NVidia Optimus (GTX00M) Cannot Run in Fullscreen Mode

Ok, so after researching the issue and working with several laptops/pc's (i have access to several workstations) I can suggest several solutions. 

*Note - not all of them will work, but for some of you it will. It didnt work for my laptop, for instance. But I could make it one of old pc.

We seem to have problem with both IntelHD graphics and Nvidia. Majority of laptops which have Geforce M series Graphic cards do also have Intel graphics. So basically, when we launch the application, the display settings go through IntelHD, not via Nvidia, and Nvidia acts like renderer. If you dont believe me - go check your DxDIag and see what is in your Display tab. Simply using nvidia control panel won't work, bcuz it wont change default display device (and it is InteHD). The compability of this two usually dont bring much problems, but have some issues when running applications with DX11(such as DAI)

Example - you cant change WoW/DA2 gamma in DX11 because of this problem. Same thing seem to happen with DAI(and hell thanks optimization {*no optimization} issues are even worse than gamma).

- Try going to your manugacturer's website(Asus,Acer. etc.) and update IntelHD drivers. Or search for the latest driver on Intel website(latest drivers didnt even want to intall on my laptop though)

- If you are able to, in BIOS set NVIDIA device as a default display renderer(very few laptops have this settings in BIOS, but maybe you have).

For the same reason people who have teamviewer have this problem - game processes through several display devices/options, whch cause the conflict. For the damn same reason fullscreen works if you launch with IntelHD - Since you lauch it with single display adapter.

Hope this helped all who are here, or atleast gave you idea to find a possible global solution
