Heroes III in high resolution!

Well, 800x600 is a 4:3 aspect ratio, so you can increase the resolution while maintaining this proportion, and nothing will be stretched. It's just that the game is designed in such a way that the resolution is constant... Regarding the program - it is undoubtedly useful, but I set it to 16-bit, and I don't notice any difference.

But how can it not be stretched? It will be stretched.
Do you know what resolution is? If you stretch from 800x600 to 1024x768, what will happen? On a CRT monitor, there will be more pixels, and on an LCD monitor, several pixels will have to act as one, and the image will blur.
I may not have expressed myself correctly, but it is impossible to improve the picture in any way.
It's not very enjoyable to look at pixels the size of peas.

Many modern programs have special icons for a color depth of 32 bits. And the difference is actually quite noticeable.
