[SOLVED] Can't run the game with nvidia optimus on windows 10

[BlackDisk]

Hi all

I just upgraded to windows 10 today and I updated all the drivers
but I have problem with this game only.

I have laptop with two graphic cards.
One is intel 3000 and the other one is nvidia gt-525m.

So, If run the the game with nvidia for first time after windows start it will run fine
but I can't make it run again until I restart my laptop:



the good thing that I can run the game all the time with intel graphic card but I am suffering with low fps on it.
and I have desktop that have integrated nvidia card and the game run fine on it.

So, I think the problem is with nvidia optimus.

I tried to reinstall the game and update openal but the problem still there.

Does anyone have this problem?
Is there any solution for it?
