It looks like the PC system requirements for Resident Evil 7 were released today. Since the game is a little ways away, these are subject to change but this should give you a good idea of what to expect.
MINIMUM
OS: WINDOWS 7,8,8.1,10 64-BIT
Processor: Intel Core i5-4460, 2.70GHz or AMD FX-6300 or better
Memory: 8 GB RAM
Graphics: NVIDIA GeForce GTX 760 or AMD Radeon R7 260x
DirectX: Version 11
Additional Notes: 1080P CPU/GPU at 30FPS Players will have to either lower texture or set streaming textures to OFF in order to optimize performance. *Internet connection required for game activation. The game is still undergoing development, so all PC requirements are subject to change.

RECOMMENDED
OS: WINDOWS 7,8,8.1,10 64-BIT
Processor: Intel Core i7 3770 3.4GHz or AMD or better
Memory: 8 GB RAM
Graphics: NVIDIA GeForce GTX 960 or AMD Radeon R9 280X or better
DirectX: Version 11
Additional Notes: "1080P CPU/GPU at 60FPS *Internet connection required for game activation. The game is still undergoing development, so all PC requirements are subject to change."

If confused by the "additional notes" section, it seems to me like the "minimum" specs will get you 30FPS at 1080p. Some users may need to make additional adjustments to maintain performance at those specs. The recommended specs sound like they will get you 60FPS at 1080p.
