I have recently returned to the game after a several month absence. Previously, I had no problems with running the game, but now I am constantly experiencing game crashes. This has happened on various maps with different characters and under various conditions (combat, standing still, running down the street, the character select screen, etc). I have no new hardware or software changes (other than windows and driver updates) since my last time playing.
In an effort to stop the crashing, I uninstalled the game, cleaned the registry with CCleaner, restarted the machine, and reinstalled the game. The problem still exists. I believe the issue to be graphics card/driver related (see Event Viewer info below), so I rolled my NVIDIA driver back from version 445.87, release date: 04/15/2020, to the previous version (442.74, release date: March 19, 2020). The problem remained. I have reduced the graphics settings to their lowest (something I've never had to do before while playing) and it does not stop the random crashing. I also have ran several troubleshooters (NVIDIA, Microsoft, etc) on the video card and they all come back good.
I haven't experienced this issue with any other applications or games. Specifically, I have tried to recreate the graphics crashes with Fallout 76, World of Warcraft, Warhammer Return of Reckoning (private server) and various windows applications. So far it only happens in City of Heroes. I'm at a loss of what's going on. I opened a support ticket, but wanted to share my story here incase anyone has any insight or suggestions.
Here are my computer's stats:
Windows 10 64bit
Intel Processor i7-4930k CPU@3.40GHz
NVIDIA GeForce GTX 780 video card
28 GB RAM

The game is pretty much currently unplayable. Which sucks because I was really enjoying myself. Thanks for taking a look at this and any suggestions you might have to fix my issue.
