Proceeding the Elden Ring Network Stress Test Demo PS4 Scene Modding Recap and Bloodborne's Exploring & Restoring Developer PS4 Debug Menu Guide, recently PlayStation 4 Scene game modder @Whitehawkx (Twitter) revisited the Dark Souls III Network Stress Test PS4 Demo on Whitehawkx's YouTube Channel with menu help from @manfightdragon (Twitter aka LanceMcDonald on Twitch and WarpChair YouTube Channel) alongside patch help from @illusion0001 (Twitter and Illusion's YouTube Channel) showcasing several additions including the Dark Souls 3 PS4 Debug Menu, 60FPS, various resolutions and more demonstrated in the video below! 
The result is a collection of pre-patched PS4 PKGs via Py-Patch based on the Dark Souls III: Network Stress Test Patches recently added to Illusion's Blog and DarkSoulsIIINetworkStressTest-Orbis.yml Github page for Jailbroken PS4 Console owners to enjoy with a full Index of Game Patches also available.
Below is an excerpt from @Whitehawkx's CUSA03387 topic available to Verified Members (Verification Guide) in the private area:
Here's something fun I thought everyone would enjoy - the Dark Souls 3 Network Stress Test which was released back in 2015. I want to make something super clear up front: THIS IS A DEMO. IT IS NOT THE FULL GAME.
Alright, with that out of the way, let's continue. I spent quite a bit a time looking through the eboot and have unlocked multiple features. Let's start from the top.
These patches were provided by people other than myself:
The base game only has the net check bypass and video recording patches. Other than that it's STOCK.
Base: Size = 2.70 GB
720p60fps + all patches: Size = 102.56 MB
900p50fps + all patches: Size = 102.56 MB
1080p40fps + all patches: Size = 102.56 MB
1080p30fps proper frame pacing + all patches: Size = 102.56 MB

That should be enough flavors to cover everyone's needs. I will be submitting all the patches to illusion0002's github in the near future. So be on the lookout for those. Anyways, have fun!
