Hey there  

So i used to be making an attempt to play Soldier of Fortune on my arc a770 nevertheless it doesn´t run that grad as a result of its stuttering and im getting a blinking ethernet port icon on the higher left of my display(why ethernet? lol).

A fast google search instructed me that this can be a frequent situation and it’s essential to deactivate gsync or vsync SOF 1: If You Have Stuttering/Lagging Motion, web page 1 – Discussion board – GOG.com. I simply don´t understand how to try this on my arc card. 
Any concepts? 

Thanks!

Edit:  …im an fool. I all the time neglect concerning the Arc Controll middle…

For the one man googling that in a 12 months or two: 

Go into the Arc Controll Heart

Open the Settings-> World Recreation Settings -> Mode for Tearing: VSync off.
