OpenGL Architecture Review Board今天正式发布OpenGL 1.5。和OpenGL 1.4相比，OpenGL 1.5开始支持OpenGL Shading语言。不过，之前ATi合作伙伴Sapphire表示旗下出品的Radeon 9800 Pro已经支持OpenGL 2.0，SGI之前也宣布，采用Ati工作站图形芯片的Onyx4 UltimateVision也支持OpenGL 2.0。3Dlabs也宣布
过旗下WildCat VP系列显示卡和驱动程序也支持OpenGL2.0。现在看来最终用户和游戏开发者更加青睐OpenGL 1.5，而不是OpenGL2.0。
OpenGL1.5新增加功能如下：
Vertex Buffer Object: vertex arrays for higher performance rendering
Shadow Function: additional comparison functions for shadow mapping
Occlusion Query: asynchronous occlusion test for better culling
Non power-of-two Textures: for more efficient use of texture memory, including mipmaps
OpenGL Shading Language v. 1.0: as official extensions more specifically, shader objects, vertex shaders, and fragment shaders, all for use of programmable shader hardware
