Definately not lag. I have a Ubiquiti UDM Pro with comcast business 3Gb symmetrical fiber connection, and a Mellanox ConnectX-4 Lx Ethernet Adapter nic direct to my 10Gb switch. As you can see, it's a 1ms ping. Also I have never once seen the in game performance icons pop up.

OK On to new topics. My friend suggested underclocking my RTX 3090 and I think it worked. I had my max clock at 2040mhz and now having dropped that to max clock being 2010mhz I do not observe the issue. Anyone else care to try an underclock to confim this hypothesis?
