Constantly crashing...

Switch off multithreading in options. After doing this the game stopped crashing for me. See if it helps you. I was crashing consistently ever since the update.

Same here. Tried dx9 and dx11 with or without multithreading. Game keeps crashing since the 2.6.0 version. I love the new league (with the league stones) but the crashes not so much.

GeForce GT840M if you must know (in an MSI GP60 2PE Leopard) with driver version 378.66.

I have been experiencing crashes doing uber lab since 2.6.0 as well. It sucks, I hope they can fix it soon.

also getting these crashes, both dx9 and dx11 versions of the client, run a GTX970. Can post the rest of my spec's if more information is needed.

Unable for me to finish labirynth - get 40+ tries and game always crashing for me - in 95% of cases in loading screens between locations ,5% was a unexpected errors and crashes in the middle of locations or right after entering izaro chamber(after killing him by someone who carry us)...I tried everything,disabled multithreading,changing dx11 to dx9,going with or without minions,alone and with party,deleting dx11 cache in game folder,trying few graphical options settings -NO RESULTS...I loose all my nervs on it - waiting for patch...
What is curious that my game working good and crashing very rare when play maps,acts1-4 - i can say I can play normally but labirynth is completely unplayable for me...Crash every few loading screens between locations and sometimes even at first doors from aspirant plaza...When I try take a lab carry when I enter a boss room after someone kill izaro I see sometimes a bunch of explosions and game freeze,moving one framerate per some time > then crash . but mostly as I say 95% of crashes are on loading screens between location...
I need ascendary points and cant get it now...

I dont know when problem start exist but its 2.6.0 or 2.6.0d fault...Nothing like this happened ever before when I playing this game(last 2 months)...
