RTX I/O is going to be a big feature, and games are likely some of the first consumer-facing software that will use it because it is a standard features for the next console generation. And AAA devs already support multiple performance profiles, feature support fallbacks..etc. There's no reason they couldn't have the engine take advantage of RTX I/O when it exists, but otherwise fall back on an emulation layer of sorts. In addition, I suspect the slice of the video game market that has a GPU with RTX I/O capability will also have a NVME SSD. Now, this is niche, but with that slice of the market also being the top-end performance tier, they're still going to be catered to by AAA devs.
