Could anyone with SLI 970s confirm if you can use Dynamic Super Resolution by going into the NVIDIA control panel and selecting "DSR factors" in the Manage 3D settings section please?
Heard a few reports of DSR not working for some SLI users and that would be a real shame if I wanted to get another 970.
DSR is single GPU only at the moment according to an Nvidia mod.
