I managed to find a workaround : Switching weather style from
Pure LCS back to Pure Gamma fixed it for me!

@Peter Boese
a good test track for this is Circuit Zolder by reboot team, v1.3
which gave me consistently the 0.5 second freeze every first time I went in the first corner (standing start w 5 opponents, same car, me starting last). (but I have seen that freeze on other tracks as well , so maybe it's even on all tracks , I'm not sure)
So after restarting the race in the same session, it would not do that freeze anymore , you have to exit the session and start a new one to experience the freeze again...
I hope you can use this to find and eliminate the cause of that freeze which is occuring when I'm using LCS (and no longer when switching to Gamma - no other settings changes)
EDIT: Ps: also the jumbo screens look much better w Gamma vs LCS (where hey were too bright to a point where you could hardly see what was playing on them)
