Thanks to everyone!
My fix does nothing with 1.52 and MemSaver = 1 (it just doesn't affect resources created in video memory), and with 'MemSaver = 0' it crashes (at least with my system). I will check this out and see if it's still worth the effort to make any improvements.
Also I think 1.52 can be improved. Memory-savings are better with official fix, but scrolling itself is slower and swapping is more frequent for some reason. I will see why.
BTW, 1.52 has fixed globe view slowness with my system (even with buildings ON). Though, I was suprised that disabled buildings actually disabled "streets" square beneath the city, buildings themselves are still in place.
No matter if my fix remains alive or becomes useless, I'm confident (at least for myself), that top part of official 1.52 improvements were born from this forum posts (including mine). So, it's alive forever, being in Firaxis code. Well, thanks Firaxis
In case I'll see no path to improve it ahead, I will release its source code, perhaps Firaxis will be able to make more improvements looking at it.
I don't think I'll have any payment and 'thanks' from them bearing in mind no contact up to this moment, and they were in much worse situation until 1.52.
So at least you'll get something from them watching my work. I'll get other things, paying off in the long run (including cash / job offers) after releasing that, so please don't think this will be just a sacrifice
Merry Christmas (and Happy New Year) everyone!
