Hey misifeu, thanks for getting in touch and apologies about the delayed response from our team.
First and foremost, based on the specs you've provided, it looks like you do meet game requirements.
Secondly, may I just double-check whether you're using Windows 10 and also do you have FPS limit set in-game? Also, did you try reducing your graphics settings to lower ones just to see if issue remains?
In the meantime, in order to see if we can resolve this, I would recommend to try completing steps outlined in the following article, and see whether it helps.
Keep us updated!
