We just rolled out Studio Runtime v2.0.0 with a leveled-up physics engine — delivering faster performance, more reliable gameplay, and new tools for greater control. 
See the Upgrade Guide here. 
for more details.
Here’s what’s new:
Kinematic bodies — scripted motion that still collides and reacts
High precision collision detection — collisions always register, even at high speed
Improved physics performance
New projects automatically run on the latest runtime. Existing projects can be updated at your own pace, so you can bring improvements into production when it makes sense for your team.
