Below you can find the recommended specs to play the game :
There was an interview with CD Projekt RED Managing Director Adam Badowski, the interview was in Polish, and a fan translation was presented. The main piece of info that everybody was looking at, is that the recommended specs will allow you to play The Witcher 3 at 30 FPS.
The hot question and answer:
PC recommended specs will be able to run the game on 30 or 60 frames per second?
I think, we’ll stick with 30 FPS. We’re not going to stop working on performance until the very end, it’s crucial matter to us, there are different PCs with different specs. Programmers insisted on avoiding tricking the players by lowering predicted specs. As I mentioned before, It can only get better.
A lot of people thought it will be locked on 30 FPS on PC which is a huge let down for alot of people, but that doesn’t mean that it won’t go above 30 fps, it will go above 30 FPS when having a strong pc, stronger specs than the recommended specs, For Example your on the recommended specs so the game will run on stable 30 Fps and will go higher depending on the clock speed you have or if you have a stronger graphics card.
