I just switched to a RX 7800xt from a 1080ti. My monitor has FS2 and worked fine with the 1080 but I get flickering with the 9800 if FS is set to the highest setting in games.. Anyone found a fix? Ta

Tried enhanced sync in the drivers? As your probs out of ur freesync range maybe if u have fsr on or something maybe? Or u can cap it to a few frames under ur monitors refresh rate top if 75 then 73 or 72?

Does any info here shine a light on the issue?

The variable refresh rate (VRR) range amounts to 48-144Hz when the ‘Ultimate’ mode is selected; the ‘Standard’ option is limited to 120-144Hz.

Now, the Samsung C49HG90 has three response time overdrive settings: Standard, Faster, and Fastest. However, the Faster and Fastest modes just enable the 1ms MPRT motion blur reduction (MBR) technology.

MBR eliminates motion blur by backlight strobing, but it sacrifices the maximum brightness in the process and it cannot be active at the same time as FreeSync.

To enable MBR, your refresh rate must be set to at least 100Hz. In order to prevent image duplications, your frame rate should be as close to the maximum refresh rate selected as possible. So, at 100Hz, it’s best to cap your frame rate to 100FPS, and then use either the Faster or Fastest mode according to your preference.

This also means that if you want to use FreeSync, you’re left with the Standard option, which is well-optimized for 144Hz, but at lower frame rates (and therefore lower refresh rate), the overdrive is too aggressive thereby introducing minor inverse ghosting.

So, at lower FPS (Frames Per Second), you might want to disable FreeSync for clearer motion at the cost of allowing screen tearing to occur, but thanks to the monitor’s high 144Hz refresh rate, tearing won’t be that noticeable.

Note that some units of the Samsung CHG90 are also affected by the FreeSync brightness flickering issue.

With the 1025 firmware (or newer), there’s the VRR Control option that fixes the brightness flickering issue with FreeSync/G-SYNC Compatible, but it can introduce some micro-stuttering as a side effect.

Perfect.. Thank you
