Before the patch I had frames of 50<60 and ping of 130<600. When the ping was bad, it made me seasick, but the game was playable. Crash To Desktop was rare - three in two-thousand games.

Spent 15 hours downloading the patch ( :( ) and have played two games since. The first was normal. The second had major packet losses, CTD, told me the server was temporarily unavailable, after thirty-seconds it allowed me to log back in, and - shockingly - we won! Frames and Ping were as before patch, but I no longer get seasick.

The upside is that I that the packet loss is severe enough that I no longer get seasick; instead of jumping back and forth in little jerks, my tank makes big jumps and long pauses.

I don't think this is playable.

Interestingly, the packet loss continued (for thirty-seconds) after I disconnected from server and alt-tabbed into the forum.
