>The techniques you speak of work with static games
Wrong.
You are mixing up pre-rendered lighting and global illumination.
Realtime GI has been used for well over a decade.
Hell, the STALKER 1 from 2007 has the feature, but it's disabled by default, because it was waaay too heavy for the 128-256MB DX9 cards at the time.
FOX engine games, NieR Automata and Replicant, Death Stranding, even goddamn Elden Ring have non-RT GI. Even stylized shit like Genshin Impact has GI!
Be it with quick bounce or via probes, Global Illumination was already an industry standard by 2010s. Paired with Screen Space Reflections, you can also achieve decent reflections on surface for practically no performance penalty.
Pic related is from an old, oldass OpenGL 4.3 tech demo.
tl;dr: RT is a meme, trying to re-invent a wheel, just to sell you 3000 dollar GPUs.
