I'm talking about MIP.
When saving in Photoshop using the Nvidia plugin, there's an option to choose how many of these images there will be (I don't know how to do it through another program: most likely, the MIP is set to 0 copies by default, although I'm not sure). Also, in the configuration settings, in the game profiles, there is a value for MIP (zero is the most optimal option), but this is not so important.

That's the thing, I'm using PWL, and I insert hero icons and all new images using the standard method - through the map editor (just like models), the format is standard .PSD - it supports transparency, and it's a standard format in Photoshop. When exporting, it automatically modifies the .xdb file, and I still don't understand what to change there. The result is there - everything works!

Changing the screen resolution is, of course, a good idea, but there are mods that work perfectly at any resolution (I've given examples). I once figured out why RageButton, and not NecroButton, suffered this fate. If you wish, I can also fix it on your map.
2Ment You don't need to change the screen resolution - any resolution will do, you just need to change the image quality (I think that nowadays computers can easily handle the game at high quality). And what's so bad about it - it's just an image, nothing terrible if you don't see it - it doesn't affect the game in any way. And it's better to scrap the mod altogether - it's buggy.

I've figured everything out... only one thing is unclear - in Shio, after talking to Kha-beleth, the hero automatically attacks an army of 5,000 demons, having only about 600 (plus an archdevil) and no magic or developed skills... it seems that winning the battle is unrealistic.

It's a flaw. Ideally, the demons should join him - then Brittiga and Arnyel (during the running around, he buys a huge army). I planned to make it dependent on Agrael's charisma and saving the artifacts obtained. But in principle, I was killing him - with a completely filled reserve (elementals + elemental belt + a bag of gold when hiring) - there is enough meat, we buy spells, artifacts too, and we level up on the elves (the hero's level remains the same).

The map has not been tested by anyone other than me, so there are many errors in the scripts. I may fix them over time. Thank you to everyone who pointed out the obvious errors!
