@frostic , NBraz is getting 88fps in that screenshot so I’m not sure it is performance that is his problem (specifically with this scene) - though I agree 100% with the needing beefy computer comment.
@NBraz is this a fresh UE5 project or one converted from a UE4 project. I wonder if it is something odd with the roughness or normals on the table.
Have you created the same scene if 4.26 to see if the same issue exists.
