The specs and requirements are expectedly higher than those of the original game but not too demanding. Alan Wake Remastered won’t, for example, offer raytracing, so you won’t need a GPU that can handle that. 

Alan Wake Remastered Minimum Specs, Requirements

CPU: i5-3340 or equivalent GPU: Nvidia GeForce GTX 960 or AMD equivalent w/ 2GB VRAM RAM: 8GB HDD/SSD: ~36GB OS: Win 10 64-bit

CPU: i7-3770 or equivalent GPU: GeForce GTX 1060 or AMD equivalent w/ 4GB VRAM RAM: 16GB HDD/SSD: ~36GB OS: Win 10 64-bit

The PC version will only support 64-bit operating systems and those running DirectX 12. It will have DLSS, ultra-wide monitor support with full screen, windowed, and borderless options, and draw and render distance sliders. 

There will also be options for ambient occlusion, motion blur, volumetric lighting, terrain quality, FOV, film grain, HUD (enable/disable), shadow quality, and anisotropic filtering.
