Ok, it seems I have found the solution...
It has, suprisingly, nothing to do with the graphic card... I am running the game on my HD graphics 3000 without any lag...
Ok so I have uninstalled the whole game again...
I have also deleted ALL saves or data arround masseffect... whole ME2 saves file has to GO.
If you wanna keep your saves of some character(s) ur playing you need to copy and paste the folder NAME_Class_lvl_number to somwhere else...
For example TryGG_Infiltrator_24_252331
After you have deleted everything, go and instal the game again.
Once you are done, DONT EVEN think about running the config, it fcked everything up for me...
Now go into your ME2 folder, binaries and run ME2game
It should work...
Ok if it does, turn off the game and put the saves of your characters into documents, BioWare, MassEffect2 and create folder ''Save'' and put it into it.
Now you should be able to run the game from origin... if cloud asks, tell it to use your current saves in PC.
Again, dont ever run config, it made the game not to start for me with the stupid error announce before it Every Damn Time... and I have tried it like 6x.
I hope it helped.
My thanks to Fred for even trying to help me.
