A videocard is hardware, so you will need to buy and install new hardware to upgrade your videocard. Contact the store you bought your computer from, they will be able to give you the proper advice. Since you have a Mobile Intel though, you’re probably using a laptop… so there is probably no way to upgrade the videocard
Unfortunately Intel videocards are nearly useless for any game that uses a modern engine, but many laptop manufacturers still use them since they’re cheap.
HOWEVER, before you look into buying new hardware, first test if Kudos can’t be made to run anyway.
If you look in the data folder inside the Kudos folder there is a file called ‘config.muf’. It’s just a text file you can open with notepad.
If you add a new line at the bottom of it that says:
IgnoreIntel = 1
And then save it and re run the game, it may work ok.
Also make sure your version of Kudos 2 is 1.05. If it is not, download the patches: if your version is 1.04 you need only 1.05, if it is 1.03 you need first 1.04 and then 1.05, etc…
