Sometimes, but not always, I get a tiny bit of input lag upon pressing E at the title screen. When it does this, it takes at least twice as long to load the save and plop me in the castle. It does not end there though; battles are a slog to get through, especially with my Mana Bomb strategy. Normally I can use Turbo Mode to hold down E and it runs like double-greased 75 FPS lightning (that is to say, very well). With the lag, it does not even get close to that kind of FPS, going at less than half of the usual FPS for creature sprites to disappear when they die. Menu speeds and walking in realms seems to be fine though…
Like I said, it’s on Steam that this happens; my mobile savefile does not do this whatsoever, and it does not always do so on Steam even then. My guess is that something on Steam is bogging it down, but I could not begin to tell you what I think is doing it.
EDIT: Should probably mention, I recently cleared out my spell gems and artifacts at last, so I know it’s not those. In fact, even with a metric crapton of spell gems (600k essence worth, I had to save up to grind them to gem dust), I still never had this problem until recently, when I got back to S3 to celebrate the KS of Ultimate.
EDIT2: According to the forum list, I posted this in the Siralim Ultimate subforum? Oops…I could have sworn I picked the right one.
