NVIDIA DLSS 3.5 and Half-Life 2 RTX announced

By - | Views: 30,544

Today NVIDIA announced DLSS 3.5 further enhancing Ray Tracing and Half-Life 2 RTX was also announced. So let's go over the details.

Firstly Half-Life 2 RTX is being built by the community. Four top Half-Life 2 modding teams have come together including the people behind Half-Life 2: VR, Half-Life 2: Remade Assets, Project 17, and Raising the Bar: Redux under the banner of Orbifold Studios. They've been given access to the latest RTX Remix and they're rebuilding materials with Physically Based Rendering (PBR) properties, adding extra geometric detail via Valve’s Hammer editor, and leveraging NVIDIA technologies including full ray tracing, DLSS 3, Reflex, and RTX IO.

You can see a lot more in the NVIDIA announcement. The project also has a dedicated website. Like previous RTX remasters, it will probably not have Native Linux support but will be playable with Proton.

The other big one is NVIDIA DLSS 3.5 that NVIDIA say features "Ray Reconstruction, a new AI model that creates higher quality ray-traced images for intensive ray-traced games and apps". It is trained with "5x" more data than DLSS 3, and recognises more ray-traced effects that NVIDIA say allow it to "make smarter decisions about using temporal and spatial data, and to retain high frequency information for superior-quality upscaling". So basically put it's supposed to continue making ray-tracing look better, while also giving you potentially better performance.

You can see an example of it below with Cyberpunk 2077 and below that is a Tech Talk with NVIDIA VP of Applied Deep Learning Research, Bryan Catanzaro:

Additionally the previously released Portal with RTX will also be getting an upgrade to use DLSS 3.5 "later this fall", along side an update to the NVIDIA RTX Remix used for it that improves performance and the quality of path tracing for older graphics cards.

I've got a 7900XTX and I'm excited for my fellow Team Green gamers! I wish you all could afford 4090s… and I wish they had better Wayland support.

Man, Quake II RTX has native Linux support. Why can't this or Portal? Half-Life 2 and Portal already have native Linux versions. I don't know how modding works internally. But doesn't that automatically help make it possible? </3

I don't care about RTX, but those new models and textures 🤩...

Looking at the old/new visual differences, I feel like the new RTX version doesn't capture the same kind of feel as the original.
Also, I'm totally uninterested in the push for proprietary vendor-locked software.

Make possible yes but the modders are apparently Windows devs and have zero clue or interest on how to code for Linux.

Neato!

Is this a continuation of the Remastered Collection? I think it was created by the same people who did the Remade Assets?

I was commenting on this to some friends earlier. The RT looks great, but it seems like the original has something of a blue-grayish tint giving it a general mood that is removed on the RTX version.

Because it is using RTX-remix, it's not being done in source code.

I don't have an adequate card for fully path-traced games, and this doesn't make me any more willing to go back to team green or to upgrade to a better team red card just for path tracing. Whatever.

It's funny how they showcased it on the scene where added visual fidelity matters the least. The original Source variant looks plenty good.
