=== Bounding Box Slowdown on NVIDIA Cards === | |||
On OpenGL and D3D11, NVIDIA cards are abnormally slow during bounding box effects even at very low internal resolutions. They get dramatically slower as the internal resolutions increase, even though comparable AMD graphics cards suffer no slowdown at all. This is due to Dolphin hitting a slow path on those graphics cards. Thankfully, the D3D12 backend doesn't run into this issue on NVIDIA cards, and provides performance equivalent to likewise graphics cards. | |||
It is recommended that NVIDIA users on Windows 10 use {{revision|4.0-9308}} or newer and the D3D12 backend to prevent slowdown and CPU/GPU desyncs caused by said slowdown. For non-Windows 10 users, a similar speedup is being worked on for OpenGL. https://github.com/dolphin-emu/dolphin/pull/3831 | |||
=== Problems When Using Older Graphics Cards === | === Problems When Using Older Graphics Cards === | ||
Revision {{revision|4.0-5143}} introduced changes to the Vertex Loader JIT implementation of Bounding Boxes. This change requires GPU-specific features that are not present on older GPUs (older than 3rd quarter 2012). As such, graphics cards without Direct3D 11 or OpenGL 4.3 support are no longer supported. In essence, only computers with GPUs: Nvidia GeForce 400 series and newer, ATI Radeon HD 5000 Series and newer, and Broadwell integrated GPUs (HD Graphics 5300+) are supported by Dolphin for games requiring certain bounding box implementations. Using newer revisions with unsupported GPUs will lead to graphical glitches and softlocks. If game-breaking bugs are experienced, use revision {{revision|4.0-5124}} or lower as a workaround. For more information, refer to {{Issue|8405}}, {{Issue|8505}}, {{Issue|8270}}. | Revision {{revision|4.0-5143}} introduced changes to the Vertex Loader JIT implementation of Bounding Boxes.
