New for tech4x:
|
|
|
|
|
|
|
|
Unlike previous SMP work, the actual GPU command drawing is done in the main thread, which avoids the
|
|
|
|
OpenGL problems with needing windows to be created by the same thread that creates the context, as well
|
|
|
|
as the issues with passing context ownership back and forth on the 360.
|
|
|
|
|
|
|
|
The game tic and the generation of the draw command list is now run in a separate thread, and overlapped
|
|
|
|
with the interpretation of the previous draw command list.
|
|
|
|
|
|
|
|
While the game tic should be nicely contained, the draw command generation winds through the user interface
|
|
|
|
code, and is potentially hazardous. For now, the overlap will be restricted to the renderer back end,
|
|
|
|
which should also be nicely contained.
