Yes, you must be selective, plate discipline is vital to the process and watching the pitchers release point from out of the hand and recognize what pitch is thrown is essential, (THAT IS THE POINT, Right? Right!) but....
You need a PS4 Pro, plain and simple. The Pro processes faster and when it is used along with a monitor; The Pro supports the 60hz and the Premium HDMI cable also supports 60hz. This is what the Pro was designed for and is to be used with; for Higher Resolution.
(Using a regular PS4 with a monitor and a premium HDMI cable will do little if nothing for you. It may cause even more latency issues.) Especially while playing MLB the Show 20 and the past series. Since MLB the Show is made to support 60hz / frames per second.
The regular PS4 only supports up to 30hz. (meaning 30 frames per second) causing the delay and drop in response time, from controller - to system - to screen.
If your opponent is playing on a PS4 Pro you will know. They are always early on the fastball and other pitches, because the response time is, well..... EARLIER than yours if you are playing on a regular PS4, which stinks for you.
If you are one of the players that are frustrated with timing the fastball and lack the ability to consistently have, Good to Very Early swing timing so you can pull the ball and bash it like your favorite MLB content creator. Good luck, it is not going to happen unless you get yourself the hardware.
It is way to late in the game to go purchase a PS4 Pro. But when the PS5 is out. It will be back to an even playing field. You will get better results being competitive. I promise you that!
People who are not tech savvy would not know this, but after doing some extensive reading. Look what I have found.
I think it is pretty cruddy that there is a disservice here regarding lack of a gaming system capabilities to support new games and the FPS they need to play efficiently. But it is what it is.
And for MLB the Show... Hey if I have an advantage and I was exploiting someone's weaknesses because they swing at everything and missing mass majority of Fastballs. Who fault is it; NOBODY'S....
Honestly it is not all You.... It is definitely your system. Also plate discipline is a factor. But it really stinks swinging at balls you know are coming down the pipe and you can't seem to make that contact you know you should. Foul-Tip-Oppo all day long.
Good Luck.... New generation console is almost among us.
