Cry of Fear and etc. (

Xash3D/ Paranoia/ Cry of Fear and etc. ( Counter-Strike Neo?[Clarify])OpenGL is a 3D graphics API, which is used by the hardware renderers of 
GoldSrc and 
id Tech 2, as well as some 
Source 2 games.
Id Tech 2 engine (GLQuake) OpenGL
Features
- Experimented Reflections
- Transparent Water
- Rudimentary Shadows
Note:To enables Rudimentary Shadows r_shadows must be set to 1Note:Rudimentary Shadows in Half-Life were add in the 25th Anniversary update.- Texture Filtering
- Water ripple
Goldsrc engine OpenGL

Half-Life, using OpenGL.
Half-Life, using OpenGL.Features
- Colored lighting - Quake simply had monotone lighting
- Transparent textures - Glass can now be used in maps
- Water waves
Note:Water ripple from Quake replace by Water waves but not in Software Renderer the water ripple is used.- Texture Filtering - Quake (GLQuake) simply Texture Filtering
Since 2013 SteamPipe Update
- MSAA anti-aliasing - GoldSrc now natively support anti-aliasing, specifically, MSAA 4X, which is enabled by default on most modern hardwares. This will reduce the amount of jagged edges/staircases effect on the geometry.
Since 25th Anniversary
- Rudimentary Shadows
Note:To enables Rudimentary Shadows r_shadows must be set to 1
Source engine OpenGL
OpenGL uses togl converts DirectX shaders to OpenGL for macOS and Linux
Dxlevel 92
Dxlevel 92 is the OpenGL equivalent to DirectX 9 (Dx9)
Features
- Refractions with the use of a bump-map
- High-quality reflective water (used frequently)
- Softer edge dynamic shadows
- Normal-mapped lighting on models
- Improved-quality specular effects
- High dynamic range rendering (disabled by default)
- Phong shading
- Color Correction
- Motion Blur
Dxlevel 97
Dxlevel 97 is the OpenGL equivalent to DirectX 9 Shader Model 3 (Dx9.0c)
Features
- Lightwarp support
- High dynamic range rendering (enabled by default)
