It seems that glest needs full opengl 1.4 to run

[RogerW]

I downloaded glest 0.7.2, but crashed. Following was the error message:

Error(s)
Your system doesn't support Opengl version 1.3.
You may solve this problem by installing the latest video card drivers.

My display card is an onboard sis650,  fully supports opengl 1.0 - 1.3, supports 80% of opengl 1.4 ( as shown in "Opengl Extension Viewer", only GL_EXT_generate_mipmap, GL_ARB_imaging and GL_EXT_blend_func_separate not supported), it's really a little bit strange.

Desire any solutions or replies.

You are not right, Glest requires OpenGL 1.3 and the extension GL_ARB_texture_env_crossbar (or OpenGL 1.4).

If Glest says that your system doesn't support OpenGL 1.3 is that the version string returned by your 3D card is under 1.3.

The OpenGL extensions viewer in the first tab shows versions based on the extensions supported (it tells me that my card supports GL 2.0 and it doesn't exist yet), and it doesn't check all extensions (i.e. for OpenGL 1.1 it only checks 2 extensions and there are much more as you can see in the OpenGL specification), but the real version of OpenGL is shown on the second tab of the OpenGL extensions viewer.

Please tell me what GL version is displayed on the second tab as shown in this image:

Sorry abt this mistake. The actual extension version is 1.21.

Yes, I'm sorry but you won't be able to play glest with this OpenGL specs, have you tried downloading your latest video card drivers? If the card supports this extensions, recent drivers may upgrade your OpenGL to a more recent version...
