Sorry, but even if you turn it off, the signal still starts from the video card, did you mean to disconnect it? then in the nvidia driver setting it is on the simulator it is set to full hd , my combination of cpu and video card has a big bottleneck using a full hd setting , it would improve with a 4k .
I mean that if I use the Reverb also the video card signal goes to the monitor even if this is off and also the graphics settings on the nvidia panel and the sim set to full hd do not affect?
