nVIDIA stopped producing complete GPU cores for laptops with Intel CPUs. The Optimus is only the "back half" of what a desktop Geforce GPU core contains. The Intel IGP cannot be disabled, because without a front end, the Optrimus relies on the Intel chip to do everything. If I was gifted a laptop with an Optimus, I'd swap it for another machine to avoid the nvVIDA cripple.
I thank you for trying to help me but it took me a lot of time to be able to purchase that laptop. BF4 is the only game that does not work so I do not think the laptop is at fault here. BF3 works perfectly at 900 p on high/ ultra on multiplayer. I would have tried all the other suggestions, that going to device manager and disabling integrated gpu might work. But the sad thing is I am out of game time. I however did discover a soluttion though and it worked.
For the solution to work,
I had to go in origin and run the default bf4 in 64bit version. Then oh well I would get 4-5 fps and with all that pain I would change the graphic settings to a more suitable thing for my laptop about med/high. Then i quit the game and made origin open the 32 bit version of the game and for some reason that worked. I played it for a few days like that but then it started crashing to desktop again. So i do not feel very confident buying the game just to find out it does not work. 20 dollars is a lot of money where I live.
Would it be possible somehow to get an etension on my game time? a couple of days just to check things would be good. If things work out I assure you I will purchase the game.
