Game Ready & Studio Driver 595.79 FAQ/Discussion
LFC is broken on this driver and the 7 that have come before it. LFC engages too early (on a monitor with VRR range 48-240Hz, it will engage when a game is running at a stable 60fps, causing the monitor refresh rate to double to 120Hz, and leading to more perceived stutter). On drivers 581.80, and h

NS2 Edition is finally out
4K looks fantastic, but the image is juddering really bad for me when walking left and right (everything around me looks like it's shaking horizontally). It's really distracting. I have a ROG 4K OLED (PG27UCDM). Issue does not occur with any other games. I tried the 3.0 update before the Switch 2 Ed

No, don't buy OLED - Im done with this shit.
If he thinks the PG27UCDM has unbearably blurry text he's gonna lose his shit looking at the C5.

My OLED burn-in after 3000hrs.
I live in a very cold place when its winter and racked up 400h of gameplay in like 3+ months on bf6 I literally bought PG27UCDM today and saw that video and realized Im screwed. My 27GL850 has 17923h racked but is still good as new

Looking for a new 4k 32 inch glossy OLED… Recommendations?
If a Mac is your main machine, get the Studio Display XDR and forget about monitors for the next decade. I'm serious. I've tried from the PG27UCDM, ProArt PA27JCV, and finally the XDR. All of them pales in comparison to the XDR.
