As revealed by Alen Ladavac Croteam / Serious Sam 4 technology lead at the GCD 2019, Serious Sam 4: Planet Badass will use General Purpose GPU computing to generate its 128x128 km map down to 1.5cm detail. They turned to procedural methods, because that amount of data would take an insane amount of storage. In the vicinity of 100TB. Due to the sheer size of the planned map Croteam knew they needed some type of procedural solution from the start. So instead of storing the actual map and scenery objects like rocks and vegetation as finished models, they devised a method where they only store templates that can be used to generate the actual models from scratch on the target system. This means that they could fit the entire 16384 km2 map into about 200MB of storage. It will be interesting to see what amount of VRAM and GPU will the game require for this, and will it reduce terrain detail if the available video memory is less than the recommended amount? Serious Sam 4: Planet Badass is rumored to be released sometime in 2019, but the exact date is not known yet.
