There is a C++ application and the app has two windows;Can I use opengl version1.1 in one window and use opengl version 3.3 in another window?

What you’re really asking is, with one application, can I render to two different windows using two different OpenGL contexts, where each context has been created targeting a different OpenGL version?

This is a function of your graphics drivers. Probably so. Try it and see:

• Create windows A and B
• Create GL context A targeting OpenGL version X.XX
• Create GL context B targeting OpenGL version Y.YY
• For all frames…
  • Bind GL context A on window A
  • Draw
  • Bind GL context B on window B
  • Draw

@Dark_Photon Thanks! I will try it .
