I'm having problems with my laptop (ASUS k501U I7 6500U GeForce gtx 960m windows 10) when I'm using the hraphics card it's super slow but when we I use integrated graphics from my processor it runs really well I dont know why. Anyone have ideas on what to do to fix this?
I'm not much into laptops, but on mine (AMD) you can set the 'Power-Plan' of the Dedicated Graphics. You need to check from the Nvidia Control Panel if there is such option. Also, you checked with your charger plugged in?
Most probably you are actually using the Nvidia although settings shows the other way round. I had a similar problem with other game (Hitman) and the issue was that the game was using the Nvidia card although the settings said Intel HD and viceversa. Check the Nvidia agent while in game (when is running well) and you will probably see that BeamNG is using dedicated graphics.
