Portal RTX DLC with ray tracing and DLSS to be released in December (for Free)
Portal RTX will be updated in December; it'll be a totally free DLC that adds ray tracing to Valve's puzzle game, initially launched in 2007 btw.
Portal with RTX DLC will be available on Steam on December 8th. After that, anyone who has Portal on the game platform will be able to download the dlc for free. The RTX version will have path tracing support for realistic lighting and reflections and improved textures and models with greater quality. Nvidia previously released an RTX version of Quake II.
All ray-tracing graphics cards are supported by the updated game. For playable framerates with DLSS 2, Nvidia recommends its own RTX 30-series, actually the RTX 3080, whereas 40-series users benefit from DLSS 3(opens in new tab) and its Frame Generation technology. It is unclear how the game performs on AMD or Intel GPUs, but the absence of RTX 20-series GPUs means the processing and performance cost will be considerable.

Looking at system requirements table there are a few funny things there. First is that 3080 can only do 1080p 60fps (with DLSS). Second you need to use DLSS3 to get 4K 60 with a 4080. But as we know DLSS3 is intended for high refresh rate gaming. It feels atrocious at 60FPS with very high input lag. I tried DLSS3 at 60FPS and it felt like I was streaming the game over the cloud, maybe even worse than that. So what is Nvidia doing here lol?
At this point I don't ever see games using RT exclusively. 4090 can run Portal 2 native 4K at like 400FPS and with RT on it's 17 FPS. So 23x performance difference.

They originally said November, the promo video says November. And still waiting for CP2007 DLSS3 patch which was used to promote and review the 4090.
Anyway, really looking forward to playing Portal again.

Yeah it's not free when you have to buy a 3080 in order to play at 60 fps.
This game was a huge triumph even without rtx and it proves that good games gotta have an interesting gameplay gimmick.. they don't need realistic lighting.
The rays are a lie!

I like the sound of this! Those two Portal games, Portal 1 & Portal 2 were really great, and it's been so long since I've played them that I've probably forgotten all the puzzle solutions, so it's likely to be quite a fresh experience again. I like the fact that the recommended specs for the ray tracing are quite high - points to the idea that they might have really gone to town in creating widespread & pervasive "high quality" raytracing. I wonder if they're gonna give the same treatment to Portal 2?
