To all those mappers out there, feeling the pain of those long compile times even on good PCs. It was never your fault! Blame Volvo. ):

Turns out a intersection tracker in the raytracing code for VRAD was decreasing performance the more threads you had due to poor multi-threading programming knowledge??? Jokes this was obviously a mistake but still the performance hit is abysmal and this bug was in VRAD for years without anyone knowing until now.

Great thanks to the guy(ryandmaclean) who found isolated this bug
