我正在用 C++ 编写一些 OpenGL 3 程序，现在我的笔记本电脑 Lenovo Thinkpad e320（Intel HD Graphics 3000）出现问题。它在我的 PC (ATI Radeon HD 5870) 上运行良好。
错误附近的代码如下：
bool GLWindowCreate(const char *title, int width, int height, bool fullScreen){
...
g_hRC = wglCreateContextAttribsARB(g_hDC, 0, attribs);
if (!g_hRC || !wglMakeCurrent(g_hDC, g_hRC))
{
LOG_ERROR("Creating render context fail (%d)\n", GetLastError());
return false;
}
...
}
所有编译都很好，我在日志文件中看到了这个错误。
我正在使用 Windows 8（在 PC 和笔记本电脑上）。笔记本电脑上的显卡支持 OpenGL 3。我找到了一些关于我需要关闭硬件加速的相同问题的答案，但似乎在 Win 8 中没有办法做到这一点。
