@Lrom94 - I'm afraid we're not aware of any active issues regarding framerate problems on Stadia. I would recommend that you check and ensure your connection is optimal to run the game. if you continue to experience problems, I would recommend that you reach out to Google support for further assistance.
@Adrian-11 - I appreciate the potential solution here, I understand that these steps have also assisted several users experiencing the crashing issues aswell. That said, it is important to note that the steps shared by my colleague are also useful. Every system and experience is unique, those steps above have been known to help rule out many of the common causes for technical-related issues.
