I have the latest driver available. So there's nothing i can do at the moment, but to wait for the bugfix or a new set of drivers,
if the driver glitch is the case.
If anyone else is experiencing something similiar i'd like to hear about it, just to confirm that it's nothing that is failing in my system...

Found the problem! Or sort of... When i change the resolution down, and back to 1920x1080 @ 59Hz the game starts to work as normal. But i have to do it every time i start the game.

didn't help at all. i have tried almost everythin i can think of.

Forgot to mention that the framerate jump is constant, it is 100 for about 2 or 3 seconds and drops to about 50 or under for about half a second, and then back to 100 for 2 or 3 and again and again... So the game is now totally unplayable.

Dirt rally and assetto corsa works fine, LFS is only game that has those kind of glitches. I have 16GB of RAM so i dont think that's the case...
Only program (other than windows's own programs) i have on in the backround is AXTU to manage my fans... I belive this problem came with the new update of LFS...

My LFS worked fine but after i installed new update 0.6J it went all wrong.
Framerate jumps from 100 to about 50.
It's unbearable stuttering to play.
I Have I5 2500k and radeon hd 7870 so the problem can't be my hardware.
Os is Windows 10 but it worked fine with 0.6H so i don't it's that either.
Please help!!
