I'm having issues with my computer related with scaling when using different resolutions other than the native. So I started to wonder, in PCs, is scaling handled by the card driver or the game engine? Does it depend of what engine we are talking…

What's the difference between using hardware-accelerated APIs and the OS's drawing API?

On Windows, I can do drawing with the OS API without OpenGL or D3D. The code I am writing will make calls to a device driver and tell the GPU what to do regardless, right? How is using OpenGL different exactly? Do these libraries have code that will…
