I've played C:S on my old notebook when i released this grid and it was only playable up to 100k.
Besides that i don't think it's the size of the city that matters - it's more about the whole network.

good work. have you tested in a fully populated city? i have trouble getting anything above 60k on my own but with the help of some pretty popular road mods.

Thanks for your comment. Doesn't worked so well for me, so i build this one. Since TM:PE and NExt were released i'm not using these grids anymore.

going to test this now, looks great. thanks
