The problem with GUI settings is that the result is not apparent, and there might be side effects. I do not find spending half day on trying out setting combinations as productive work. I have looked into SRP and i do still consider that as an option, and also replacing the shaders. But i have doubts regarding the SRP, for example i have looked at the code that sorts lights in Forward+. The individual light calculations are not much, but its still done trough the job system. I imagine if there are hundreds of lights, then that would make sense, but for 2-5 lights, it seems like a waste. So it might be optimised to scale, but not for my case. Is the effort of replacing the SRP worth it, and is the performance comparable to putting together/reusing an engine in C++? It is also a bigger commitment, as it needs to be coded on a different level and in a way very specific to the engine. Better than having to reverse asset file formats, but still very specific to the engine.
