i do have a question about using a different set of textures. I have a 4k map with its own textures though. I want to use reshade 3.0, since reshade has its on textures (set in the .ini) Is it possible to delete this phrase in the .ini. Will reshade work without setting the textures path?
Sure. All textures in that folder will be missing of course though and any effects depending on those won't work properly. It's a better idea to add your own path before the current one in the list of search paths. When searching for textures ReShade will pick yours instead of the default ones then if existing.
