i have geforce 880 gt will it run on what setting will it need to run beam ng driver before i put the video card in my compurte?
Ah... Pretty sure it won't run at all. What are your current computer specs? (Including graphics card)
Theoretically, the 8800GT is faster but it doesn't support DirectX 11, which is needed for versions of BeamNG higher than 0.4.0.6. You'd be better off getting a newer card.
my old 5770 is more powerful than the 5450 but what sort of money do you have and why not get something like a mid range GTX 750Ti those in the UK are around the £100 bracket
Point is: You can run an older version at around 20 FPS if you're lucky, but you won't be getting any updates. If you buy a better GPU, you will be able to play the latest version and get all the updates without a problem.
