for me its as said only one little stutter once every few seconds. sometimes only once every 30 seconds but its still horribly annoying because the game otherwise runs flawlessly at 60fps and 16.6ms frametimes.
this one stutter is a microfreeze and drop below 60fps for a second (just writing this again for blizzard in hope someone sees it and this will be fixed. otherwise despite all the massive downgrades i like the game. if the grass would be higher quality i wouldn’t have anything to complain graphically. the grass though looks really trashy… in the blizzcon demo it looked a million times better!! also unit animations stuttering should be fixed because it feels like their animations run at 30fps looool)
now to answer your questions. this one stutter i have is always there, regardless of what i do… if i don’t move the camera, don’t move the mouse it happens aswell. but more rarely. if i build something or do stuff it happens more often.
i just tried the campaign and i actually was able to start the first prologue mission (before it was instafailed) and this issue wasn’t present in that campaign mission. after than on the second campaign mission this issue started happening, first time when i wanted to build something.
by now (i’m actually very knowledgable about all this stuff, i’m regularly fixing most games to run flawlessly because devs mostly can’t, though this one i wasn’t able to fix with none of my tricks. that said, i know them all, setting a game to a different priority through the registry, setting a game to use large page files, all the nvinspector fixes etc) i’m pretty sure the thread author here is right and it has something to do with cache flashing all the time… its the most logic explanation and thus this is something that is unfixable from our perspective. only the devs can fix this and i hope they will.
to further answer your question, on scrolling the map i don’t have any stutters, its buttersmooth even with the biggest maps fully revealed. the only stutter i have is the one freeze every few seconds and it happens regardless of what i do
