From my sources now: The DLSS version shown behind closed doors by the "Nintendo Switch 2" tech demo was 3.1 and not 3.5 as reported or pointed out by Eurogamer.
Ray-Tracing is indeed possible and the RAM memory I was told was 12 GB for the consumer.
Source has been right on some information such as that EA would no longer make the legacy game Fifa for Switch and on previous Direct dates.
