Checking my hz at different browsers i found that Opera is the only one capped at 60 hz in my case. My monitor run 75hz at 1920x1080, and works perfect and smooth in Chrome, Firefox, Edge and IExplorer.
I tried enabling/disabling smooth scrolling at opera://flags, and enabling/disabling hardware acceleration in opera settings. Nothing worked.
I have AMD Sapphire HD 7850 and Catalyst Crimson Edition 16.9.2
Anyone with 75hz or 144hz monitors can test in these pages and tell me if all is correct or capped at 60hz like me? Also i would like some tips to fix this problem. Thanks in advance.
