I upgraded my system from RX 560 to GTX 1650 Super. I have a 75Hz FreeSync monitor and It was working perfectly enough with my RX 560 at 75Hz. But I use 1650 SUPER now and it shows my Hz as 74,924 Hz. This is not a problem but when i use this setting its almost life 30Hz refreshing rate. When I take it back to 60 Hz its kinda normal. I use DisplayPort and every single software is up to date.
