Sadly these 2 options don't work, due to the restrictions of the Geforce virtual machine environment. I can only get to Steam while the game is running, and i I set the launch argument above, it isn't preserved to the next session, so when I restart to have the arguments take effect, they are lost when the session ends and the new session doesn't have any arguments.
Plan B would be to select the older version, but Steam won't let me select a different version to the latest. Not sure if that is because the game is running, or a Geforce steam limitation.
Any other suggestions? Alternately might a future patch address this?
Thanks
