Download mod HD Reworked Textures v1.0 for Cyberpunk 2077 game.
HD Reworked - this project aims to improve the graphics by reworking game assets to better quality preserving original art style and good performance. Modification from author of The Witcher 3 HD Reworked Project. In general, the modification doesn't hit performance in any way if you have enough amount of VRAM (video card memory). Even if you run out of memory a bit, it shouldn't be a problem (and if it will, you can always easily uninstall the mod).
There are two versions of the modification, adapted to what the graphics card you have.
Cyberpunk 2077 HD Reworked Project Ultra Quality: contains the highest quality textures and gives the best visual experience. Highly recommended for 2K/4K displays. Game can use up to max 800MB more VRAM so most modern graphics cards should easy deal with it.
Cyberpunk 2077 HD Reworked Project Balanced: maintains high textures quality with lower VRAM usage. Recommended for graphics cards with less amount of memory. Game can use up only about 400MB more VRAM so basically everyone who can comfortably play the game can use this without experiencing any significant performance drops while having noticeably better textures.
Tested on game version v1.6.x
