Trouble with terrain maps?

What sort of laptop are you using?

Full name in this case which means Brand and then series and then particular number/type of computer in that series. You should be able to find a sticker on the back of the computer telling you what exactly it is.

I'm not sure if, say, this was the exact things you may have mentioned, but I'm still a tad bit new to this stuff.
I ran a few weird things to look at it, since the sticker doesn't state the computer name and such.

System Manufacturer: Gateway
Computer Name: USER-FFD4564B31
Operating System: Microsoft Windows XP Home Edition (5.1, Build 2600)
System Model: M275
BIOS: Rev 1.0
Processor: Intel(R) Pentium(R) M processor 1600MHz

If this isn't it, I could always take off a few parts to see if the company hid the sticker somewhere, or run a few other things for help.

I'm very safe to say that it's due to the age of the laptop, from what I can find that computer is from around 2003 which is most likely why it cannot draw the textures properly, and I do not think there's any drivers that would sort this out I'm afraid.
