Laggy sandbox, GPU memory dropping

[Skull Lady]

It was running fine before until today. When I clicked x on a part, it freezes for few sec then continue. I don’t know why.
I have Titan xp gpu. I don’t understand Why it does that? I was just building ropes over the bridge.

In this case it's the gpu-usage which is dropping, cause there is a cpu-bound calculation and therefore you gpu has nothing to do.
Those thing happen and it's about the game engine and not your hardware.

CPU utilization didn't spike either, but yes, it's clear that the GPU was waiting on something.

That's cause not the whole cpu is fully utilized. The game is simply waiting that a certain operation is performed, which might not even fully utilize one core , especially if the data that is needed is not in the cache of the cpu.

The thread in question could already have been pegging a logical core at 100% utilization, but if the game is waiting on data that's not in the CPU's cache, it would be a memory or storage bottleneck, not a CPU one. All that can be convincingly inferred from the single glance at task manager in the video is that GPU utilization falls, without GPU memory utilization changing much (not loading or evicting significant assets) and it's therefore unlikely to be a GPU limitation.

Well, sorry for long awaited response. I was occupied somewhere so I found this https://www.pcgamer.com/try-turning...source=facebook&utm_campaign=buffer_pcgamerfb

I turned off game bar then went back. It seem little better but I don’t understand why GPU had to take burden of memory instead CPU.

Closing other programs, tools, addons might help. Having a powerful CPU with fast cores, might help, but there will be the point your PC is fast, everything is optimized, and you still have sometimes those lags. And many hints and tips relating to shooters or other action-games do not really work.

but I don’t understand why GPU had to take burden of memory instead CPU.

ignore the memory-part...it's mainly the utilization of CPU and GPU

Operations on the GPU-side are highly parallelized....those on the CPU-side are not.
If your GPU can't handle the game well, you have just less frames.
But, on the CPU things sometimes can't be done at the same time, cause the next operation might be depend from that now.
( It depens on the game engine and how things are done)
And planet zoo is a complex game. Objects are not only something that is visible, like in many other games, they influence other parts (traversable area and so on)
If there is a delay on the CPU-side (for whatever circumstances....even with the best hardware) , the game can’t progress....and your GPU has to wait and this is that freeze

Very simplified: the GPU is the lawnmower. If the grass is higher it might run slower. The CPU is the person that operates the lawnmower and has sometimes a bit hassle to turn around on one end.

My pc specs.
i5-8600k @3.60hz
Titan xp collectors edition
16 gb ram

so I should get better CPU?

No...cause it's likely that your game-experience would be the same.
Your specs are fine.

A simply question, do you have this problem very often, sometimes or rarely ?
And do you have this problem in a specific (maybe bigger) park or even in a small park?

 

[Skull Lady]

it happened after i made groups of ropes, I was building the bridge. Havent notice it on franchise park yet.

If in your current project many objects are invovled...that might be a reason and you have reached the limites of the game and not your hardware ;-)
And yes, I'm very certain that nobody is able to run the game with a decent frame rate in really a high detailed park that uses the whole map.

Man, I have plans for this zoo. So many things I had in my mind would be amazing. It would be jurassic but aztec ruins style

I just did task manager, it works. no freezes

i'm at you at 8 to 11 fps in my zoo with only 900 animals and 23 breeds .... will that improve?

 

[Firestar97]

I really hope we will get a fix for this. The Game is really slow when I'm in my Main-Zoo even though there were way more Guests in the Past and I didn't had this Problem back then. I experienced freezing in my other Zoos but this seems to be at least way rarer since the last Update

Edit: the mentioned Zoos are in Franchise-Mode

 

[tnnuy]

I have the zoo very simple and with little things and I still have problems with fps ..

this zoo before version 1.2.4 can't even play, now it has improved, but the fps have gotten worse since version 1.2.3 ... I played well in this zoo in version 1.2.2

CPU - AMD R7 1700
GPU - GTX 1070 8GBS
RAM- 16 GBS 3200 GHZ
M.2 Samguns EVO 500 GBs

Edit : forgot to say i play in FRANCHISE mode
5,000 people visiting my zoo

Not a hardware nut but guests are known to make zoos lag. Try and limit guest counts in the settings to lower.

Something for me changed a couple of days ago.. I would run at 99% GPU which required power throttling to keep the game from crashing but I was able to do it. Then a couple of days ago the GPU was used less(50 to 80%)... CPU usage was about the same (8 core/16 thread) with all cores reporting about half usage.I would get lag when pathing... or adding barriers to habitat, pretty much anything requiring calculation. Both the CPU and GPU would drop to 0 utilization before quickly going back to normal. Not sure what is triggering that but its very recent.

Yeah the update we got when the DLC were released seems to have caused a bit of issues in terms of lag. Pausing the game while placing barrier etc should remove the lag (it does on my end) Otherwise, perhaps submit your findings in a Bug Tracker.

I also think the same, after buying the artic dlc and the one from south america my game got much worse and slow
