OpenGL Core 是一种后端，能够在 Windows、macOS 和 Linux 上支持最新的 OpenGL 功能。根据 OpenGL 驱动程序支持情况，其版本范围从 OpenGL 3.2 到 OpenGL 4.5。
有关如何在编辑器或独立播放器中将 OpenGL Core 启用为默认图形 API 的信息，请参阅覆盖默认图形 API。
OpenGL Core 具有以下最低要求
macOS 10.8（OpenGL 3.2）、macOS 10.9（OpenGL 3.2 至 4.1）
Windows，NVIDIA 自 2006 年起（GeForce 8）、AMD 自 2006 年起（Radeon HD 2000）、Intel 自 2012 年起（HD 4000 / IvyBridge）（OpenGL 3.2 至 OpenGL 4.5）
Linux（OpenGL 3.2 至 OpenGL 4.5）
编辑器和独立播放器的 macOS OpenGL 后端支持 OpenGL 3.x 和 4.x 功能，例如细分和几何着色器在 GPU 上运行的程序。 更多信息
参见术语表。
但是，由于 Apple 将 OS X 桌面上的 OpenGL 版本限制为最多 4.1，因此它不支持所有 DirectX 11 功能（例如无序访问视图或计算着色器）。这意味着所有配置为针对着色器级别 5.0（使用#pragma target 50）的着色器都无法在 OS X 上加载。
因此，引入了一个新的着色器目标级别：#pragma target gl4.1。此目标级别至少需要 OpenGL 4.1 或 DirectX 11.0 着色器级别 5（在桌面上），或 OpenGL ES 3.1 + Android 扩展包（在移动设备上）。
新的 OpenGL 后端引入了许多新功能（以前主要仅限于 DX11/GLES3）
