This flickering happens no matter what project I have open. I have tried a lot of things, tinkering with exposure, static lighting which is baked using GPU lightmass, raising and lowering brightness of lights, increasing gather quality, lumen detail levels, etc. The video shows you a scene I got from FAB and this issue happens in my own projects as well.
The only way to reduce it slightly is to use hit lighting instead of surface cache but that only helps a little bit and the noise remains. I’ve been banging my head with this for a while and I simply don’t understand. Maybe something’s wrong with my GPU? But all drivers are up to date, I even reset the radeon settings and tried various profiles and all.
CPU: Ryzen 5 3600
GPU: AMD RX6600
AMD drivers up to date, adrenaline software global settings set to default.
Checking around the community, flickering in heavy projects can happen from time to time, due a variety of factors. But you shouldn’t get them in ANY project you are opening. Still, there are ways to deal with this issue, let’s try to implement some of them:
The first step, you already covered partially, by updating your drivers. Please do the same for your OS, ensure that nothing is pending there
Then, test disabling Nanite for your reflective meshes
Next, disable high quality reflections and screen traces from console command. These features are usual suspects for similar flickering cases:
Finally, test by adjusting the current value for rendering the reflection resolution. Go to Project Settings > Engine > Rendering, and look for the Reflections option. From there, increase the resolution value to improve reflection quality:
For further methods to improve reflections, I suggest following this guide
Now, if the issue persists at this point, we would need to focus back on your general setup. Use the -dx11 tag to force the engine into DirectX11, and check if the reflections still flicker.
Was the problem occuring with previous versions of UE and/or your current set of drivers? If no, then use DDU to completely remove your drivers, and replace them with the previous iteration, which then you should test in a previous UE build, like 5.6.
