On opening the inventory screen I was getting fps drops <10 fps followed by a hang. Needed to use task manager to force close.

Problems started when switching down from 4k to 1440p.

I am running an RTX 260 and 5820k with 16gb of ram. Latest drivers.

I have resolved the issue by switching the general graphics quality down to low. It was on high. This has resolved the issues for now it seems. Obviously, this is a temporary fix.
