That's unfortunate! I was honestly expecting something like this to happen though as I didn't really have the opportunity to test on anything other than my machine (I have a pretty powerful computer: RTX 3080 & Ryzen 9 5900X). That being said, there's plenty of room for performance enhancements in my engine that I just simply didn't have the time to implement, some of those include instanced rendering and a cache friendly ECS.
