Is this a joke? A HD4200 - and all other x2xx cards I'm aware of - are office cards. The newer iterations have added boosters for a couple of video standards, making them a good choice for a low cost HTPC which is still fast enough to get the job done.
So you shouldn't seriously expect to be able to play a demanding game on a PC with such a graphics card.
The later CPs for G3 fix many other bugs and scripting issues. There was also one release which fixed technical issues, but that's an exception because generally speaking a team of enthusiasts from the community can't dig deep enough for this.
