Graphic probem with some games - Win 7

All of Aldorlea games I tried used to run fine on my old notebook/netbook Eee PC 901 with Win XP.
Now I have Eee PC 1215N, Win 7 Home Premium 32 Bit, DirectX 11, two graphic cards, primary Intel and NVidia ION. No matter under which one I run the game, some of them (Arevan, Vastar for example) are really choppy and slow. Sylia is ok though...
Anyone know how to solve this problem? Drivers doesn´t need actualization, I tried to change compatibility, I tried to set lower hw acceleration, but in normal mode system won´t let me get there and in safe mode I can get there, but it won´t save changes...
Can you help?
