Dolphin has two performance related configuration windows: Dolphin configuration and Graphics settings, in addition to applying settings per game via their GameINI. Dolphin is a very demanding program, so configuring Dolphin the right way is very important to run titles smoothly.

System Requirements

Every game has different requirements, some titles may require a powerful computer while some other titles may not. Generally, these are the minimum recommended requirements for Dolphin.

Dolphin Configuration

Dolphin is shipped with default settings for the most optimal performance, you do not usually need to change anything on your first time Dolphin setup.

Enable Dual Core

Provides a significant speedup on modern systems. Recommended on most titles, though may cause issues like crashing or graphic issues on some titles. Refer to this page for a list of titles that require disabling Dual Core.

CPU Emulator Engine

JIT Recompiler is the fastest engine and is recommended on almost all titles. There are a few titles that work better with different emulator engines but unplayably slow.

Audio

DSP HLE is the fastest DSP Emulator Engine. It is very reliable, and only a few titles still have problems with it. See DSP LLE for more details. OpenAL is faster backend. Recommended on almost all titles.

Graphics Settings

Some of these settings will improve emulation compatibility in exchange of PC performance.

General

Enhancements

The emulation can suffer slowdowns from extreme multiplier options in Internal Resolution, Anisotropic Filtering, and Anti-Aliasing settings. Start with minimum option like "1x Native (640x528)", and go up from there until you can find the highest setting without slowdown. Keep in mind non-1x options may cause graphical issues in some titles.
