I can try and give you couple of hints for you to try:Those are: Spartanovka, Apartments, Comissars House and Elevator.
All others just crash after ~1 second of gameplay / when choosing class.
Anyone can give a solution? That's annoying.
(Changed language to English - won't help)
What are you system specs and what settings are you running the game at? Sounds like you could be running out of memory.
I have the same issues - with 4GB of RAM.
I presume that the people who have 3 GB or more RAM and are still crashing are running a 32 bit OS. In that case, you are limited to 2 GB of memory for the game no matter how much RAM you have. So, in that case here are a few things to try -
Nah, I'm on Windows 7, I just have a crappy gfx card and a mediocre CPU.
If you right click on My Computer in the start menu and then select properties, it will tell you whether you are running a 32 bit or 64 bit version of Windows 7 under 'System type'
I presume that the people who have 3 GB or more RAM and are still crashing are running a 32 bit OS.
1. Make sure you don't set the game to use 'Ultra' textures. The game shouldn't allow you to set Ultra textures if you are running a 32 bit OS just for this reason. However, if for some reason your INIs didn't get properly updated, or if you are manually setting ultra textures through the INI, make sure you don't go over 'High'
2. Make sure you are not forcing texture resolution or MSAA through the drivers (like Nvidia control panel), as that will use up more memory
3. During gameplay open up your Windows task manager and check how much memory the game is using versus other processes. If you find processes/applications that are eating up a lot of memory that don't necessarily need to run during gameplay, you can close those applications. Browsers are usual suspects.
So it seems whatever has been done to optimise in the several patches since beta, it has actually worked!
