Please refrain from bumping or asking for updates. We handle issues as they are assigned and are diligently working to handle any and all questions presented by the community.
I have a few questions in order to clarify what you are doing with your scene and what platform you are packaging to.
1.) What platform are you packaging to? Windows, Mac, IOS, Android ?
2.) If you are packing to windows do you have a Post Processing Volume in this scene? Are there any features in it that could possibly lighten the scene you have?
3.) Do you have a lightmass importance volume in your scene?
4.) Can you package a blank project with starter content out and still see the same thing?
After I have this information I will continue to investigate this issue.
I believe I see the issue. The fire particle you are using calls upon your the amount of VRAM you have. I see that you are limited to 4GB. We typically recommend 8GB for developing with UE4. It could be that the light you are using, in conjunction with your particle was causing the lag because your computer’s calculations were being maxed. Try putting the light back in and bringing up your Task Manager. With that open and on the " Performance " tab you can see how much memory your machine is using.
This is a link to our forums where a user named KorkuVeren goes through his system spec’s and where he got them. It is at the upper end of what you are looking for but you may be able to find some better deals with the holidays. This also requires you to put this together yourself. If you are unfamiliar with how to assemble a PC then you may use these spec’s to shop around find a machine that is comparable.
