,My experience arrived at by trial and error when it first happened a few months ago. I am NOT an expert and have 3070ti. I have a few things in community, just some liveries and a couple of airports. I fly A320 fbw and, apart from cleaning the pc, which is 15 months old, I've not done anything. Mostly fly high to ultra and, with latest update, at about 90 fps, before was about 60. So this is what caused the message and how I now avoid it. I use 55" LG uhd tv and a 27" monitor just for instruments which I drag down from tv. If I use afterburner with DX 12 beta message appears, freeze and ctd., (using DX 11 does not cause problem). For me it is as simple as that. I prefer the DX 12 as it seems better so I do not use afterburner. If I do need to measure or monitor and want afterburner, I avoid the monitor. Simple as that. Nvidia always updated but I do not think makes a difference. This is just me but maybe might help someone. Willing to answer questions but only if simple!
