#132: Task D13 : Dual threaded race engine to improve frame rates -------------------------------------------------------+-------------------- Reporter: pouillot | Owner: pouillot Type: enhancement | Status: new Priority: minor | Milestone: 2.0.0 Component: Race engine | Version: 2.0.0-dev Keywords: multithread core CPU processor frame rate | -------------------------------------------------------+-------------------- Comment(by pouillot): Mandatory for Windows Vista or Seven users : you have to inhibit the "processor affinity mask forcing to 1" in windows/windowsspec.cpp : otherwise SD will only use 1 processor / core, even if you selected multi- threading = on/auto in Option / Simulation. Reminder: this "processor affinity mask forcing to 1" under Windows Vista or Seven was added in order to "avoid jerky rendering" on some configurations ... To let SD use 2 cores / processors (when really there ;-), simply comment out lines 805 and 806 in windows/windowsspec.cpp and see what's happening. -- Ticket URL: <http://sourceforge.net/apps/trac/speed-dreams/ticket/132#comment:3> Speed Dreams <http://sourceforge.net/projects/speed-dreams> An Open Motorsport Simulator forked from Torcs in order to deliver a better user experience through nicer and more consistent car sets, visually improved tracks and enhanced physics realism. |
