i have a dualscreen setup, running different resolutions on each display. when i set both renderer to fullscreen (at the native desktop resolution) the framerate drops dramatically.
one observation, if just one renderer is set to fullscreen and the other one is windowed but resized to fill the whole screen, then everything is fine…full framerate.
its just the state of both displays set to fullscreen.
nvidia graphics card setting is set to multidisplay mode.
has anyone came across a similar behaviour ?
