I appreciate that LFS devs have the frontality to come to us and say "the release will be postponed because of A, B and C", not leaving us in the dark.
Patch Y is a great patch. The game is evolving (lots of new tweaks now!), and I don't understand what's all the fuss about this patch. Who drove well before, can drive well now with the patch Y.
I've driven a bit in the new patch Y, and I like what I've seen/felt. It's moving towards more realism, not forgeting the pleasure of a videogame, which is very good.
Try one thing: reset your braking points to earlier times, corner with just a maximum 1/4 of wheel turn, aim for the apex and use all the width of the track. Keep doing that as you brake later and later, until you reach the limit.
