Really? A public poll? First of all I can predict the result without a poll and secondly what does community preferences have to do with necessary performance changes? This is something that TFP feels they need to do to greatly improve performance and stability-- especially with vehicles. We are getting closer to the finalized version. Once the game goes gold there is no forgiveness for unstable worlds where you fall through not fast enough loading chunks or your vehicle just disappears or because 8 players are riding away from each other in 8 different directions the server crashes. The days of justifying poor performance and glitchy terrain with the time honored phrase of "It's Alpha" are coming to an end. So TFP has chosen a benchmark that they can be sure stability and performance are going to be rock solid for up to 8 players. It's not because they think 64 sq km is better than 314 sq km but were afraid to ask the players so they snuck it in without our say so...
Exactly like those servers can edit the maximum number of players. Yes.
Many servers have had to either remove vehicles or limit the battery size to keep the speed down to a level that keeps the game stable. You can probably increase the map size to what its been with the caveat that you may need to remove vehicles or limit their speed just as before.
Technically, corners were added...
No one really needs to debate it at all. Whether you are for it or against it is immaterial. It is the reality. People can try and compare other games and give their opinions as to why the cut is too drastic all day long but the people who actually know the code and know the limits have chosen the size that works best. There is no reason why the supported size couldn't be enlarged as the game goes through beta and through optimizations a larger size with good stability becomes possible-- just as the number of supported players could well increase.
Welcome to early access folks where you get to experience ALL the ups and downs of the development process. If nothing else at least you can say that you remember having played on a 10k radius map.
