Performance optimisations[edit]

We focussed on performance this month, and achieved a speed boost of at least 50%. This work is ongoing.

  • Now defaulting to the VS2015 build, with the old VS2008 build still available for Safe mode (Prison Architect Safe Mode.exe). This gives a good speed improvement over the VS2008 version.
  • Asynchronous job search system. Instead of synchronously looking for a job, workers, guards, prisoners, doctors now place a request for a new job in a queue. This queue is processed during render phase of the game loop so shouldn't take up any time during the main game loop.
  • Speed up rendering of the Feed Prisoners Objective. This was particularly slow when there were a lot of hungry prisoners.
  • Rebuild the indoor/outdoor shadow mask only when a cell changes its material or indoor/outdoor status.

Thermodynamics (continued)[edit]

These operate on a seperate layer to the existing pipes, and can be overlaid without conflict.
Requires a large pipe connection of cold water, and a direct electrical connection.
You can run hot water pipes from this boiler in any direction.
Nb. Water will lose heat the further it gets from the boiler.
  • All radiators now require a hot water connection to function
  • Showers can take cold water or hot water.
When supplied with hot water, showers will also reduce a prisoner's Warmth need
When supplied only with cold water will apply a Frigid effect, which acts as a kind of short-term surpression while also spiking their Warmth and comfort needs.

3D mode has been discovered[edit]

This update we have improved 3D Mode with new shapes, new shaders operating on all objects, and better wall geometry. 3D mode remains very experimental.

  • Known bug: The mouse position is wrong when using graphics/Supersampling.
  • Known bug: Long pauses caused by geometry changing, eg wall construction/demolition

BUG FIXES[edit]

  • Thermodynamic map to use 16 bit number type to represent the temperature instead of 8 bit. This fixes a bug with fire showing negative temperatures.
  • 0010610: [Graphics] entire screen is black and white boxes
