Unplayable lagg in co-op missions

Hello, I downloaded faforever today, because I enjoy playing the campaign missions in supreme commander forged alliance. On every missions I tried to play on, I came across unplayable lagg. I never had this kind of issue in this game. Are the faforever co-op missions not optimized, or is this normal?

Currently Supcom has an issue with the latest NVIDIA driver upgrade which is kinda buggy. Search the forum for more information on that. Long story short, the current "fix" is to reinstall a previous NVIDIA driver.

@Amygdala I see! Thank you
