Maybe I'm just one of the unlucky ones. I've been pretty diligent about it, my issues are existing without mods on a pretty high end system (I think). 1080ti/4790k/16gb...I can't run battles smoothly over 400 max, and even then in sieges it drops to the 40's on high end hardware. Using a standard HD with slow read/write speeds, but this is the only game I know of that actually relies on your HD to serve as alternate RAM thanks to the memory leaks.
I found out Reshade conflicts heavily with the game right now and was causing some serious issues, which hasn't been reported yet. The only mods I'm running now are the alternate launcher, Tyni's fixes, community patch, Fix holding, auto blocker, fast dialogue, and Z unit fixes. That's it. No conflicts that I'm aware of. Removing them all and trying performance in sieges and battles has been the same...just really choppy/low FPS or crashing. Sometimes it seems OK for a couple days, then a patch is released, and it seems to conflict with those mods (I updated regularly).
