You would actually need to do have to reproduce the exact same process with the same time on both versions and profile both to contrast the data and see where performance changed for your machine. In my case I haven’t notice any particular change when profiling. In any case having a higher CPU usage doesn’t necessarily means that it’s worse if whatever was happening on the previous version is now done with a lower wall-clock time. I think you would actually need to have some specific performance optimization knowledge to tackle this.
What you may want to do is ask Epic if it seems reasonable to have some kind of editor benchmark to keep track of performance across versions. I asked a question related to that on a Twitch stream and here is the answer: - YouTube I still think it would make sense to have some automated process to track performance regressions but I’m don’t know about enough about the editor to implement that myself and I already got some other stuff in my plate right now.
