Low FPS since update

Hey community!

In the earlier versions (last time I played was most likely more than a month ago) I had decent FPS and good FPS in gridmap with normal settings in BeamNG. No lag even in high speed situations. Now that BeamNG seems to be updated, I get lag even in gridmap with the LOWEST settings. When not driving the FPS is about 40fps. I have tried to mess around with the settings and Vsync and such. All filters and post processing stuff is turned off. My gear:

PC, Windows 7
8GB DDR3 RAM
Nvidia GeForce GTX 550 Ti
AMD FX-4300 quadcore 3.8GHz

My knowledge says it should run OK, but it doesn't. Anyone with similar issues (or solutions) since the update?

 

Having the same issue and no one can help.

 

Very, very, very annoying problem.

There's the link and log also attached. This was with some settings including texture quality set into lowest, some low. I'd figure it should be capable for more than average 25fps while staying still with that car in those settings as described. And as said, it used to work much better when I last played, it did even back when I had only 4gb of RAM available.

E: Also tons of these in the logs file which caught my attention.

This was with mostly Normal settings (Some turned to lowest, like post processing, shaders, AA off), no Vsync. Afterwards tried to drive in the pure grid and no lag, which wasn't a surprise as it has always worked best because of it being well, purely grid.
