Materials in the content browser and Material preview looks super noisy

Why are my preview looking this noisy and how can I fix it? This is unreal 5.5.

Hello there @Yggdrasild!

Hello there!

That’s very peculiar, my first guess would be a display drivers conflict. Try refreshing them, and pick the “Clean Installation” option, as well as going for the “Developer” drivers.

If the issue persists after that, please test the following alternatives:

• Disable any active overlays in your system, either nVidia Experience, or the Xbox Game Bar
• Since you are working on UE5.5, test switching between DX11 and DX12
• Adjust your values for engine scalability

Changing from DX12 to DX11 did seem to fix the issue.

But what do I lose by downgrading? Any Lumen, Nanite, Pathtracing functionality?
