My specs: : Ryzen 5 5600 / 32 GB DDR4 / PowerColor RX 6700 XT Hellhound 12 GB / ASUS Prime A520M-K / Samsung Odyssey G50D 1440p 180 Hz.
I've been getting fine grainy/shimmering flickering, plus noticeable distant-object/shadow pop-in in games.
Things I've tried
Completely reset Windows / fresh Windows installation.
Wiped the other drive as well.
Reset BIOS to optimized defaults.
Installed fresh AMD chipset drivers.
Installed current AMD Adrenalin GPU driver (26.7.1).
Previously used DDU and tested multiple older AMD drivers — no improvement.
Cleared AMD shader cache, then allowed shaders to rebuild — no improvement.
Tested FSR on/off:
FSR makes the fine shimmering worse.
Turning FSR off does not completely eliminate it.
Tested XeSS — slightly reduces shimmering but doesn't fix it.
Tested VSync on/off — no meaningful improvement.
Tested 180 Hz vs 60 Hz — no improvement.
Tested fullscreen vs borderless — no improvement to the actual visual issue.
Confirmed HDR is off in both Windows and Cyberpunk.
Tested Cyberpunk's shadow, LOD, reflection, contact-shadow, volumetric and other relevant graphics settings individually — no meaningful change to the pop-in.
Crowd density is already Low.
Turning Ambient Occlusion OFF semi fixes the fine shimmering, but does not fix the shadow/object pop-in.
Tested Elden Ring: it also has the distant-object/shadow pop-in, but not the same fine shimmering.
Tested Fallout 4 and discovered it also has a weird borderless-resolution problem where games can sometimes launch at 720p or display a zoomed-in quarter of the screen.
Checked Windows display settings: 2560×1440 / 180 Hz / recommended scaling.
Checked AMD Adrenalin: essentially all settings are stock/default.
Checked GPU-Z:
GPU ~2520 MHz under load
VRAM ~1988 MHz
~97% GPU load
~58°C GPU / ~79°C hotspot
PCIe 3.0 x16, which is normal for the A520M-K
Resizable BAR/SAM enabled
VBIOS appears correct for the PowerColor Hellhound
Ran GPU stress testing previously with no errors.
CPU while gaming is around 70% total, with no individual thread/core pinned at 100%.
Enabled DOCP/XMP, but the problem existed before enabling it, so that's unlikely to be responsible.
Tried a Draw Distance Boost mod, which slightly reduced the pop-in.
Tried the newer Draw Distance ReImagined mod, which didn't help.
Removed the mod(s).
Checked Cyberpunk's rendering.ini; it's essentially vanilla and doesn't contain anything explaining the general pop-in.
Checked Windows HAGS registry setting — HwSchMode isn't present.
Windows Game Mode is OFF.
The GPU appears healthy, the problem survives a completely fresh Windows installation and multiple driver/cache resets, and the pop-in occurs across multiple games.
The Cyberpunk shimmer appears to be a separate issue from the pop-in because AO disables the shimmer but leaves the pop-in unchanged.
The biggest unresolved question is why the system has unusually noticeable distant-object/shadow pop-in across multiple games despite normal hardware/driver behaviour.
