Hello

I just got a Acer Nitro 5 laptop (AMD build) and am downloading my older games. When I try to play Heroes 3 / Chronicles (or any older game for that matter) the display seems to be stretched horizontally messing up the image. I tried messing around with some of the AMD settings to turn GPU scalling on and perserving the aspect ratio but that doesn't seem to change any thing.

I was able to HoMM3 running with the HD Mod but I'd like to also be able to play Chronicles.

Hardware:
Model: Acer Nitro AN515-42
CPU: AMD Ryzen 5 2500U with Radeon Vega Mobile Gfx
RAM: 8GB
GPU: AMD Radeon RX 560X

Display settings:
1920 x 1080
125% Scaling (If I change this to 100 it doesn't fix the issue either).

Does anyone have any suggestions?

You can play the Heroes Chronicles as custom campaign using the HD Mod: https://www.reddit.com/r/HoMM/comments/3r9785/heroes_chronicles_in_hd/

You can try GL Wrapper it should help you.
