If it were simply about graphics, Minecraft and Fortnite wouldn't be where they are. Besides, the Xbox Series S has two things going for it
- It has a scaler that is pretty decent that will upscale the signal to 4K
- As the generation proceeds, more technologies will emerge that will help the XSS like Direct ML.
All in all, it'll be fine in the long run.
As a side note, I really do hope that The Initative's game is the
third party Perfect Dark game. A reboot with high end cinematics in that world would be dope.
