Most maps like this actually crash before they finish loading. I'm guessing if you already lag on small maps than this will be literally unplayable for you. Feel free to try though, I might be wrong.

Now play 64v64 on this map.

only 60GBP/kg reasonable enough :D

Spring supports maps up to 64x64 without problems, beyond that labels don't work properly. The greater challenge is having enough memory to compile maps of this size. At 22x22 I begin to encounter problems with mapconv

It is perfectly playable. We just had a big game on it:

There wasn't much noticable lag, but we had an unit limit of 75 per player which certainly helped.
