Wrappers

A wrapper is a reimplementation of a library, where the goal is to substitute the original API with a better-supported interface. It works as a drop-in replacement for the original library, since a lot of software usually bundled it as-is without any fine-tuning. Wrappers are most common for proprietary interfaces that are either abandoned or otherwise platform-specific.

See Emulation Accuracy page for more information about terms like "hypervisors", "simulators", "compatibility layers", "wrappers", "FPGA-based hardware cloning" and "software emulators".

'90s APIs

(Glide, DirectDraw 1-7, Direct3D 2-7, OpenGL 1.x)

During the 90s, many IBM-Compatible PC game developers used 3dfx's Glide API for hardware accelerated 3D games, which is compatible only with 3dfx Voodoo cards. Neither NVIDIA nor ATI supported Glide, hence a wrapper is needed to play Glide games on non-Voodoo hardware.

Games using older versions of DirectDraw or Direct3D can also benefit from wrappers, since their interfaces may not work properly on newer systems. Wrappers can also enable various overrides and enhancements, such as ReShade.

Comparisons

nGlide

Currently the best Glide wrapper, supporting all three public versions (2.11, 2.60 and 3.10) but it's closed-source. It originally only used Direct3D 9 until Vulkan output was added in 2.0, allowing it to work under Linux using Wine 2.10.0 and newer. nGlide also supports high resolution modes. See the compatibility list.

dgVoodoo2

Supports Glide 2.11, 2.45, 3.10, 3.1 Napalm, all versions of DirectDraw, and Direct3D up to version 7. Outputs Direct3D 11 and Direct3D 12 with different device types as wrapping output, such as hardware or software rendering.

WineD3D

Wine's internal wrapper. Wraps DirectDraw and Direct3D up to 7 into Vulkan and OpenGL. It works pretty well for running older Direct3D games, though it does not come with a Glide implementation of its own. A custom build is available for Windows here.

DXGL

Reimplements DirectDraw using OpenGL. It is considered alpha software despite many applications working.

glrage

Reimplements ATI3DCIF, an API from ATI used in a handful of games, and DirectDraw 2 over OpenGL. Originally designed specifically for Tomb Raider 1/UB patched with ATIRage patch, currently also supports Assault Rigs and Wipeout. Additionally, it applies some improvements, fixes and QoL changes to the games.

2000s and later APIs

(Direct3D 8 and higher, OpenGL 2.x and higher, Vulkan)

Modern Windows games will likely need one of these wrappers to work on other platforms. Usually these are not separate downloads, and will come packaged into compatibility layers like Proton, Wine, or CrossOver.

Comparisons

dgVoodoo2

Supports Direct3D 8-9. Outputs Direct3D 11 and Direct3D 12 with different device types as wrapping output, such as hardware or software rendering.

DXVK

It was originally designed to accelerate support for Direct3D 11 games running under Wine since a native implementation seemed unlikely. Today it is bundled with Proton. D9VK was later merged to add Direct3D 9 support, and D8VK was also merged to add Direct3D 8 support.

WineD3D

Wine's internal wrapper. Wraps Direct3D 8-11 into Vulkan and OpenGL. For newer APIs it has more bugs than DXVK. A custom build is available for Windows here.

VKD3D-Proton

A fork of VKD3D funded by Valve, which is more developed and has experimental support for DXR via VK_KHR_ray_tracing. Requires DXVK's dxgi.dll file to work on Windows.

vkd3d

Wine's work-in-progress Direct3D 12 to Vulkan wrapper.

d3d8to9

Not as versatile as dgVoodoo2, however it's the only wrapper that can wrap Direct3D 8 into 9. Its main advantage is Windows XP support, which dgVoodoo2 lacks. It's specifically useful for Windows XP running in VMware, since VMware's Direct3D 8 acceleration has graphical and/or performance issues.

Indium

A implementation of Metal on top of Vulkan, originally devolped by iglunix and later by Darling the open-source macOS compatibility layer.

MoltenVK

Developed by the Brenwill Workshop under the Khronos Group, it re-implements Vulkan for Metal. Emulators like Dolphin and DuckStation use MoltenVK instead of a native Metal renderer to support Apple devices.

Gallium Nine

An implementation of the Direct3D 9 library on top of the Gallium driver for Linux. By using calls native to Linux, applications running under Wine run "at near-native speeds" according to the maintainers. The caveat is that it only works on Mesa, not NVIDIA's proprietary driver.

Zink

A "just-in-case" implementation of OpenGL on top of Vulkan first introduced in 2018 by Collabora for the Mesa driver.
