I'm not sure what's causing imy issues. I recently started my first ever Legendary campaign. (Yes, boo me, I know, git gud and all that.) All jokes aside, I've noticed a significant performance drop since starting this campaign. I'm now getting both pre and post battle freezes of up to 5 seconds, as well as having a general increase in response time from button clicks. Loading times seem to be unaffected, but maybe I haven't been paying close enough attention.
End turn times are roughly the same but the transition to a new turn will now take several seconds while audio plays with a frozen screen. Has anyone else experienced anything like this?
