GTA IV cannot detect dedicated Nvidia GeForce 840m

Hi, i recently upgraded from Windows 8 to Windows 8.1 due to the horrible DPI scaling and blurry screen that i was having on my new laptop. Now that issue solved, i am unable to run GTA IV on the dedicated graphic card. It only recognizes the Intel HD 44000 and that's it, runs in 800x600 with minimal settings. I've been trying everything for two days, including forcing it to launch with Nvidia, to no avail. Any help? 🙁

UPDATE: I cannot believe that the solution was (that i've found at this very second) was to set the Games for Windows Live file (GFWlive.exe) in compatibility mode with Windows 7. This game is such a mess.

Did you try your laptop, connect to power source and launch the game?

I only had to change the compatibility for Windows Live as written above, quite unbelieavable. Yes, the PC was plugged-in all the time. Hopefully someone will find this useful.
