NVIDIA has been struggling in recent years to find use cases for their graphics cards. That's why they're pushing towards raytracing, because rasterization has hit its limit and people no longer need to upgrade their GPU for that (they tried pushing towards 8k resolution, but that's complete BS for screens outside of cinemas). However, most people don't care about having better reflections and indirect lighting in their games, so they're struggling to get anywhere in the gaming market. Now NVIDIA is moving into other markets for their cards that don't involve gamers, and they're just left as an afterthought.

I don't think that this will ever change again. Games like DOTA, Fortnite and Minecraft are hugely popular, and they don't need raytracing at all.

I personally tried going towards fluid simulations for games, because those also need a ton of GPU resources if calculated at runtime (that was the topic of my Master's thesis). However, there have barely been any games featuring dynamic water. It's apparently not interesting enough to design games around.
