We just released the latest update for Bus Simulator 21 including a number of smaller fixes and general game improvements. Here are the patchnotes:

Hotfix #3 (PC):

Graphics

• improved shadow quality on medium settings and performance on higher settings (PC)
  
• fixed transit station materials
  
• improved Crosswalks and Pothole fading
  
• improved far distance imposter quality
  
• depth of field is now forced to 0 to prevent blurry pictures
  

Performance

• improved memory usage
  - tweaked character textures
  - rock imposters where improved
  
• improvements to save game stability while exiting the game (PC)
  

Fixes

• fixed emojis not working
  

Gameplay

• decreased the amount of wheelchair passengers spawning
  

(PS: We are currently working on the other very important and high priority fixes and improvements too, but didn’t want to withhold these ones in the meantime. The next big update incl. numerous high priority fixes is already in preparation but needs more QA testing time, so it will take a bit longer. We will release it as soon as possible.)
