Since newer versions of GZDoom and LZDoom removed the old JDoom method of using high resolution textures, a lot of these texture packages don't work anymore. It's an easy fix tbh but I can't really find any updated versions. So here is one I found with a lot of high res textures for Ultimate Doom, Doom II, Plutonia and TNT. I simply moved the textures into the right folder and now you can use them with modern GZDoom ports.
High Resolution Texture Pack for GZDoom and LZDoom
The newer ports of GZDoom and LZDoom removed the old method of JDoom's high resolution textures and made it a more simple task to do. Unfortunately this broke all the old highRes texture packs. So here is one I found which seems to be a very complete set. Credits go to the original creators ofc.
