Turn off multiprocessing. OpenGL doesn't work with it. Otherwise update your graphics driver.
Thx ya comment sir
i already update Graphic driver but same happening
other ways how can i make workin good OpenGL sir?
whats wrong with this ..
i dont hava choice ? just turn off? (T^T)
turn off Multiprocessing it's influence for rendering speed?
Correct. Element 3D does not use multiprocessing. It uses the display card's processor to render. Because you only have one display card, you can't multi-process Element 3D content. At best, having MP on while rendering Element 3D content will slow down your renders. At worst, it will cause an error, like you have seen.
Thank u for ya comment!
