HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

He actually needs EVIL )))
That's why I asked if it's possible to enable the same full-screen stretching as in the original game in the New Dawn expansion, or not.

By the way, I have a 1680x1050 widescreen monitor on my desktop. I enable the 32-bit True (stretchable) mode with 1062x664, and everything is fine with the resolution in the game.
But if I want a smaller resolution, around 800x600, there isn't even an option to choose that. (885x664 with black bars is the same as 800x600). There used to be an option in the menu by default for 8xx-6xx, but it disappeared somewhere.

Either I don't understand something, or you don't.

Let's say we have an image of 864x664:



We need to stretch it to 1366x768.

1.) We can stretch it while preserving the proportions like this:



2.) Or without preserving the proportions like this:



But the (stretchable) mode allows you to change the original resolution while keeping the same height of 664.
3.) The result of proportional stretching from 1181x664 to 1366x768 looks like this:



Option 2.) is not available in (stretchable) mode, but can you really prefer that monstrosity (2.)) to option 3.)?

A fourth option does not exist! That is, it is impossible to have neither equal proportions nor proportional stretching without black bars, except perhaps in some other reality.

If you still prefer the monstrosity (2.)), then please:
choose NOT (stretchable) mode and one of the STANDARD resolutions.

Yes, things like possible desynchronization when updating a version must be announced, and it's even better to duplicate it in the forum, as there is a lot of frustration in online games.
The same applies to incompatible passwords/saves with new versions and general incompatibility with older versions.

I understand.
But I couldn't have predicted the desynchronization, and if I exclude it with incompatibility, then frustration number 2 appears.
