ofShader warnings when running in Windows 10.

[kirbyszeto]

I have been writing/compiling my app from Windows 7, VS 2017.
Running the app locally works fine.

If I try to run the compiled app from a Windows 10 machine, I get a series of ofShader warnings, then the app stops rendering. I can see notices running in the debug window, so I know it is still running. just not rendering anything.

warnings look like:

That shader needs to be updated to GLSL version 150 or greater to work in your project.

Thanks! is that something updated through the device driver?

My bad, there is support for OpenGL 4.0 in the source code.
Try using this code to create your window in main.cpp

ofGLWindowSettings settings;
settings.setGLVersion(4,0);
settings.width = 1200;
settings.height = 700;
ofCreateWindow(settings);

When I do that, I now get this error:
