Ark survival evolved on a console?

My girlfriend and I have been playing Ark offline in split screen mode for a while, unfortunately annoying laggs, the distance limitation, etc.

I just had the following ideas to get us the fun of the game, but I'm not sure if that's as possible as I imagine it to be.

1. Rent an online server and play on this split screen? Would relieve the console and remove the distance restriction, but find no clear source whether this is possible.

2. Screw the graphics down so that the standard ps4 in the offline split screen is not that bad with every action you do.

Vll know someone advice, thanks in advance.

For the server you need PS Plus and I don't know whether the splitscreen is on a server but it can fix the laggs

Spliscreen does not go online on a server, I made an extra 2nd Ps plus account, thought is different if you rent a server yourself but kp, so the question

How to screw down the graphics?
