Hello colleagues, I am working on a project in Unreal Engine 5.7 on a MacBook M2 that has 8GB of RAM. At a semi-empty level, I get 1-10 frames per second. I wanted to find out how to enhance the frames in the editor so that at least I could work with objects. ---

Turn off shadow on the directional light. Or, working unlit mode 🙂 ---

Unfortunately not enough ---

it turned out that I did this: Disable or reduce the quality of resource-intensive functions: Disable Nanite and Virtual Shadow Maps in the project settings. Use Lumen software ray tracing by disabling Hardware Ray Tracing. Disable or minimize post-effects in the viewer (Post-Processing). Reduce granularity and memory usage: Lower the resolution of the textures (import with smaller sizes). Combine meshes to reduce the number of draw calls. Use LOD models with a low polygon number at a distance. Optimize your editor and work environment: Close all unused applications on the Mac to increase the available memory. In the editor, disable the automatic compilation and updating of assets in case of changes. Use the “Save Layout” function in a lighter and simpler way, without active tabs and windows. Use console commands to monitor and improve: Enable FPS statistics: stat fps, stat unit. Limit the editor’s frame rate to t.MaxFPS (for example, t.MaxFPS 60 or less) for predictable load. ---

> [@MrDmitry](#): > > Use Lumen software ray tracing by disabling Hardware Ray Tracing. that shouldn’t give you more performance but the opposite. you can reduce the quality of materials and reduce the screen percentage on the scalability settings menu. ---

The results speak for themselves… Turning off “Support Hardware Raytracing” was literally all I needed to do to fix the excessively sluggish editor performance. Didn’t need to touch any of his other proposed suggestions. It’s now both extremely snappy and responsive in the editor, and it doesn’t take 10 seconds for the fps to stabilize in play mode ---

cool, it might well be that your hardware doesn’t support proper hwrt and may be emulating it. or maybe something else happens. glad you find it.
