Portal begins by demonstrating through hands-on experimentation how portals work, and which surfaces you can use. When you first gain the Aperture Science Handheld Portal Device, or the "portal gun", you can only place one portal, with the other fixed. It doesn't take long to grasp. "When we introduce a new mechanic, we'll playtest that and see if the player got it right away, if he was really confused, or just didn't get it at all, we have to go back to the drawing board," says Swift. "We just kept iterating on that until we found a good way to train players. Now we're able to teach them really complex mechanics and tricks." The benefits of this approach are apparent throughout. By the time the second portal is introduced, you're well into your stride, and happy to start firing them off. Left-click for blue, right-click for orange. Another example is the "funnelling" toggle in the options menu. Enabled, the game gives you a bit of help jumping or bouncing things through portals, without stopping you dead because you snagged the boundary by a pixel or two. Good work, playtesters.

Today, Portal with RTX is being upgraded with DLSS 4 with Multi Frame Generation, multiplying framerates, as well as the transformer model for Ray Reconstruction and DLAA, enabling even better image quality. Portal with RTX is also adding RTX Neural Radiance Cache (NRC), a neural shader that improves indirect lighting, as well as a bevy of performance optimizations.

A gameplay demo of the cancelled Portal prequel F-Stop using recreated assets features no portals, and a unique camera that duplicates items.

From GamesReviews:"Portal with RTX is a fresh look for the 2007 classic. But it's not easy to run, and the results may not impress everybody."
...but this game looks maaaaad booring.
It doesn't quite catch my attention either.
Can't wait to get this game with TF2 and HL2:EP2 for the PC. This game looks awesome, maybe not to you guys but it is for me.
For some reason the concept behind this game really interests me. I think it will give us new spin on the genre. I like a game that makes you think.
I'm now a contributer!
J/K LOL it reminds me of I Spy black vs white. interesting concept of game but lacks luster!
