Yeah the loading times were getting unsually longer than normal on my PS4 slim. I was still using it even when I had a PS5 but eventually just moved everything over to PS5 cause I was tired of how sluggish the UI was and the loading times. While better, still not as good as my PC.
had similar thoughts when I gave my PS4 to my brother 2 years ago, haven't missed it a day since, unless I feel like playing some Virtua Fighter then I realize that shit still isn't on PC lol
