Did they change somethign with the graphics in the latest patch?

Did they change something in the way how the graphics work in the latest patch? I nave had this issue before. Tonight, two maps were almost unplayable due to the speed slowing down to a crawl. Both maps had effects on the ground as a modifier.

Yeah. Firewalls make the game unplayable sometimes. I tried fortress firewall and it's even worse. 4k to 5k lag spikes and it has been like that all day. Sometimes there is rubberbanding, but usually, the game just go slow motion.

Something is wrong, but I don't know if it's server side, on my end, or if the graphics messed up something and mske the game slow down.
