ok guys, so i downloaded the new nvidia drivers 258.96 and installed 3 games;

Counterstrike Source
Live For Speed
Mirrors Edge

CSS - when i play multiplayer (OMG server with max 36 people) my fps starts off high, around 100 fps, after about 15-20 mins of playing my fps falls to like 17 fps where it becomes very choppy

LFS - no problems with this game watsoever

Mirrors edge - Majority of the fps is good, like around 62 but then there are times when the fps sudden drops to 11 fps and its very hard to play.

All games i have tried dedicating the 335m as gpu and also i tried the auto select. I also turn vsync off on all games.

Check my CPU and GPU temps etc and dont notice anything out of the ordinary.

I have also recovered the system and still have the same effects. its almost as if im running on 335m and then suddenly it switches to the intel hd gpu and the fps falls. I dont know if this is a hardware issue or a software issue right now.

Fairly frustrated cause i bought this laptop to work and have a bit of fun, didnt think it would be so much hassle.

Wondering if anyone has any ideas on what i could do.

Thanks.
