The three games I have that are hurting my 1080 are: Metro Exodus, Odyssey and BFV.
At 1400p they require something a bit more than a 1080. For Ultra any way.
I have Metro at high with most settings turned off other wise too low fps.
Odyssey is a killer. Especially in 4k HDR even with a 1080ti. The other two hold up well with it though.
