I posted my message also at cities xl own forum:

beneath my message:
I think I solved the lagging issue. At least it worked for me big time!
I opened the GlobalSettings.cfg file with wordpad
(on my pc located in C:\Program Files (x86)\Focus Home Interactive\Cities XL 2012\Data\Config\)
Search for the phrases:
<!-- Visibility Manager -->
<VisibilityEnabled>2</VisibilityEnabled>
<VisibilityRender>0</VisibilityRender>
and change the 2 into a zero -> <VisibilityEnabled>0</VisibilityEnabled>
Now when you start the game and load a city all objects such as trees and city lights will be only drawn once so no redrawing of objects when you scroll the screen.
Pre-rending objects in the game, so no real time rendering
Search for the phrase: <ProcessEnabled>1</ProcessEnabled> and change the 1 into a zero -><ProcessEnabled>0</ProcessEnabled>
This setting draws all objects (trees, citylights, etc) beforehand so no drawing of objects anymore in the game.
try it out and hopefully this will help you too!
edit: I am trying out all kinds of settings in the GlobalSettings.cfg file here so far some other things I discovered:
I also tried to change the 2 into a 1 -><VisibilityEnabled>1</VisibilityEnabled> It does the same as the zero but I get the feeling that the game runs even smoother.
PS: Feel free to try out different settings yourself what works faster for me doesn't necessarily mean that it's doing the same thing for you, I think it greatly depends on your system.
btw: I also used the the 4 gb patch (only for 64bit systems): http://xlnation.net/content/cxl-4gb-ram ... it-os-only
& increased the poolsize this is also located in the GlobalSettings.cfg file: change <PoolSize>2048</PoolSize> to <PoolSize>4096</PoolSize>
as discussed on this page: http://xlnation.net/content/cxl-2011201 ... mment-4180
Cheers.
