OpenGL Full-Screen "Exclusive" Mode?

Post by Rytz »

Hi:

I've been researching the topic of "exclusive" full-screen rendering with the hope that I can increase the performance of my full-screen windowed OpenGL canvas in wxWidgets. It seems the main performance boost comes from having direct access to the display and having compositing disabled (normally done by the window/desktop manager). In my case, I'm not trying to change the existing desktop resolution, just have exclusive rights to the secondary display.

While some of the links below are related to DirectX specifically, the idea is the same for OpenGL and non-WIndows operating systems. I have no clue about MacOS support. I did read that exclusive mode in Windows10+ has changed to actually be full-screen windowed instead with better optimizations.

Can anyone recommend any other sites, tutorials, or guides about exclusive full-screen modes or tricks to increase video/system performance while in full-screen "windowed" mode?

Thanks.
