As follows from the description
It should be noted that NVIDIA created this job 17 days ago. In other words, after the release of Quake 2 RTX. So under the words "the project we know and love" is not Quake 2.
There are two older games that can really benefit from ray tracing effects are Unreal and Doom 3. At the time, Doom 3 got cutting edge technology with realistic shadows and fully dynamic lighting, so it could get even better with RTX. On the other hand, Unreal was one of the first games to seriously raise the bar for first-person shooter graphics, and it would also be interesting to see ray-traced lighting in it too.
Unfortunately, there is no further information about upcoming re-releases of classic PC games that will receive ray tracing. Let's hope NVIDIA reveals more details about their next RTX-enabled remaster soon.
