更新说明：

Update v110:

If you experience low performance give disabled shadows a try, with this patch it still looks great but will give a 50% fps increase.

Fixed

Optimized shadow casting lights
Fixed sun light leaking when shadows were disabled (Game now looks great even without shadows!)
Updated to 4.9.2 engine base
Fixed some objects being culled before they were off screen
Fixed all known physics bugs
Fixed the player being thrown out of the elevator into space
Fixed shadow settings being reset when getting a checkpoint
Default settings on first run are now much better optimized with a 50% performance increase compared to the original defaults.

Added

Opened up two rooms on level seven
Airlock on level five
Torch that does not break after 15 seconds
