Greetings,
We have been hard at work upgrading various systems that MW2 rely on. This is to reduce problems going forwards as well as reducing the few rare but severe problems that a few of our users have encountered.
So, both the default and iterative branches have now received updates. If you opt in to the iterative beta branch (right click MW2 in Steam and select the betas tab, opt in to "iterative"), you will receive a fairly big update.
This will move to the default branch as well within a few days.
As always, we value your feedback and comments as we continue work on MW2.
Have a great weekend!
Best regards,
Daniel
