recently my gtx 650 died and brcause it is only 20% faster then the igpu on my i5 8600k i started to use it but there was a problem my gygabyte Z370 ulta gaming (rev 1.0) only had digital connectors witch was fine for my primary monitor witch works with vga and dvi but my secondary monitor was vga only and i didn't want to buy an adapter so i just installed an old geforce 8500gt i pulled from an old pc and installed it because it had vga, dvi and s video and to use my igu instead of the pc passing the signal from the 8500 gt to ihe igpu first i changed in the bios rhat the igpu is always on so that i can conect a monitor to it and i fired up fortenite .....and it didn't work so i disabled ithe 8500gt in device manger and that did the trick so now the 8500 gt is now just a vga adapter to but the now my second monitor the one connected to the 8500gt chops even if i just move a window around.
can someone tell me if i can fix the screen taering or not.
