I have Origin and Battlefield 3 and prefer to launch BF3 via Steam. The game runs fine, but when I launch Origin occasionally gives a warning that Cloud Saves can only be used when launching via Origin.
I'm not sure what this is supposed to mean; launching via Steam still opens/authenticates via Origin and takes me to the Battlelog website, the game works fine and it runs the Cloud Save sync before stating the game. However I've noticed that it seems to occasionally cause sync conflicts when starting the game.
If I play Origin games via Steam, is it not uploading my Cloud Save files to Origin or what? I only have one PC, so conflicts aren't a huge problem, but do want my files backed up in the cloud. Origin is of course installed, so if necessary I can just launch BF3 through that.
