This week I finished a re-run of WoL and HotS campaigns. I now started the LotV campaign and I immediately notice that the game feels laggy.
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

running sc2 as an admin gave me almost x2 more fps
|
I've been having random FPS drops as well. I played a ladder game today on 30-40 for a good portion of it (would normally be in the 100s). Thought it was just my system crapping out
|
I double checked my claim. And indeed - I have 60 fps in WoL and HotS while 40 fps in LotV campaign and co-op (I do not dare to try out custom games).
Wtf happened to SC2? Why it lags all of a sudden?

I will try that out ASAP. brb in 1min
Edit: Didn't help

same here, random fps drops since 4.0.0. tons of bugs and lags.

Do you have vsync off? Because mine was actually acting like it was on even if it was turned off in the options. I just forced it off from nvidia control panel to resolve it.

I actually have more fps after 4.0 oO about 20-30 fps more on avg, but I have only checked it with arcades and not campaign or ladder.

Tbh I play with Intel graphics card and so in this control panel there are only 2 options for vsync: use application settings, or use driver settings (doesn't say what it does). Changing it doesn't seem to help.
Still, the most interesting part is that WoL and HotS campaign I can play with my usual fps that I had all this year. That's so strange...

I think you are right.
Since the only option in Intel control center is to use "application settings",+ Show Spoiler + I have no way of testing if it's 100% true.
But I did try enabling and disabling it in SC2 options. And it changes NOTHING for me. I clearly remember experiencing fps drops in the past when I tried to turn it on. So I guess you are right - it is on even if it's switched off.
Lucky me I guess. Blizzard just create this new bug and I just so happen to use Intel :/
I wonder if someone could test it if it's really true and therefore a bug? Then there would be hope that Blizzard could fix it.

They might have fired their performance testing engineer for SC2

Hey I ran into similar after a windows update, was able to run the game on med - high without a problem and then suddenly dropped to constant 25 -26 fps on LOWEST
What fixed it for me is right click the SC 2 icon and under the compatibility tab Check to disable the full screen optimization thingy.
Another thing you can try is to disable if you haven't yet the Xbox gaming DVR bullcrap like this :support.steampowered.com
Hope this helps

same here - everything on low, had decent fps in wol and hots. cant play coop or 2v2 cuz it stutters so hard when there are many units on screen.

Every major patch (and some minor ones) since 2010 there are people making threads like this and almost all of the time the performance hasn't actually changed at all
The performance of the game changes a lot depending on what you're doing and is partially linked to the CPU performance of the slowest PC in the game, that can give a lot of unexpected results or particularly laggy single games. If anyone is hitting below about 30fps then everyone in the game will start to see weird performance including stuttering and playing slower than real time and this is a common thing to experience in co-op + endgame 2v2 battles since a lot of people run the game that poorly.

Windows vsyncs everything on win10 and 8 unless you play in exclusive fullscreen (not windowed fullscreen) and windows 7 does as well unless you use certain desktop themes
For the "always at 60fps" stuff i'd have to assume that you weren't monitoring performance very well - far more powerful systems drop below "60fps" in co-op and high unit count 2v2 games, even on FPS optimal settings; they always have.
There could be a lot of legit reasons for your system having performance or maybe this is one of the patches that does affect FPS, you're just not gonna get 60+ at all times by fixing it if there is a problem. One thing that you can look at is running your older replays, they'll load a 3.x version of the game if they were played on it so the game will run as it did in that patch.

^ i mostly play an arcade game with the same ~150 people. previously, i could always notice a clear difference in fps between patches - i think around 3.0 was the first time that the fps was just cut by about 20% for me. there were a bunch of other patches that also reduces the fps by another 5-10% each. however, 4.0 was the first time that i actually got a fps increase from a blizz patch. i went from about 140-150 to 155-180, which was quite a noticable increase. considerting that i mostly play one arcade with the same ~150 people and rack up about 40 games per week, i am pretty sure that any fps changes are only caused by the patches and have nothing to do with the connections of the people i have been playing with for years.

You can benchmark it by comparing new and old replays since loading an older replay loads the version of the game that it was made on

Can't you click on that "on" text to make vsync off? I don't know about intel graphics but try to google how to disable vsync for it.

Thanks. Now I know that I was right.
I checked a replay from this patch and a replay from the same co-op mission that was played more than a half year ago (patch 3.14)
Today's replay was with 40-53 fps while that old replay was with solid 60 fps (my max set). Both of which were first few minutes of replay - didn't see a point to watch any further.
I know that ~10-15 fps drop doesn't sound like much, but on a 60Hz monitor, it sure can be felt.
I didn't double or triple check with other older replays because I'm 100% convinced that I'm right.
I actually am not very happy about being right.... this time..
RIP co-op. At least I can still play Arcade I guess...

FPS I get in this game is very funny. My specs:
Core i5-2400 3.40 GHz
8Gb RAM
GTX 960 960 4 Gb VRAM
HDD
Win10 x64
Yeah, it's pretty low range rig, but game is 2010 itself, so that shouldn't be a big problem, right?
I have custom graphic settings, but average is medium, and there's no way I can get steady 60 in 2v2, 3v3 or coop. 4v4 sometimes going slideshow. In 3v3s can drop below 30s.
Recently I followed Hybrid Settings thread and tried to set blob shadows with high shaders. I got simple blob shadows working fine, it even improved visibility, but it just ate additional 10 FPS... I checked 3v3 replay, in big fight with normal medium shadows I get 30-40 FPS, with blob ones I get 20. What the hell? Thankfully at least 1v1 mostly sits on smooth 60.
Anyone got any tips on what to tweak to get a bit more FPS outta this game? Anything I've tried already didn't work so well...

It's CPU limited so there's not much that you can do short of buying a much faster CPU which means new motherboard and RAM, even the fastest struggle at those sorts of times but they're a lot better than what you currently have
