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. I can see from looking at the forums that this seems to be an issue being reported on Mac, Linux and Windows. Can we get some guidance please on a fix, wasn’t Unreal 5.4 supposed to be faster? Also to note, to install 5.4.1 I had to remove the latest MSVC toolchain from Visual Studio, which I eventually find is marked as banned by Epic, (had to dig to find this info which I felt needs to be published in more places), that then I found out that doing that had corrupted my Unreal 5.3.2 engine. I also now can’t rebuild even from a fresh source of 5.3.2 today, I get 10K errors.
