Surface pro3 lag

I really need help/support because my Surface pro3 is very laggy (only getting around 4-6 fps) I need setting reccomendations plz. The lag is very annoying.
Have a nice day!

 

Your CPU and GPU are not powerful enough. The i5 4300U and HD4400 (assuming it's the i5) are not suitable for gaming, especially not on the Surface's 2160x1440 resolution.

 

Is there anything you would recommend to change it to?

 

The lowest you can set it while it's still playable. The Surface Pro 3 was never meant for gaming.

 

Maybe trying to lower your resolution to 1366x768 (Don't know if it's playable then) would give you some more FPS, other than that there is nothing I think.

Integrated graphics are not recommended, and your processor is an dual core U-series, meant to be very power-efficient rather than powerful.

 

Set everything to low. All you can do. GPU is extremely underpowered for beamng, that said, I play on lower on my laptop.
