I have a big problem with OpenGL and DirectX 9 graphics devices.
The problem is that I can not switch to full screenmode, if I set the parameter "structSrrlichtCreationParameters::fullscreen" to "true".
The window is set with a resolution of 1024x768 for the window mode.
I have set the resolution of 1024x768 over the parameter "structSrrlichtCreationParameters::windowsize".
Now, when the application starts, the window is set as a pop-up window in the upper left corner (x, y = 0.0) with a resolution of 1024x768.
But it does not go to fullscreen.
When I start the application in windowed mode, the window is not centered on the desktop.
When I start the application in fullscreen with directx9, a message comes that the DirectX9 device is not supported, but in windowed mode this message does not come up and the window starts as a normal window in the upper left corner (x, y = 0px, 0px) a resolution of 1024x768, but not centered on the desktop.
Is the dricetx9 device supported or not?
I have the irrlicht-sdk compiled with Win8.1-SDK under VisualStudio2017.
Then i have installed the "Microsoft DirectX SDK (June 2010)" for directx9 support in irrlicht.
My graphics card is: NVIDIA GeForce GTX 1060 6GB and driver version 390.77 (up to date).
My operating system is Windows10-64Bit
I never had any problems with it, but only since this computer (that's new PC, about 6 weeks old).
Best regards
