Dolphin slow on good pc

Dolphins requirement vary wildly with different games - some require hard to emulate features, others don't need them so they can be turned off. There are some games that cannot run everything at full speed on even the most expensive, overclocked, super cooled high powered desktop CPU. There simply isn't a value that's "enough" for everything.

Also remember many benchmarks (like passmark) are not a good epresentation of the load dolphin puts on the CPU. It's entirely possible to have a CPU score lower on that, but be faster for many titles in dolphin. No single metric can ever measure how "good" a CPU architecture is, as they all have different strengths and weaknesses.

For example, the Intel haswell series provided a significant boost to dolphin, but a much smaller increase for other metrics (like the passmark benchmark)

I understand that CPU requirements vary greatly from game to game, and that Passmark’s single thread rating isn’t an ideal measure of Dolphin performance, etc. What I have noticed is that despite these caveats, CPUs that score over 1800 on that test have never had a problem with any game in my Wii/GameCube library. I don’t own every game, but I do own some that are notorious for performance issues in Dolphin, such as SMG.

If you know of games that trip up CPUs that score 1800 or higher on that test, let me know. I’ve helped a couple friends build budget Dolphin rigs based on Pentium G-4XXX series CPUs, which score between 1850 and 1950 on the Passmark single-thread test, and they haven’t complained, but maybe they just haven’t tried a more ‘difficult’ game than SMG yet.

My current Dolphin rig uses a stock-clock i5-7600, wich scores ~2300 on that test, so I can no longer determine if a game I’ve never tried before will run adequately on a CPU in the 1800 range. It’s an imperfect guideline for the reasons you mention, but I haven’t personally seen any counterexamples that make it a bad rule of thumb.

Have you tried playing the game when "Synchronous (Ubershaders)" is ON?

That setting is tied to GPU performance, not CPU.

It would also simply choke your GTX 960 if you even try using higher IRs because of how intensive the setting is.
