Hi,I’m using Razer Cortex as a default option for my PC. However, with the latest Starfield release I found that Cortex is detrimental to entire game. With Cortex up and running the game performance is <30FPS and more importantly most of the UI elements are not actually drawn.The moment I quit Cortex and restart the game it runs smoothly with 60+ FPS.Let me know if there are any logs or anything to share to investigate?

Hey there!Thank you for sharing your issue with us here. My name is Michelle, and I’m part of the Razer Cortex technical support team. I am happy to help you out.We assume this issue was caused by the FPS overlay. Please turn off the “CUSTOM DISPLAY” in Razer Cortex > LAUNCHER > IN-GAME. Then, play this game to see whether your game performance is good.We sincerely apologize for the inconvenience this issue has caused you. We will disable the feature when the game is officially relesed.We look forward to your reply soon. Thank you for being petient.Michelle
