笔记本集成显卡945，怎么启用 Photoshop 的 OpenGL 功能

我想启用 Photoshop 的 OpenGL 功能，但是 该选项 为灰色，无法打勾，不能启用。笔记本集成显卡是945，请问如何启用 Photoshop 的 OpenGL 功能。
“qingqing881114”辛苦了，就把分数给你吧。
经过一番埋头研究，最后还是由我自己来给出正确答案吧，希望对其他945们有所帮助。
945是不支持PS CS4的OpenGL功能的
1.要想启动PS CS4的OpenGL,你的显卡要支持OpenGL2.0
2.经过EVEREST检测，945只支持OpenGL1.4,同时可参考intel官网的说明。 http://www.intel.com/support/cn/graphics/intel945gm/sb/cs-021517.htm
对于OpenGL和945的说明，可分别参考以下intel地址：

Answer 1

只有nvidia8系列以上的显卡才能启用ps的显卡加速功能~~~~

你的945集显不可能支持，就算是最新的4500hd集显，也是不能支持的~~~~

只有拥有独立显卡，并且显卡支持物理加速的话才能开启ps中的opengl功能~~~

************************************************

不是945不支持opengl，是无法在ps中调用opengl！！！

adobe官方文档中有的
有关支持的显卡的列表, 请参见 TechNote “List of tested graphics display cards in Photoshop CS4”(TechNote kb405711*)。要在不支持的显卡上打开 OpenGL, 需要安装 AllowOldGPUs 增效工具。有关该增效工具的详细信息, 请参阅“Crashes occur, Photoshop CS4 won't open, or some features are slow and OpenGL is unavailable”(TechNote kb405064*)。注意, 尽管我们为您提供此增效工具, 但并不建议您使用它, 也不支持该增效工具。
