I changed some things like having small icons on the toolbar, showing FPS and memory on the top-right corner, putting the content browser to the left as it was in previous versions, and not much more I think. Scalability settings I always have them at the maximum level. My PC can handle very well my scenes. In my actual scene, the problem got fixed magically before upgrading to 4.7.5. The stripped down version of the scene that I uploaded still has this problem. That ini file is constantly changing. Maybe there was something there that can cause conflict and now it isn’t there and that’s why my actual scene works ok now?
