Next week Bethesda will release a free HD texture pack for the PC version of Fallout 4. Since it is rather demanding on the hardware, Bethesda recommends either a NVIDIA GeForce GTX 1080 or an AMD RX 480 graphics card. On top of that the PlayStation 4 Pro version of the game is also going to receive an update supporting 1440p resolution.
Before you start downloading we recommend you to check whether you have enough free disk space or not, since the texture pack is going to occupy a whopping 58 Gigabyte.
