game is designed around the bit more old-school approach so deliberately doesn’t have the modern day ubi/bethesda gps markers
Markers will appear when you are somewhat close to your target, that’s it, intention being to pay attention to quest log or npc instruction as i’ve understood
i don’t know if this still works/is compatible with the later GD updates, but you can try and see if this resolves your needs [MOD] Bigger Waypoints + Clean FOW Map
