Me and a buddy wanted to play Paper Mario TTYD over netplay, by having one of us control mario and the other control the partner, and vice versa. Just for fun so we could discuss the game and have laughs at battles gone wrong, etc. This could be applied to alot of single player games, similar to passing the controller around.

Actually I suppose it could apply to some mario party games as well :3

I want dolphin to support dual graphics so i can get better performance if i combined my integrated apu graphics with a dedicated video radeon hd video card

Not going to happen afaik

Combining an APU with a dedicated card doesnt sound like a great idea anyways. I am not an expert on such things but I thought that if you gain 2 cards together like in SLI or Crossfire, then the slowest card dictates how fast, etc the faster card can operate. You essentially limit the better card to the slower card's performance. And if that is an APU, then that would likely be worse than just your dedicated card.

Others feel free to weigh in if I am off. It wouldn't surprise me :p

There are some not-quite-crossfire solutions which can be done with APUs, which don't slow the dedicated card down, but I don't know how effective any of them are.

Either way, dolphin is unlikely to support multi-GPU systems simply because by the time that enough code was running to properly synchronise the GPUs, they'd be running slower than just one of them would be.

Dolphin already supports SLI, don't know about crossfire, though. Just check OpenCL texture decoder, it speeds it up a lot.

**AnyOldName3** · 06-03-2013, 08:32 AM **#709**

The OpenCL texture is much slower than the regular one, and it isn't evidence of SLI support even if it was.

Not possible afans (as far as neobrain says).

Very well. You're wrong and that makes no sense.

Heterogenous crossfire is just as effective as homogenous crossfire. It splits the workload between the two gpus effectively and produces a small speedup over using just the faster gpu.

Usually. Not always.

What? Yes it is.

He's completely right. Dolphin does support SLI. It just doesn't benefit from it, except openCL apparently (which makes sense now that I think about it).
