My other monitor was only up to 60hz as well. I have done a few things and have seemed to make it stable. I put my second monitor to run off the integrated graphics card, and I changed my page filing to be: Min: 1024 x GB of Ram Max: 1.5 x Min So for me, I have 8gb of ram: Min: 1024 x 8 = 8192 Max: 8192 x 1.5 = 12288 To get to your page filing, go to Control Panel/System and security/ advanced system settings/under performance click settings/advanced tab and click change. Hopefully this works for you too and brings some stability. I have not had to reset my game to fix any stutters for a few days now.
