My dedicated nVidia GPU can not be used as GPU and it uses integrated GPU

I have laptop MSI GE60 (760M+i7 4700MQ) and other NEWER games are running fine, but SCP: CB just lagging and I have figured out that it uses INTEGRATED GPU, not the more powerful one (dedicated). So I went to nVidia control panel, i changed everything to be on that 760M GPU and still IT IS NOT WORKING. I changed anything I could, so please, tell me what to do about it and how to fix it, because I was enjoying SCP: CB so far :).
