I think this latest patch is better for my old machine. Everything off I had a solid 60 fps. With most advanced graphics on I was down to 22. My rig is pushing 8 years old. No Disco's last night for the 4 hours I played. I feel it is an improvement for me as I would seem to disco a few times before.
That map also I believe had a problem up north in the past and I would disco more often at the northern most bases.
All in all I give it
