How to upgrade my graphic card?

Computer nib here.

So, I recently got a windows 7 64 bits comp, and I think the graphic card is outdated. I lagg way too much when playing some 3d MMO's (Vindictus and Dragon Nest mostly). I spent a lot of time on google but nothing seems to work.

My card: NVIDIA GeForce 6150SE nForce 436

Halp please!

I don't want to install a new graphic card, I only want to upgrade mine through internet.

Tried this, doesn't work.

Then it obviously isn't your graphic driver.

There's a setting in Vindictus that allows you to change what version of DirectX is runs on. The default is DirectX 10 I believe, so change it to DirectX 9. While your at it, you might as well change all the options to their lowest setting. For Dragon Nest, there's a quality option in the Game Settings menu. Change that from High to Low.

If this doesn't work, one of two things needs to happen, you need to overclock (which isn't possible because you have an integrated GPU and most likely a distributor-locked CPU) or buy new parts.

If none of this works... Buy a new graphics card theres no way around it. You can only do so much with a graphics card before you have to change it.

This is the best bet you got.

I really didn't notice that much difference when I got it, though, so I switched back.

Error launching the installer.

I should just give up.

Maybe your computer just sucks, OP.
