Leo Torres shared a new video showing the Storm Coast from Dragon Age Inquisition on Unreal Engine 5. Dragon Age Inquisition came out in 2014 and used the Frostbite engine. While this video is just a fan project, it can give you an idea of the differences between Frostbite and Unreal Engine 5.
For comparison, you can also take a look at the video from the original version of Dragon Age Inquisition. This way you will be able to see all the improvements that UE5 brings. Also keep in mind that this “remake” is made by one artist, not an entire studio.
