You can’t use the editor to mark performance like that.
First of all your scene is empty - the base cost being what it is is pointless.
Second. Its the editor. Doesnt tell you anything at all. Performance on it is based on whatever other windws are open or your pc/engine is doing.
You have to bench the final packaged result of something with the editor closed using fraps or something similar to know what to expect.
After setting up a proper “benchmark” scene.
Idk. Take Superposition as an example. UNIGINE Benchmarks
The idea is you have a set, well made scene, and you test things to know what sort of performance you should get before you make use of whatever it is in your final project.
Or, its also how you easily decide to move to better engines… if unreal cant hack it, it just can’t.
And chanches are it really can’t. Its not built around performance.
