Hah of course. Have you seen video of MrWhoIsTheBoss and Markus Brownee about 'how tech companies are lying to you'? www youtube com/watch?v=JstGCPsj9wg 'Up to' is exactly one of the tactics. I wouldn't expect that from Valve.
Valve now admits that 4K/60 fps graphics are not always realistic with its new gaming system. After Steam Machine reviews exposed performance limitations, the company adjusted its marketing. The hardware's high price makes 1080p/1440p visuals not as appealing compared to PS5 consoles.
