Ironically Trine 2 provides a better performance than the first one. If you haven't played it, try it!

Coop multiplayer puzzler with some interesting gameplay aspects. Even alone worth it's price but with a second player much better!

Mafia II is a thrilling action game with credible characters in a open world like grand theft auto. Runs smoothly and makes fun!

Great puzzles and old school tomb raider gameplay. Not that visually stunning as the newest one but a look worth!

Most of you won't believe it but: Even on medium settings Tomb Raider will run smoothly on your HD4000. Really enjoyable even on laptops!

Actually the best looking HD4000 game. It's amazingly optimized for HD4000s. Great shooter at all!

Ever wanted to be a thief with teleportation? Try Dishonored! It's a great stealthgame with an interesting story!

Sci-Fi with acceptable graphics on lowest settings (and good fps) and overwhelming story! A must have if you like shooter and RPGs!

On lowest settings it doesn't look like it's about 10 years old and runs pretty good on our (beloved) HD4000!
