This is a small update for 1.0.4, but the new vegetation optimization is in the 1.0.5 beta build, so if you're having issues it would be great if you can let us know how this performs for you!

1.0.4 build

improvements
skip song and previous song buttons changed to comma and period on keyboard
Players can now skip the keybinding overlay after the introduction
headlight shadows are darker now and use less sampling so they're better on performance too.

fixes
Fixed: logging truck liveries had reversed bonus liveries.
Kvannkjosen boats on frozen lake have colliders now
fixed: holzerath haybales at one intersection were a little bouncy
---------------
1.0.5 beta build

features
Offline personal best time functionality

improvements
Optimize Vegetation System to do less combining, faster rendering and deallocation of vegetation. This could range from no noticeable difference to quite a significant boost in FPS and lower jitter.
Lowered the collider of the T22 so the wheels don't clip on harsh jump landings
Sme code optimizations

fixes
Fix bug where 'Barely Keeping it Together' achievement was being awarded even on terminal damage stage completes
Parking Lot achievement no longer awarded before all cars are unlocked
Fix bug where the car would keep some momentum after resetting.
Fix typos in credits
Fixed: when a Xbox One controller disconnects abruptly there was a massive lagspike in the game, we have improved upon that so it happens less likely, but our hands are tied to an issue in XINPUT.
Potential fix for a bug that prevents players from finishing a stage by resetting them to the last waypoint when they cross the finish line
