There’s a new update for Tomb Raider 1-3 Remastered, which includes updated textures which will make keys more visible in TR1 (hurrah!) and improved lighting in those dimmer areas of the games overall (another hurrah!).
In addition, the developer has also added some missing HD textures across the board (perhaps those ones players on the Epic Games Store noticed), and sorted the textures that would periodically disappear depending on how the player had their camera positioned.
