Always during combat. I’ll be fighting packs (or a boss), and my game will suddenly just lock up. It will sometimes recover just enough for maybe ten more frames to pass, after which it locks again and I am forced to kill the client. This just keeps happening. Doesn’t happen in every run.
I have already tried a clean install, made sure all drivers are up to date, made sure all addons are up to date, and done a few runs with no addons whatsoever just to be sure. Game continues to do this with or without addons.
Sounds like a app hang, possibly caused by a memory leak. Not sure, and no information to go off of for a quick diagnosis. Such as what kind of PC, what OS, etc. You could run a DXDIAG, save it, and go through the error buckets on the bottom, see if anything stands out.
