Last week, NVIDIA released a new Path Tracing Tech Demo that everyone can download and try, called Bonsai Diorama. Using the NVIDIA RTX Branch of Unreal Engine (NvRTX), this is an optimized and feature-rich branch that contains all the latest NVIDIA rendering technologies for Unreal Engine devs.
The demo showcases RTX Mega Geometry, along with ReSTIR Path Tracing and DLSS 4. The demo only has one bonsai tree that packs a lot of detail. So, it may not impress some of you who were expecting something like the Zora Demo.
You can go ahead and download the demo from this link. Alongside the Bonsai Diorama Tech Demo, you’ll also find the RTX Amusement Park Demo. That demo features RTX Dynamic Illumination rendering over 1,000 shadow-casting lights in real time. It’s another cool tech demo you can try on your NVIDIA RTX GPU.
Speaking of Unreal Engine 5, I recommend trying out these other free fan-made demos. You can grab a Superman UE5 Demo, a Halo 3: ODST Remake, and a Spider-Man UE5 Demo. There’s also a fan-made version of STALKER in Unreal Engine 5. If you love old-school FPS games, you should check out this remake of the classic FPS Blood in Epic’s engine. For Mario fans, we have this cool Super Mario Galaxy Tech Demo in Unreal Engine 5.
And that’s not all. There is a cool remake of Halo: Combat Evolved’s Halo level in UE5 that you can download. Or how about this free Attack on Titan game? Then we have the fan remakes for Dino Crisis 2 and MediEvil 2. Plus, there is an amazing fan remake of Sonic Adventure 2, called Sonic Adventure 2 Redux. Oh, and let’s not forget the amazing ports of Skyrim and Oblivion.
Owners of high-end GPUs can also try these two tech demos. The first one features a Witcher-like environment. The second shows off a Rome Italian Town. Last month, we also shared a demo of King’s Field 2 in UE5. Finally, we have The Lord of the Rings: Conquest Reimagined in Unreal Engine 5, a remake of Flappy Bird, a demo for Need for Speed: Underground 2, and a Diablo 2 Remake Demo. They all look awesome, so be sure to give them a try.
Enjoy and stay tuned for more!
