Re: updated to the new EA app. Now Crysis 3 will not open or update
Here is an actual fix.
Restart your PC and close EA if you have it running
Open Powershell as an administrator and use the following code:
Remove-Item -LiteralPath "Y:\Origin\Crysis 3\dlc" -Force -Recurse
Replace Y:\Origin\Crysis 3\dlc with whatever path you have Crysis 3 installed to, just make sure it points to the DLC folder.
Open EA again and you should be rid of the Lost Island DLC which causes the issue.
If that doesn't work you might have to take ownership of the Crysis 3 folder, give yourself the highest permission and try the above again.
Be aware that if you input the wrong directory it will be deleted without asking you are sure so be very careful with what you enter!
EDIT: The non remastered version is busted on modern AMD cards, all kinds of framerate issues and capped at 64FPS.
Apparently there are workarounds for this but I don't trust Rivatuner at all to not install other junk by itself when you get the software.
