Extreme FPS drops on Golmud Railway

Hi, after the latest update I’m experiencing extreme FPS drops on Golmud Railway, to the point where playing objectives as infantry is pretty painful.

I asked other players on the server as well, and they’re dealing with the exact same issue, even though many of us have solid hardware setups.

Please fix this as soon as possible so the game is actually playable again… The map itself is really cool, which makes it even more frustrating that we can’t properly enjoy it.
