Just want oppinions on what would be the best options with HD mod for Heroes 3.

I have a Full HD screen (1920x1080) and using that resolution makes the game HUD too small in my oppinion. what would be better options to use?

I prefer 800x600 myself.

I go for 1180x644 myself because it both looks like the original gameplay and also benefits from the GUI improvements of HD mod. Lower than that, GUI can't use HD Mod's additions.

Ok thank you both.

You can mix the "source size" and "mode" options to scale the rendering to your liking while keeping the HUD at an acceptable level and still have the increased viewport

For example, on my 1680*1050 monitor I use

Mode: True (stretchable) GDI
Source size: 1369x856
Filter: Bilinear Sharper 2X M
