Replay lag intermittently with multiple cars

basically the title, it never did this before, i don't know if this happened after the last hotfix but now the replay after every second it lags for less than half a second making the replay unwatchable, this happens when there are more cars in the scene.
It not a hw issue since i have a 5950x and a 3090 with supporting hw and while recordinmg the replay the game is perfectly smooth, besides this is the first time i see this with the same hw.
anyone having this issue?
anyone found a solution?
thank you

 

Hi, i have same issue. Did you fix it somehow?

 

Even in the latest verion of beamng 29.1 I still have the same problem even tho now I have a 4090 and it's not even maxed out, could this be a game's limitation?
