Three years old Intel should be good enough to play TS2. It looks like shader issues so I wonder if you can set Intel (in it's panel) to clear that up. And sorry, I forgot (without rereading thread) if you have updated your driver. You will have to run Graphic Rule Maker again if you do ever update any drivers.
ETA: By the way, what is your Intel card/chip? So someone can look up if it's in the supported GRM list of cards it knows about or if you will have to do more than just run the Grapic RM. (You may have to change the CS config files too).
