Hi Leaderide,
I think the first step would be running the GPU profiler. While running in-editor press CTRL + Shift + Comma. This will show a breakdown of what’s taking up your frametime.
You can also use the console command showflag.xxxxxx 0 (Example showflag.staticmeshes 0 ) to toggle on/off features while playing to try and pinpoint any performance bottlenecks.
Cheers.
