SOLVED: Citrix was causing problems. I uninstalled Citrix as suggested in the posts below, and issue went away.
I cannot play at all. I’m getting 1-3 frames per second, even at pre-game hero select screen. In-game is about the same.
The game has run flawlessly for the last couple of years on my computer. I have not made any recent software or hardware changes. I have not made any changes to my router or ISP. I have a hardwired connection to my router, so it isn’t a wireless issue. Internet speed tests show there are no issues with my connection.
All other games, including Blizzard games running through Battlenet work fine.
I have tried closing all non-essential background processes, but this did not help.
I have reinstalled the game, updated my BIOS, updated my video card drivers, flushed DNS, uninstalled game & deleted all profile data, re-installed to a different hard drive, updated router firmware, and even cursed at my neighbor’s dog (I was irritable and figured it couldn’t hurt). Not sure what else to do.
Is this a regional issue or something else? I am located on the gulf coast in North America.
