ray tracing.

[Квазар]

will there be a full version of ray tracing?

It’s a vr game so the game doesn’t have Ray tracing because you need a lot of fps for vr games and Ray tracing is to intensive for vr games

Source 2 (the game engine used) has no ray tracing support.

I think most fairly new computer gaming hardware can handle it honestly (but I'll admit that probably wasn't the case when HL:A was initially released). I ran Half-Life: Alyx with maxed out graphics and it looked beautiful in my Valve Index at 144 hz, played on an RTX 3070.

And plenty of other headsets are only 90 hz, which should be easier on a GPU.

And we have a new round of next-gen GPUs from AMD and NVIDIA that probably blow my RTX 3070 out of the water.

If my RTX 3070 can max it out at 144 hz, I could probably run it at 90 hz with maxed graphics and ray tracing on my 3070. And probably RTX 3080 users, and anyone on an RTX 4000 series card could run it at 144 hz with ray tracing and no problems, assuming they're also on a Valve Index.

How is the updated Portal game running ray tracing then?

It's not Source that 'runs' RTX. NVIDIA captured the game as it loaded using USD (Universal Scene Description) as the exported file format, which is then imported into NVIDIA Omniverse, that converts the static, baked lightning into fully dynamic lightning. Lots of steps later, after the 'mod' is finished, NVIDIA injects some APIs in the game through the use of DLLs (e.g. NRD.dll - NVIDIA's Real-Time Denoiser, nvngx_dlss.dll - NVIDIA's DLSS, etc.), creates a new game executable, exports the 'mod', and the assets back to USD files, which are then interpreted by the game properly as if they were regular Source-compatible assets.

The renderer was also replaced with a 64-bit Vulkan renderer that enables the use of RTX, real-time lightning, glass refraction, and so much more. Source is just reading the files and plopping them in place of the old ones, while NVIDIA's own renderer does all the work.


Source doesn't support RTX, and it never will. It's way too outdated, and it doesn't have support for the technologies that make ray tracing possible. It's still a very capable engine, considering the graphics still hold up 18 years since HL2 was released.

maybe in 20 years. technology isn't quite ready to have literally everything having real time raytracing.
maybe look into what raytracing really is before asking stupid questions.

You could not have picked a worse example of why RTX is a bad idea in a lot of games especially VR. Portal RTX is destroying GFX cards even 4090's. The performance is terrible.

Well, Valve is forward looking. May as well be the pioneer to add RTX to VR for the 0.01% of the cutting edge rig gamers

Indeed. I feel horrible for all the RTX 30-Series users that thought they could play this and have decent performance. I think RTX Remix is a terrible idea. Portal RTX is a great example why you can't take a 2000s-era game engine and think you can hack together new features. NVIDIA can be very experienced with what they do, but this isn't it.
