Why Battlefield 4 lags in smoke near building in map Siege of shanghai?

[Tadziunia]

Hello guys, recently upgraded my ram, to 2X8gb kingston hyper x fury black 1866mhz, because my old ram died and only 4gb simple 1333mhz patriot ram left, battlefield 4 lagged with 4gb ram, so i dicided to put 16, yea low fps and drops disappeared, but i noticed that my frame rate drops a lot in area near that central building, i get like 20fps at that spot on ultra msaa x4 1080p with my GTX 770 OC and i7 2600k 4.6ghz, in other place i get like 60-80fps+ no problem but there are some areas even though there is nothing happening i get low frame rate, strange thing, gpu usage 99% all the time at that spot and some other areas, it's strange am running windows 10, with latest drivers.

You run it on ultra 4xMSAA on your mid-range card and expect no framedrops? I guess that is your main problem.

Well if the building is down, no one gets gets a good frame rate around it. I go from a solid 60 and above to low 40's.

It's a relatively demanding part of that map once the building has collapsed. Also, what @Majestic said.

it's before falling, there is one entry to the building from sea side and other from road, i get low frame rate near road and bridge

i get low fps near building from road  side near bridge, i can move mouse to other spot and i get like 70+fps, i move mouse bad to that spot there is nothing happening only some smoke and get like 20-25fps

That's simply how it is; your PC isn't functioning abnormally.

that's really strange, i hadn't that problem earlier, that's really strange, GTX 770 isn't so weak can get easy 60-80+fps in other maps, but once there is some smoke it's eats a lot of fps, by the way, that's happening while building isn't colapsed yet

Every map varies from one another as well varying degrees within a single map. I think you just have unrealistic expectations from your 770.

 

There are much more taxing games than BF4, but it is still demanding on mid-tier hardware.

If your gpu usage is at 99% then its just a part of the game, and not your pc running abnormally.

 

If there was a drop in gpu usage, then that would be a problem, but now all you can do is, back off on the aa, when you play on that map...

smoke is hard to render. E.g I also get noticable framdrops on my laptop playing bfbc2 and a smoke grenade going off. It is probably just the way the frostbite engine handels smoke

Displaying smoke is a lot more demanding than it looks...

Dice should delete that smoke at all, there are two places in that map, that's issue with performance, that smoke, don't really do anything important in that map, if that would be deleted i won't get lower 60FPS never, Am agree with you!

they COULD have an option to turn it off... nah, it's just a 110$ game, why bother

that terible smoke is also in second assault dlc, in Firestorm map as i seen before, you can have 80fps the most , but once you turn to that useless smoke it's like 20, maybe you seen it, dunno i don't have dlc at all, so don't care, but i didn't know that such uselles thing can hit performance so hard, i had tu turn MSAA X4 to off, now i get 90-130fps, but once i get to that spot near building i get as low as40fps, not terible but still very noticible drop. agh f*** it.... still prefer bf3 instead of 4

[Sauron]

still prefer bf3 instead of 4

 

And I prefer 1942 to both of them by a country mile

Levolution will always cause FPS drops... 

 

I'd suggest going on servers that don't allow Levolution on those maps (can't disable the game mechanic, but can mod the server well to prevent people from doing it)
