Hey guys, I’m running Unreal 5.4.1 WINDOWS from source today, I improved editor performance by disabling Studio Telemetry, UDP and TCP messaging plugins, however, I still note that in editor I have lost 20fps from a 60fps scene and that my packaged performance is terrible. I have my game heavily optimised it has been from the start, I’ve been diligent about performance, measuring and finely balancing thread impacts as I go. Another example: where I was getting 70-90 fps in my open world with 5.3.2, now I get only 30~ fps. The thing to note here as well is that this is the frame rate when looking at the entire scene and when looking at the sky. As a test whenever looking at the sky I’ve always got 120 fps in previous engine versions.
