Re: Torcs 1.3.5, compiling for more then 1 core, running without focus

Hi Schnuck

Thank you for the report:-)

Currently it runs on one single core apart from the sound processing 
with OpenAL, this runs in another thread. But with "only" 15 cars the 
graphics card is the limiting factor usually, switching off the rear 
mirror, reducing the visibility and setting wheel rendering to simple 
might help most. Alternatively you could get/use low poly car models 
(e.g. from ancient TORCS versions).

I guess the "hidden window" thing was desired to avoid noise/power 
consumption. Are you aware that you can run TORCS in command line mode 
without GUI whatsoever (see FAQ, researchers section)?

You could make the glutIdleFunc point to "reDisplay" in racegl.cpp 
during the race, this would then keep the processing running (when the 
window is hidden the postRedisplay just marks the window with "requires 
redraw", so no event is generated and TORCS "stalls"). To find the 
proper place to add this just find the place where glutDisplayFunc is 
set for entering and exiting the race, so adding just 2 lines of code 
might do the trick.

Everybody else: Is it a common demand to change this behaviour?

Hope this helps

Bernhard
