can't find any newer ones that this one

There is no patch for zelda in the game properties, it is missing, where can i download this, i remember in windows it was there, but i was also using a new version of dolphin,
but im on linux now

You'll need to compile it yourself.

On 4.0.2 and older, that patch is not useful, because old versions of Dolphin have a different way of solving the problem that that patch solves. The patch will show up automatically if you update to 5.0 or newer.
