I have just noticed that you have V-Sync on. Based on what I've read here, this can apparently cause issues and slowdowns. What happens if you turn it off?
Newer dolphin development version cause games to run slower on my pc?

I don't understand it, either. I detailed my problems here. My FPS drops from 40 to 25 with that PR, and I can simulate the performance drop in 4.0-8979 by unchecking the Fast Depth option.
I don't know why, but my GPU seems to be using Slow Depth instead of Fast Depth after that PR was merged, which kills my performance in situations where the game is GPU limited. My guess is that whatever the PR does to detect whether it should use Fast/Slow Depth doesn't work correctly depending upon your GPU/driver, which causes it to use Slow Depth in situations where it shouldn't.

Dolphin uses 2 cores to emulate the GC CPU and GPU, but GC/Wii consoles are not threaded, so Dolphin can't increase its performance by using more cores, either. Dolphin performs poorly on AMD CPUs because AMD has poor per-core performance, which they try to compensate for by putting 6+ cores on their CPUs. It's a decent strategy for many applications, but it doesn't work when a program needs high performance on individual cores, which is what Dolphin needs. 03-01-2016, 09:46 AM

That's inherently impossible because Dolphin is an emulator, not a PC game. The FAQ has a much better explanation for why Dolphin only uses 2 cores roughly (which explains why single thread performance matters). It's not that Dolphin is not optimised for AMD CPUs. It's that they have awful single thread performance compared to Intel. 03-01-2016, 11:54 AM
The latest Dolphin is the fastest version . The reason why it isn't the fastest version for you is because you're still using Direct3D11 (as you showed in your screenshot)
Dolphin has Direct3d12 atm and it's way faster than any other back end Laptop: Mini PC :: 03-02-2016, 03:37 PM

Dolphin is in a quite good shape, there are tons of crazy optimizations done, but don't expect us to do something impossible... 03-03-2016, 02:14 AM

I wasn't in the know that you couldn't do that, or that it would even be considered "impossible", but thanks anyways. 03-03-2016, 02:17 AM
Dolphin is more than 10 years old, and with the regular commits and with the progress reports on the blog, you could have guessed it is already pretty optimised
and actually the most important thing the FAQ (also on the official website) mentions is to avoid AMD CPUs, which give bad performance. 03-03-2016, 10:42 AM
