As mentioned by others, Descent used portal rendering all the way back in 1995. It's a simple trick that only requires an alpha mask, which even the earliest hardware supported.
But certainly the game Portal (2007) hyped using portals for rendering prior to Prey.

- Tempat 2y agoAlso worth noting that Prey (2006) started development in 1995.
- keyringlight 2y agoThere are a handful of videos from E3 (97 or 98) showing off the original 3DRealms development of Prey. One of the things that didn't survive into Human Head's version on the Doom3 engine was rotating portals, or if they did they were rare that I don't remember them.
- bananaboy 2y agoOriginal Descent was software rendered though.
- adastra22 2y ago2D graphics cards had alpha masking.
