Causeless Slowdowns? - Skyreeth - 11-22-2013
I had hoped to be able to alleviate this issue on my own, without needing to bother any of you folks with my problems, but I really am sort of at ends, here.
I'm not one for Wiimotes, they just don't feel comfortable in my hands- a sort of disconnected feeling too difficult to grasp on a spacial level. So, learning that Dolphin supports mapping Wiimote controls to a sensible gamepad, I set about getting my copy of Super Mario Galaxy working on my PC.
Much to my dismay, however, anything beyond the title screen results in a dip to about 26 FPS on average, which slows the game to an intolerable level. Poking about the forums for two days led me to find that, by all accounts, I should be fine! Yet the problems persist, heedless to my tinkering.
I fear that my CPU might be bottlenecking the speed, which wouldn't be entirely unexpected, and simply fuel for an upgrade- but I want to be certain I haven't made some grievous error. I'll check back frequently to answer any questions posed that could contribute to the solution.

Use OpenGL, Mario Galaxy doesn't like D3D11 at all, and your Nvidia + Vertex Streaming Hack will lend you much, much more speed.
And yes, your CPU is the bottleneck, but a more efficient GPU backend uses less CPU. Hopefully this can make it a bit more playable for you.

That-
Did beautifully. Occasionally I drop to 45 or so, but that's initial level loading and that's definitely more playable than 30. I very very much appreciate the quick response, as much as I like to find myself patient and fix problems without inconveniencing others, I just-
Well, sometimes innocuous things like this slip me by.
I'll look into, sometime later, a new CPU. I knew going into this that a first-gen i7 and a 'beta' Motherboard were desperately in need of upgrading.
Again, thank you so much for your time.

Yeah, once you upgrade to a newer i5 or i7, you won't drop below 60 at all with the rest of your PC being so well put together. Latest Development builds are actually a little bit faster than 4.0 as well, so you may find some better luck there too.
By the way, with a GPU like that, feel free to crank up the internal res and anti-aliasing a bit; it makes the game look absolutely jawdropping.

Your cpu is too slow. Upgrade and overclock. SMG is one of the most demanding games to emulate in the entire Wii library.
Edit: Damnit I forgot to refresh.
