Easy way to decrease lag?

I keep getting lag spikes , I tried putting the power plug in, restarting the game and still nothing, I have a geforce gtx 760, but it still is slow?
Any tips?

 

Heres whats probably happening.
Maybe you Have to many mods
OR the fact is you probably wanna clear youre cache

 

How much RAM?
What CPU?

 

8 gigs of ram, i5-4210m

 

First, if you haven't already, disable dynamic reflections. Then, disable SSAO and turn the shader and lighting quality down to medium or lower. Beyond that there is reducing grass density, however, that may not change anything depending on the map

 

Interesting, I have the same specs and I can run 2 cars with dynamic reflections and all that at 30 fps. Have you tried clearing cache, safe mode, or a clean reinstall?

 

I had to get a new harddrive turns out something was lagging my pc.
Its all fine now

I said that because I was lagging before I got the new drive, But i just re-installed the game and it runs smooth

 

Step 1: Close every programm running in the background. Especially Chrome, Steam, Discord
Step 2: Open Taskmanager and set game priority to high

 

Turn off shadows and you can run BeamNG with very low spec CPU, number of lights and objects is related to how heavy shadows are on CPU, if you have GPU power and get weird lag spikes, shadows are very likely reason.

Addition to that, keep SSAO and dynamic reflection off and almost anything can run normal details. Going lower than normal detail level is not making too much of improvement at least in my system.

Press F11, on right type level info to box, find visual distance and lower it to something like 800-2200 if you want to keep shadows on.
