Hi, guys, I'm working on a PC project that is relatively large and my experiences with UnityEditor is that it's so slow and it's becoming unbearable as it's getting bigger each day. I'm trying to understand why it's slow so that I can figure out what to do about it. If it cannot be fixed, I probably have to quit the job since the project is committed to Unity for now. 1. Starting Editor with my project takes about 3 min. When loaded, it uses about 3GB Ram. The project size is about 50GB, therefore it's not trying to load the entire project into the memory. If so, why does it take so long to load? UnityEditor crashes quite often and it seems to slow down as I use, thus I need to restart the editor every once in a while and it's getting really annoying. I wouldn't care about the loading time as much if it doesn't crash that often and doesn't slow down over time. 2. Press "Play" takes about 15 seconds to go into play mode with a simple test scene with 100s of GameObejcts. What is it trying to do? And there is no message. 3. Saving a simple scene with 100s of GameObjects takes about 3 minutes and the editor is unresponsive. Again there is no message. I described the problem with saving a scene here in more details. I have pretty highend spec machine and I assure you it's not my system. https://forum.unity.com/threads/perforce-plugin-so-slow.600460/ 3. Quitting UnityEditor takes about a couple of minutes. Again, no message. What is it trying to do? I come from Unreal, and most of the task is much quicker. "Play" is almost instant and starting the Editor and asset imports are much quicker. I like Unity because of the faster compile time(compare to UE) but it looses all of its advantages in many other areas and it leaves a very bad impression and I'm starting to regret that I gave it a try but the project is committed to Unity and I'm very unhappy state at this moment. Unity is pushing "Performance by Default" slogan lately quite a lot. It's all good but it should start with the Editor first where we spend many many hours!!! I appreciate if someone can help me understand what's going on. Cheers!
