Tried the new benchmark demo, with launch options:
-novid -threads 2 -console -nojoy -nouserclip -noff -softparticlesdefaultoffAnd config + comp.cfg
I got 199 fps with host_thread_mode 0 and 201 with host_thread_mode 1.
I turned antialiasing up to mat_antialias 4 and got 211 fps.
This is with a 2500k @4.5ghz and a stock clocked 8GB RX480.
Quick edit: This was in dxlevel 98
