Hard-pressed to say so. Looks like you don't have any dedicated graphics and a 2core/4thread processor.

What's that mean in idiot terms?

Do I need a new gaming PC or would I be able to take it to a computer store and add the parts for less than a new PC would cost

you don't have a graphics card basically.

your proc is also weak.

I would buy a new pc.

It's a laptop. You can just add a GPU to it. Well you might with an external GPU over thunderbolt, but that really don't work that well.
You need a new machine with a dedicated GPU. even a low end cheap "gaming" laptop with GTX 1660 would work fine.

Sell your 2003 account and use the profits for new computer

Who, me?

Looks like poop Beeetle need new rig

Sad thing is that laptop can't be more than 24 months old. I guess design and portability was more important?

I bet you could find a cloud computing app to run the beta through, but dont worry you aint missing shit!
