With to respect to certain posts, My system should not have been struggling based on the scenario of where I was. I only run at 1440p as well.
Whilst I Don’t have a DDR5 system, a 4090 with a 5800X3D and 32GB 3600 should coast ultra settings @1440 (ultrawide)
As I have since posted, it seems to have been an odd isolated occurrence, possibly even network related.
