This is related to the Global Illumination setting and the use of “rt_mixed_reflections” with the GI.

Have you customized your settings file at all? Try changing the Global Illumination setting and see if that fixes it. Make sure that rt_mixed_reflections is set to true to avoid this flickering.

I use a mod called More Graphics Options to make custom profiles to completely disable Global Illumination and disable rt_mixed_reflections. When doing this, I get this same surface flickering when launching the game. Setting the GI to “Low” and then back to “Off” fixes it when using the mod.

I already had the mod because I had to lower every option to the lowest. Just turning on GI didn’t fix it, I had to turn up the RTXGI slider to 1.0 for it to work. Works as it should now, thanks!

You can use these cutom presets I made that add forcing rt_mixed_reflections to toggle off when “Off” GI Preset is used and back “On” when any other preset is used. The flickering will ALWAYS happen if you start the game with rt_mixed_reflections = false and rtxgi_scale = 0.0 .

Install the zip with Vortex, or unzip it to your game root folder.
