MSI Afterburner as OSD keys to choose make sure that and gpu temps, usage are selected to show it as well on rivatuner must have osd set on either the low or medium setting for application detection level. Then in game hitting the key you set or not it should show up. BF5 is gpu intensive, so I'd also recommend setting a decent fan curve to keep the card cool enough to pull as much mhz as you have with what you have OC settings to.
If your fan aren't turning on that's a whole other issue with the card itself or something is nvidia control panel. There settings in there too to boost performance. Just FYI I use texture filtering quality set to high performance. Don't worry it effects no game graphics.
I just played RE3 DEMO with everything max on my 1070 ti. Well around 100 FPS. However RE engine one of a kind. Like seeing everything sweat pore on them is just insane and the lighting is glorious.
