OpenGL 扩展问题

[budweiser]

小弟用的是 Dell D630（显卡是 NVidia Quadro NVS 135M） 装的驱动是 197.16 系统： Xp sp3

在用 opengl 时基本上不支持 Opengl 扩展， 不知道是显卡确实不支持， 还是有什么设置不正确， 求解答。

通过 glGetString 函数得到如下信息：

GL_VENDER "NVIDIA Corporation"
GL_VERSION "3.2.0"
GL_GL_EXTENSIONS "GL_EXT_bgra GL_WIN_swap_hint "
GL_RENDERER "Quadro NVS 135M/PCI/SSE2"


还有 通过 glew 中的 glewInfo 得到如下信息：

GL_ARB_framebuffer_object: OK [MISSING]
--------------------------
glBindFramebuffer: OK
glBindRenderbuffer: OK
glBlitFramebuffer: OK
glCheckFramebufferStatus: OK
glDeleteFramebuffers: OK
glDeleteRenderbuffers: OK

glGenerateMipmap: OK
glGetFramebufferAttachmentParameteriv: OK
glGetRenderbufferParameteriv: OK
glIsFramebuffer: OK
glIsRenderbuffer: OK
glRenderbufferStorage: OK
glRenderbufferStorageMultisample: OK

GL_ARB_framebuffer_sRGB: MISSING
------------------------

GL_ARB_geometry_shader4: OK [MISSING]
------------------------
glFramebufferTextureARB: OK
glFramebufferTextureFaceARB: OK
glFramebufferTextureLayerARB: OK
glProgramParameteriARB: OK

在下不懂 GL_ARB_framebuffer_object: OK [MISSING]
是什么意思， 为什么它的子项都是 OK， 但它是 OK[MISSING] , 望解答.

Thanks.

你用OpenGL Extension Viewer试试看什么情况。

为甚么还会得到：

只有前面两个呢？？

和我之前问题可能一样，系统文件夹opengl32.dll文件版本太旧。

[budweiser]

我查了下 opengl 的 版本， 是 5.1.2600.5512 应该是比较新的 但情况还是那样

[gumbour]

你的开发环境中的opengl和windows的opengl是一个版本吗，会不会开发环境的opengl32.dll版本旧，你测试程序可能使用了开发环境的opengl而不是系统的opengl。

[budweiser]

原因找到了， 不是opengl32.dll 的问题， 是驱动的问题， 最新的197.16驱动有bug， 我rollback到了185.85版后没有问题了， 现在也支持很多扩展。

嘿嘿 多谢各位了。

[budweiser]

上面总结的还有点问题， 今天要用cuda， 但185.85驱动只支持cuda2.2， 为了使用cuda3.0， 我有尝试刷到了197.16， 结果发现opengl扩展还是支持的， 我推断，opengl扩展的支持在驱动升级中没有被复写， 也就是说197.16版本中可能根本就没有关于opengl部分的。但最好在驱动升级中不要卸载原驱动。

补充说了上面的，希望对有心人有用。
