So I check the fps and I'm surprised that I have 40 fps. I have played through all of WoL and HotS campaign with solid 60 fps (which is my max set), or at least it not once felt laggy.
I did have 1-2 months break from SC2, but before that - I did play SC2 on daily basis for the entire year. Arcades and co-op, always with solid 60 fps.
So now I try out co-op to see if anything changed about that. And yes, I do have 40-45 fps even at the start of co-op just like in LotV campaign. I played 100+ co-op games this year and they were all with 60 fps.
Nothing on my laptop was changed during that break of mine.
However, it is worth noting that my sc2 launch settings have been reset (why?). So no "launch 32bit instead of 64bit" and no "additional command line arguments".
I tried that 32bit option - it changes nothing. I tried to open SC2 through SC2Switcher - it changes nothing. I remember that in the additional command line arguments I had in the past it set to use some directx version, to launch the game windowed version instead of full, and some 3rd command that I don't remember. I highly doubt any of them changed anything since they were there for like forever and I don't even remember why they were.
Hopefully, I can get some answers. Otherwise, I can't play SC2 anymore
