I noticed that Rocket League would always launch into 1280x720 or some weird resolution, along with it being incredibly hard to run considering I have had no issues before. My screen would just flicker constantly, while it isnt too bad, its definitely noticeable. It would struggle to run, reaching staggering lows of 5FPS. Furthermore, it would sometimes crash when loading stuff. Sometimes I had have to reboot my computer in order to terminate the stuck process.
