That is why I'm reporting this. I have no performance issue with any other game I've tried other than this one.

The difference in requirements is quite drastic for just this one game. Just saying I think it might be something that could be optimized/fixed in Dolphin. Before buying a new GPU (which will still be an AMD GPU that I'm going to be using with FOSS drivers, I'm kind of getting the vibe that you guys don't support or take kindly to people using free drivers?), I figure I might as well report it here.

It's not reports with the free drivers? We use mesa for fifoci and they've fixed bugs for us before.

The problem with reporting performance issues is that every game acts differently, and I honestly don't know what processor you're using, i don't know how good the Radeon mesa drivers are or anything else. There's not enough information to even look into things outside of going and finding the game and seeing if it's slow for me.

i7-2700K, it does not hit 100% usage when playing the game.

This was my hope of course, a programmer with knowledge on how to debug and solve problems in Dolphin could maybe take a look on his system, even if his system is quite a bit different it may still show valuable info.

Well, with Dolphin you can't really hope for 100% CPU usage. The GameCube itself is a single core machine, and splitting CPU emulation up between cores simply can't happen. We do split the GPU emulation into a separate core by default with the dualcore optimization, though. If you're seeing anywhere between 25 and 50% CPU, you could still be CPU limited. If the game requires EFB Copies to RAM, it's also possible that the CPU/GPU synchronization is the bottleneck and there's nothing that can be done at this time.

the i7-2700K, while still a good CPU, isn't enough to run every game. It's entirely possible that nothing is wrong, and the game is just hard to emulate and general optimizations in the future will help it. The other possibility is that it's hitting some inefficient codepath of Dolphin that needs attention. But, without someone taking a look at what the game is doing, there's no way to actually tell which it is.
