Dissapointed with portal, guidance needed

Edit- disappointed I spelt disappointed wrong. Hey like many others I picked up a portal after reading through this Reddit. I’ve had a steam deck and used chiaki which was really good. I’ve not got a portal and it’s truly awful. The quality looks terrible in comparison. There isn’t any way to change the bit rate?. Those of you saying it looks and plays great?. I honestly can’t see how, what are you comparing it to?
