After patch 1.5 my game start to crash when my character leaves the city.
No matter, Whiterun, Windhelm or other. IT'S SO ANNOYING.

And most important i have crash when im trying to leave Whiterun in mission "Battle for Whiterun".

I FOUND SOLUTION if anyone else have similar problem.


SOLVED.

RECIPE: UNINSTALL WARZONES mod, now it goes well.

Disable all your mods, and regenerate your .ini files, and see if that makes a difference.

SOLVED read first post.

What mods were you running before you disabled them? Were they installed manually, via NMM, or SW? I think mods that change the world space can have lasting effects in your save files, even if they've been removed (e.g. RWT 2.0). Are you running via SKSE as well?

Also, worth posting your system specs.

Ive solved that problem it waas caused by WARZONES mod.
Im only removed that mod, so i think it causes a problem by adding
event and npcs to the world space.

Im using NMM, have about 30 mods installed and no conflicts or CTD's.
Im using latest SKSE and launcher from NMM.

My specs are:
Intel quad Q9550, 2.83mhz
8 GB ram, 800mhz ddr2
Geforce Gtx 560

Errm, you told me you disabled all your mods early on and the issue was still happening, then you now say it's fixed due to a particular mod being active?!

Also, polite to thank people who try to help you.

thank you good sire

No worries, glad you got it sorted!
