For open source development is a nightmare, NDA things can not be released with open source software, so this road is a dead end. Is there no way out?Try 2:opengl QuadbufferOpenGL itself provides Gl_left_back, Gl_right_back, Gl_left_front, and Gl_right_front four buffers, built-in three-dimensional support. But the drawbacks of this approach are also obvious:

paravirtualization form requiring guest-specific drivers, it is obvious that virtio is restricted to areas where it matter most, so disk and network subsystems are prime candidates for those upload drivers. let see if, and how, both Linux (centos 6 x86-64) and Windows (win2012r2 x64) are affected from that paravirtualized goodness.Testbed and Methods

execution of the same drawing instructions will be very slow. After my test, in my 6600GT graphics card, using the official 93.50 driver, rendering the same screen, with the selection mode after the average speed of less than 10%, that is, more than 10 times times the rendering time. Simpler graphics render performance is also less than 30% of the normal rendering. The result is a serious delay.
At first I thought it was my program optimization problem, but even though all objects use a display
