If your computer is "ancient" as you said......a new video card might not even fit on your motherboard....seeing as hardware is constantly being improved and changing.
I tried to upgrade a 4 year old computer with new RAM....didn't fit. Bought a new video card....didn't fit either.....
So I bought a new motherboard that would be compatible with my new RAM and Video card. The motherboard didn't fit inside the case.
I ended up replacing everything, and building a brand new computer from scratch. I spent around 500 dollars...and it runs Blockland brilliantly with all the graphics maxed.
So...What I am trying to say is....you may have to buy a whole new computer. Bug your dad about the old one......search for a used on craigslist....look in the local newspaper.....I'm sure you can find a decent computer for next to nothing that is better than yours.
Okay, really, for the last time, you loopy people (

) I CANT AFFORD IT. A new video card WOULD fit, I checked a while back. Even if I did buy one, it'd be entirely pointless. With my luck of money, I'd blow it all on the video card and then have no money left for Blockland. So, in turn, its pointless.
Um my old video card supported blockland alot better than it did roblox...
What do you have?
