A Half-Life 2 RTX demo is now available for Windows on Steam, kicking off this free modification for Half-Life 2, Valve's classic first-person shooter sequel (which is required). Despite not being listed as a demo, that's what last week's announcement called it, and the description also says it is the "Ravenholm and Nova Proskpekt demo." This project from community-based developer Orbifold Studios leverages NVIDIA's RTX Remix software to enhance the graphics of this 2004 release with all sorts of modern goodness for owners of NVIDIA RTX graphics cards. Here's the recent Announce Trailer along with more details:
The fight for freedom begins anew. Experience the award-winning game that has captivated millions of players worldwide with its immersive story, thrilling combat, and mind-bending physics, fully overhauled with full ray tracing, new hand-crafted, physically based textures, enhanced high-poly models, and updated lighting, all in stunning 4K.
Half-Life 2 RTX is a free DLC for all Half-Life 2 owners developed by Orbifold Studios, a collective of passionate, community-assembled developers behind Half-Life 2: VR, Half-Life 2: Remade Assets, Project 17, and Raising the Bar: Redux.
Half-Life 2 RTX uses the latest version of RTX Remix leveraging new RTX Neural Rendering technologies, cutting-edge full ray tracing, accelerated by NVIDIA DLSS 4 with Multi Frame Generation, and NVIDIA Reflex to bring one of the greatest video games of all time to life in a whole new light.

Most of the comparison shots didn't involve fire and the new version just seemed overly and unnecessarily bright to me. I'm not even trying to say it isn't realistic, using ray/path tracing, I'm sure it is. But as I alluded to in my previous post, it can still be realistic yet maintain the atmosphere by turning down the dimmer switch a little (where appropriate).
Of course it's going to be significantly brighter overall, that's just the reality of having light bounce around properly. Any flashlight that isn't a cheap toy should easily fill an entire room, and a fucking bonfire will illuminate an entire city block... Does anyone really think it was an intentional artistic decision to have a humanoid enemy that is engulfed in flames from head to toe *not* project a large amount of light around it? Don't you think they would have liked that to happen, but just couldn't achieve it 20 years ago?
With that said, there is a brightness slider in the options which I did lower a fair amount, as the default made it look pretty washed out. That doesn't do anything to change the number or placement of light sources, though. Many of those in Ravenholm are industrial floodlights, so...
I love HL2, and I'll be playing through this. I'm not shitting on the game and I even said I'll reserve judgement until I can see it for myself. I was just voicing my preliminary opinion based only on this video. Chill people.
