> And so you've just recreated the PC gaming market again.

What's the issue with that?

Really? What’s the issue for not having a known target to optimize for?

That hasn't been a serious issue for 20 years. The overwhelming majority of big games are now being released for PC on day one, the only exceptions being platform exclusives and Rockstar games.

Developers certainly have no problem making PC games.

I can go to a store today and buy a Sony PS5 and know that it will play every game designed it for with the same quality as any other PS5.

Can you say the same about buying any PC? Will that be true for any game you buy for the next five years?

Then the order is on batch level? Say batch1 is committed with a smaller timestamp than batch2, then all messages in batch1 are considered prior/earlier than any message in batch2?

It’s getting late and I’m not 100% confident I’m sure what you’re asking, but I believe the answer to your question is yes. When you produce a message/batch you get back offsets for each message you produced. If you produce again after receiving that acknowledgement, the next set of offsets you receive are guaranteed to be larger than any of the offsets you received from your previous request.
