Yeah the main thing i notice playing at 240 vs 120 is the ability to track the other players when they are moving around the screen , they just seem so much easier to notice and target which makes me feel like I'm cheating at times but is what it is
The difference from 60 to 120 is a massive jump and noticeable in every area, the jump from 120 to 240 not as noticeable but does feel nicer for sure . i think a lot of this has to do with playing on an oled at 120hz which has instant response times and even my new monitor ( PG279QM ) isn't as fast as can be seen in the HWU oled review
You will double your fps and then some when dropping from 4k to 1440p on a 6900xt i reckon , will be very interested to see what it does . This is using DLSS ( FSR identical ) . Will pop a video up later today
