Add me to the list of those increasingly affected; hoping for a resolution.
Glad I found this thread. I hadn't seen this issue in any other app/game, but was almost sure that a too-warm GPU was the cause. Good to see that someone with this issue already tried underclocking, and also many other would-be remedies that would have cost me $$$ to end up back where I started.
Like i said in the first post, it gives the same symptoms of a failing/ overheating gpu, but it is in fact the game...
ZOS you EVER going to address this, or just keep ignoring it? At least tell us if this issue is even fixable.
This thread should be bumped until we get some type of ZOS response.
This issue has been around for a long time, and at times I even get a loading screen when it happens. Makes the game totally unplayable.
