mastercomsmat_queue_mode has to do with the graphics card as much as it as to do with the CPU, don't use a low resolution for it.
What do you think is the best way to tell if i should be using mat_queue_mode 2 or -1 ?
at first glance it looks like sourcebench.csv has loads of stuff, but the extra info is just dxlevel, launch options and telling if a few settings are on or off
