Greetings everyone. So I have been trying to figure out how scanline sync works and hopefully benefit from this great feature. I own an ASUS ROG STRIX SCAR II gaming laptop paired with a GTX 1060 6GB and an i7 8750H. I am not the most demanding gamer in the world, I am extremely satisfied with 1080p@30fps at High settings but I hate tearing/stuttering with a passion. I usually go for a 30fps lock through RTSS and turn on Vsync to avoid tearing. I choose to accept the input lag and the micro stuttering this offers. Due to my laptop using the Nvidia Optimus technology, Half V-Sync/Fast Sync is not an option. I have been playing arround with the feature, setting Scanline Sync to x/2 and changing values from -1 all the way up to -300 with no difference at all. The tearline is still present and persistent. Vsync is turned off both in game and through the nvidia control panel and I am running the game at fullscreen. My question is, could this feature not be available due to Nvdia Optimus? Everything has to first go through the intel display adapter first, correct? Does this mess up with Scanline Sync maybe? Or am I doing something wrong? GPU utilisation is bellow 60 percent. I am trying this in games like the Witcher 3, AC Unity, Metro Exodus, Shadow of the Tomb Raider etc. Tearing is visible even at the menus where GPU utilisation is extremely low! Thanks in advance.
