System Requirements

Space Engineers is currently in alpha and these are only the preliminary specifications. Hardware requirements could increase or decrease depending on future iterations. As of now, here are the current specs for Space Engineers:

Minimum Requirements	Recommended Requirements
OS: Microsoft Windows XP (latest SP) Processor: Intel Core2 Duo 2.0 GHz (or AMD equivalent) Memory: 2 GB RAM Graphics: NVIDIA GeForce 8800GT / ATI Radeon HD 3870 / Intel HD Graphics 4000 DirectX: 9.0c Hard Drive: 2 GB free HDD space Audio: DirectX® compatible on-board	OS: Microsoft Windows 7 (latest SP) Processor: Intel Quad Core i5 @ 2.5 GHz (or AMD equivalent) Memory: 3 GB RAM Graphics: NVIDIA GeForce GTX 460/AMD Radeon HD 7800 series * DirectX: 9.0c Hard Drive: 5 GB free HDD space Audio: DirectX® compatible on-board

Steam account and internet connection to install the game. No internet connection required to play the game.

Recommendation from a user concerning choice of PC components [1.069] / Feb 2015:
Space Engineers is very CPU heavy. A quadcore with a high frequency is currently performing better than a hexacore with a lower CPU frequency.

In the users' case:

Old system	New system
i7-2700 @ 3.5 GHz GTX 580 8GB RAM SSD Windows 7 Home Premium	i7-5820 @ 3.3 GHz GTX 980 32GB RAM SSD Windows 7 Professional

The FPS and UPS are slightly better with the old system ! The only "noticeable" advantage of the GTX 980 over the GTX 580 is the render capacity. At 6.5 million triangles the GTX 580 can't update all objects in a frame anymore frequently showing the interior of objects whereas the GTX 980 still manages to display all triangles in a frame.

So if you already have a high-performance quadcore and a good graphics card there's not much benefit from replacing it with a "better" system.
