Single Core mode is not used for regular gameplay but is usually required for TAS and NetPlay. Update: a few hours after release, a bug causing crashes with Windows 圆4 and Single Core mode was found by testers. Here is basically our hall of shame of graphics drivers, sorted by the number of issues we found, how hard it is to report issues to the company and how many bugs were actually fixed. More than that, on Android, OpenGL ES 3.0 support is extremely recent and only a couple applications on the Play Store use ES 3.0 features. It turns out very few applications use some parts of the OpenGL standard we need to rely on to accurately emulate a GameCube GPU.

Sadly, using recent, advanced OpenGL features also meant we got to discover how bad some graphics drivers actually are at doing their job. This rewrite was merged into the main Dolphin codebase a few months back and started to be used by tens of thousands of Dolphin users, either on OS X and Linux where it is the only viable graphics backend, or on Windows where it is available alongside our D3D11 graphics backend.

While this rewrite was needed for other reasons (it provides the foundations for very cool optimizations), compatibility with mobile devices and the future Android port of the emulator (now in beta) was one of the key goals.

In light of the recent announcements by NVIDIA and AMD in support of Linux for their graphics drivers, we would like to share with the world some of the experience we had developing our open source project, Dolphin, a GameCube and Wii emulator for Windows, Linux, Mac and recently Android.Īt the beginning of this year, after the successful release of Dolphin 3.5, Markus Wick (degasus) and Ryan Houdek (Sonicadvance1) started working on a rewrite of Dolphin's OpenGL backend in order to be compliant to the OpenGL ES 3.0 standard. All kinds of modern functions are simply not possible in D3D9. The D3D9 backend was as fast as it was because it simply didn't emulate certain effects. Its age means that many modern features are simply not available for it, features that Dolphin needs for GameCube and Wii emulation.
#DOLPHIN EMULATOR MEMORY CARD FILENAME INCORRECT UPDATE#
But Direct3D9 is very old it was released in 2001 and received its last update in 2004. On AMD and Integrated Graphics cards, it is by far the fastest backend. D3D9: Inherently Flawed ¶ĭolphin's D3D9 backend was mostly known for its speed. This is why the D3D9 backend was removed. With D3D9 removed, the developers can focus their effort on making the emulator better instead of pandering to the ever growing demands of a flawed backend. D3D9 is inherently flawed, and working around its problems wasted time and slowed development. While it was enjoyed by users, it was a source of endless frustration for the developers. For the longest time, D3D9 was considered Dolphin’s fastest backend and was a favorite of Windows users. You can continue the discussion in the forum thread of this article.Īs many people have noticed, revision 4.0-155 removed D3D9 as a video backend, leaving D3D11 and OpenGL as the sole hardware backends in Dolphin. However, as of 4.0-615, the Vertex Streaming Hack has been removed from Dolphin. It drastically improves OpenGL performance on Nvidia GPUs. Throughout Dolphin's history, developers have added various tricks to get more performance out of computers - one of them being the Vertex Streaming Hack, formerly known as Hacked Buffer Upload. One of the constant struggles in modern emulation is the battle between performance and accuracy. Any user caught in that situation will encounter a blackscreen.
#DOLPHIN EMULATOR MEMORY CARD FILENAME INCORRECT DRIVER#
Some driver versions tell Dolphin that they support buffer_storage, but actually don't. Unfortunately, that version check was there for a reason. As of 4.0-722 the version check was removed and buffer storage is confirmed to be working correctly. And thanks to an unrelated bug discovered later, the lack of buffer_storage wasn't detected in the initial testing. Because of this issue, even the latest drivers that support the function failed the version check and Dolphin didn't use buffer_storage on Windows. Since the Linux version of the driver reports its version correctly, the Dolphin devs assumed that the nvidia drivers would report it and used a version check to make sure ARB_buffer_storage was only utilized on drivers that actually support it. Update: There is an issue with the Nvidia drivers that kept buffer storage from being utilized properly on Windows: they do not report the driver version.
