NVIDIA RTX IO leverages GPU decompression for smaller data packages, enabling faster texture load times and lower CPU utilization, and allows developers to create a new generation of games with massive highly detailed worlds. 

NVIDIA RTX IO makes its debut alongside the free Portal: Prelude RTX mod today, and will also feature in Ratchet & Clank: Rift Apart, launching July 26th.

In Portal: Prelude RTX, NVIDIA RTX IO is always on (you don’t need to toggle it in a menu) and it enables much faster texture load time, minimizing asset pop-in:

Portal: Prelude RTX - Faster texture load times with RTX IO at 4K max settings, on a GeForce RTX 4090 and Samsung 980 Pro NVMe 

NVIDIA RTX IO also lowers Portal: Prelude RTX’s texture package install size by 44%, enabling gamers to enjoy nearly 32 GB of 4K textures loaded with lossless detail, while only taking up 18 GB of storage space.

For Portal: Prelude RTX, geometry was updated and upgraded in standard Half-Life Engine tools (Valve Hammer Editor), before being imported and automatically supported by RTX Remix, enabling fast iteration and development. Turns out, it's 2023 now, so that was 15 years ago, or 29 if you count the pandemic. To experience Portal: Prelude RTX at Ultra settings with path-traced ray tracing, NVIDIA DLSS 3 and a powerful GeForce RTX GPU are recommended.

Using NVIDIA DLSS 3, GeForce RTX 4080 and 4090 users will see performance multiply by 5X on average at 4K with max settings, delivering 80 FPS+ gameplay, for the definitive experience:

At 2560x1440, owners of the GeForce RTX 4070, and faster GPUs, can enjoy 80+ FPS gameplay at the Ultra Preset, which maxes out every setting.

Or in other words, RTX Remix is revolutionizing character replacements and upgrades in the same way it revolutionized asset replacement.

For Portal: Prelude RTX and future NVIDIA RTX Remix mods, the NVIDIA RTX Path Tracing SDK has been enhanced, improving denoiser performance and quality, which is particularly beneficial at lower resolutions, enabling gamers with older GeForce RTX GPUs to have a better experience.

Shader Execution Reordering (SER) dynamically reorganizes inefficient ray tracing workloads into considerably more efficient ones, further accelerating GeForce RTX 40 Series performance.

Opacity Micro Meshes (OMM) increase real-time performance and memory compression for complex geometry, further accelerating GeForce RTX 40 Series ray tracing performance, and with new CPU optimizations debuting in Portal: Prelude RTX, players receive even faster performance.

And of course, NVIDIA DLSS 3 and NVIDIA Reflex have both been upgraded to their newest versions for improved performance, even better image quality, and more responsive gameplay.

All of the enhancements, additions and improvements created for Portal: Prelude RTX will be incorporated into NVIDIA RTX Remix, benefitting all modders, and enabling superior updates to classic games.

Please note that members may not answer your question if they do not have the time to do it. In the near future, NVIDIA will begin sharing early access versions of RTX Remix with select modders to further refine the creator toolkit and runtime ahead of its official release later this year. Even with the incredible performance of NVMe SSDs, this goal has remained out of reach.

And more advanced geometry -that pushed the boundaries of the Source engine in 2008- enables more varied and aesthetically interesting uses of light and shadow. And its technology even more advanced.

During the course of Portal: Prelude’s story, players will encounter extremely challenging, advanced test chambers with more varied sights that with the power of RTX could well drop your jaw.

some GeForce RTX 20 and 30 Series GPUs), the easiest path to better performance is to use GeForce Experience. Pinpoint accuracy and timing are key to overcoming Portal: Prelude RTX’s most difficult challenges, and using NVIDIA Reflex system latency is reduced, making gameplay smooth and more responsive, delivering the reaction time needed in critical moments.

Coming soon, those without a GeForce RTX GPU can stream it on GeForce NOW without worrying about system specs or download times. Upgrade to an Ultimate membership for the power of an RTX 4080 gaming rig in the cloud and crank those settings up.

The Best Responsiveness With NVIDIA Reflex

As NVIDIA DLSS revolutionized scaling and performance, NVIDIA Reflex has revolutionized low latency gaming, giving multiplayer gamers a competitive advantage, and making single-player games incredibly responsive.

Yet, somehow, I've been coaxed into releasing one last version that includes all of the patches and fixes added over these years to keep this mod playable in the face of an ever-changing Steam platform.

I'm deeply grateful to the community and the players that still message me relentlessly after all this time, whether it's to praise the mod, provide ideas or feedback (quite late), ask me whether I'm working on a remaster or whether they should work on a remaster (spoiler alert: no), or less kind messages altogether of course.

It’s optimized for Portal: Prelude RTX, Ratchet & Clank: Rift Apart, and other games, and gives you the highest levels of performance when using NVIDIA RTX IO in the two titles.

To download and install, head to the Drivers tab of GeForce Experience or GeForce.com.

Portal: Prelude RTX Available Today!

Portal: Prelude RTX, made by just a few people, demonstrates the possibilities of NVIDIA RTX Remix, enabling modders to remaster and remake games, total conversions, and unofficial prequels with relative ease.

Created by Nicolas “NykO18” Grevet and others, Portal: Prelude is an unofficial Portal prequel, set before the time of GLaDOS, featuring a new extremely challenging 8-10 hour campaign composed of 19 new test chambers, new advanced gameplay mechanics, a fully voiced story with NPCs, and a whole lot more.

Portal: Prelude RTX is available today to download from Steam, for free!

Portal: Prelude RTX is remastered with full ray tracing (also known as path tracing), DLSS 3, Reflex and the newly-launched NVIDIA RTX IO to deliver an even more immersive experience for gamers.
