Dolphin, the GameCube and Wii emulator - Forums

When I play with iZ3D in 3D the emulator has to process the scene twice instead of once, but it's using the same core to process both scenes which drops the frame rate to half of original when gaming in 3D.

Is there a way for the emulator to use separate cores for each scene? That way both scenes are running at full potential of each core, and 3D gaming is as smooth as 2D.

Nope.

... what?
Rendering is done by the GPU, not by the CPU.

You clearly have no idea how rendering works. Nearly all of the actual rendering work is done by the GPU.

Edit: Damn, he beat me to it.

Well, if you get another GPU (Same model), and enable Crossfire/SLI, the game will use two graphic cores if that's what you meant...

I thought SLI/Crossfire dosent support dolphin

Depends what you mean by "support". I would say yes it does "support" SLI/Crossfire in that it will work with an SLI/Crossfire setup but it won't improve performance.

I'm not sure I'm comfortable using the word "core" to describe a gpu. Core tends to imply CPU or at least a general purpose processor. Also it refers to processors that are on the same die, whereas two GPUs in SLI/crossfire are physically seperated.

*goes to switch "rendering" with "processing"*
There, is that better?

With a 560ti the frames drop to half when in 3D mode which leads me to believe that this is a CPU issue. Perhaps the processing needed is being doubled in 3D for one core so if it got split for two cores then one core wouldn't need to process both scenes at the same time.

I see, nevermind then.

Not really, they mean nearly the same thing in this context.

Doubt it.

How are you measuring the framerate? The drivers may not be properly set up for something like dolphin (which would cause the framerate to be halved since 60 fps in stereoscopic is 30 real fps). What kind of equipment are you using? What's your monitors refresh rate? What are the settings you are using for IZ3d?

If by "processing" you mean "cpu load" then no.

or you can download the iZ3D driver and try it yourself:
