Portal is being released with RTX, which will see the game''s graphics reimagined "with full ray tracing and entirely new art evocative of the original."
Nvidia said in a detailed blog post that "full ray tracing" will mean every level will be changed. Light will now bounce around the settings, and "be affected by the scene''s geometry and materials." In the meantime, shadows will be "pixel perfect."
"Portal''s unique selling point is the ability to take anything through a portal and see through them, something that had never been completed before," Nvidia said. "With ray tracing, light will flow through portals, causing shadows to shift in step."
This is the new look Portal, which was developed by Lightspeed Studios, which has a long-standing tradition of Minecraft and Quake 2. In addition, it has also used a new tool known as the Nvidia RTX Remix modding platform.
Nvidia said that, with this tool in play, "the game runs in the background and [it [removes] the old rendering APIs and systems with the 64-bit Vulkan renderer" this means that it will enable "any addition of ray-tracing to classic games and it all updates in real-time as lights and objects move."
Portal with RTX is coming this November, which is now available as a "DLC" for the Steam version of the game, where you can wishlist it right now. Along with this, Nvidia has announced that it will be launching its modding tool for free, which allows users to "add ray tracing with just a few clicks," as well as providing "modders the tools to make ambitious remasters even for previous games."
