I have a GTX 750ti and an RTX 2070 super. Unfortunately my monitor doesn't have a DisplayPort, so I bought an adapter first, but it doesn't transmit 144hz. I then installed both graphics cards and connected the monitor to the 750ti. In Rainbow 6 Siege my 2070super is used automatically. But in Fortnite my 750ti is there a way to change that?
I would not be aware that something like that is possible. How did you do that?
No idea somehow turned black when starting the 144hz could still use the other graphics card that is not on the monitor
Actually you can't combine these two graphics cards. Remove the 750ti and use the adapter until you have a new monitor.
