Portal RTX Is a Ray-Traced Remix of the Puzzle Classic


As part of Nvidia's GTC keynote today, the company announced Portal RTX — an RTX-enhanced version of the 2007 puzzle classic developed by Valve.

Portal RTX includes updated graphics and supports ray tracing. This is not the first time Nvidia has made RTX upgrades to older games. The company previously made RTX versions of Quake II and Minecraft. However, this latest RTX remix game is special because Nvidia confirmed that the tool used to make Portal RTX, called RTX Remix, will be available to all for free. Meaning others will access the tool and make their own RTX-enhanced games.

Portal RTX was one of many announcements Nvidia made during its GTC keynote. Other announcements include the unveiling of the long-awaited RTX 40-series, which consists of the RTX 4090 and two RTX 4080 GPUs: one with 12GB of memory and another with 16GB.
