Pc Gaming: smooth on CX, jerky on C8


Well-known Member
Hi all,

So I’ve discovered something very odd when I connect my gaming PC to my OLED TVs.

I have an LG 65 inch C8 series. When I connect via HDMI to my 2080Ti, it runs fine at 1440p, but on some games (such as RDR 2) switching to 4k introduces some stutter or slower frame rate.

I’ve always put this down to the fact that the machine simply couldn’t handle 4K at steady 60fps.

HOWEVER: I’ve just purchased a new CX 48 inch series for upstairs and out of curiosity connected the PC to it.

The same games that previously had stutter/not 60fps are now suddenly silky smooth. Take the PC downstairs and connect to the C8 and the same silky smooth scenes upstairs are now jerky.

It’s most odd. Would welcome any advice from folks on how to sort it downstairs. I assume it’s something to do with refresh rates?

The C1 supports G-Sync the C8 does not support it.

That would be my first guess as to why its smoother, check if G-Sync is enabled in the NV control panel.
