Returning player. Hadn't played since some time last year. Fired it back up again a couple of days ago. Ran into the following issue:
75% of the time when I launch the game, from the initial countdown page and through the splash videos, right up to and into the agent select screen, the game runs at about 5 FPS. 25% of the time when I launch the game, I get no issues whatsoever.
I'm running a Ryzen 7 3700X OC'd to ~4.3GHz, 32GBs DDR4 RAM @3600, an EVGA XC GAMING 2080 Super, game running from a Samsung 980 Pro M.2 on a PCIe x4 bus, latest updates for all software components. I'm running the game in 4k @120HZ. When it starts without issues, it runs like a dream.
I've tried killing all background processes (that I can), killed the Ubisoft overlay, played with various graphics settings; nothing seems to make a difference. When this occurs, my resource utilization is minimal. Temps are nominal. Hardware seems to be running fine. I cannot find the root cause, and it's driving me mad.
Has anyone run into similar issues, and found a fix? I've Googled it some, but the nature of the issue is such that even carefully tailored search syntax returns generic results about buying a better GFX card, and updating your drivers. Any help would be greatly appreciated.
