This is an incredible tech demo. Portal's new facelift is absolutely gorgeous and I've spent minutes just staring at the walls and looking at how the lighting interacts with various materials. If you have an RT-capable graphics card, this is a great excuse to replay Portal again (and really, not much excuse is needed, is it?).

Performance-wise, it runs a lot better than I was expecting. Easy to clear 50fps with a 3090 by turning DLSS to performance mode, and it still looks fantastic at that setting. From the pre-release chatter it sounded like a 4xxx series card would be mandatory, but apparently not!
