I created a blank project in Unreal 5.3.2
In order to do so, I unselected every option on project creation screen and created a blank project as shown below.

Despite that some landscapes got added to the level, wondering what is the meaning of blank project then. Nevertheless, I was getting the “Video memory has been exhausted” error everytime I start unreal and there was horrible lag. I turned the scalability setting to low in the toolbar and the error went away.

However, I created a new blank level and it thankfully had no landscapes in it, still the error kept coming back about the video memory. I have a good capacity external GPU connected to my system, why do I keep getting this error then ? How do I fix it, I am unable to work at all.
