Null: This graphics backend is for debugging only and does not render any graphics.D3D12: D3D12 is slightly faster than D3D11 on some onboard graphics chips, but may be slightly less stable in rare circumstances.Only available on Windows, but generally runs well on every kind of GPU. D3D11: This backend is a middle ground between most other backends.Not recommended on current RDNA2 Android devices as they do not ship a dedicated OpenGL driver, and instead rely on ANGLE. Very slow on AMD based graphics on Windows, but can be usable on Linux. OpenGL: Typically considered Dolphin's slowest backend, but is generally very stable.Not recommended for Intel devices, and Adreno (Snapdragon) graphics vary per the driver as to how well they will support Vulkan. Vulkan: Generally runs great on NVIDIA and AMD graphics chips, including mobile RDNA2 devices.Your choice in video backend may greatly alter how much performance you get depending on your graphics card. We'll try to cover the major cases here, but your performance will vary. As such, some of the Graphics Settings may have a higher impact on certain GPUs than they do on other GPUs. While Dolphin doesn't particularly need a powerful graphics card, it does want efficient drivers that can handle things that aren't commonly used in modern games. Raising the Emulated CPU Clock Rate makes games more demanding to run, but may cause them to run better if the emulated title was lagging internally. This setting can also break games if they are relying on specific CPU timings, and should be disabled if new problems suddenly crop up after enabling it. In many cases, games have a built-in frameskip for lagging, which will lower the requirements of running that game drastically. By lowering the Emulated CPU Clock Rate below 100%, you can cause the game itself to lag. Changing this option alone may slowdown your performance by tenfold or more.Įmulated CPU Clock Override: This is one of the most powerful tools for gaining performance on weak devices. It is set to the fastest option by default regardless of whether you're using Desktop or Android Dolphin builds. Due to a timing quirk in these games, DSP-LLE is required for proper audio.ĬPU Emulation Engine: This setting should never be touched by general users. The one exception to this is a case where Dolphin will automatically use DSP-LLE - Neo-Geo Virtual Console titles. DSP-LLE is typically used for homebrew titles and debugging. DSP-HLE is many times faster and causes no risk of issues in 99% of titles. Dolphin will usually disable Dual Core in games that are especially sensitive to CPU GPU desyncs.ĭSP-HLE vs DSP-LLE: Most users should never have to change between DSP-HLE and DSP-LLE. The most common downside to this performance boost is the risk for random "Unknown Opcode" issues and the associated crashes. May cause various random issues caused by splitting the CPU and GPU threads onto different cores. Settings that do not pertain to performance will not be mentioned in this guide.Įnable Dual Core: A powerful option for gaining performance that has no downsides some of the time. In this guide, we'll go through some of the easiest ways to gain performance and note the downsides of the various performance hacks in order to help identify when they should be disabled for stability. Faster computers may want to disable some of the performance hacks for more stability, where as slower computers and many mobile devices may want to sacrifice stability for even more performance. All other manufacturers are not generally recommended.ĭolphin's default configurations are centered around a mixture of performance and compatibility. High-end Mali graphics solutions may also provide playable framerates.
