Heavy FPS drops in scenario with high amount of units

Hi guys,

just wanted to know if it's usual to have heavy FPS issues with high amount of units. For example I'm playing with a neighboring against one insaine AI on a big map. After about 20 minutes the military and economy score of the insaine AI is over 300.000. Than our both systems collapse nearly at the same time (we're talking over TS) so the FPS sinks permanently below 10 and at least near 1 FPS. At this state the game crashes. But far earlier below 15 FPS the game is unplayable. During this process the workload of CPU and GPU sinking together with the FPS count. So with <10 FPS and a insane AI score >300.000 the CPU is on idle state with 1600MHz with no workload and the GPU is nearly idle. Why do they stop working in this process?

First some data from my rig:

Intel Core i7 3770K @ 4,5GHz
16GB DDR3 2400 CL12
EVGA GTX 1070 FTW
game installed on Samsung 850 SSD 500GB

In general I don't believe in unsatisfactoryworkload capacity from my rig for this game cause my neighboring has the same issues with an rig with an Skylake i7 and GTX 1080.

My rig reaches about 85fps on the GPU forced benchmark with the "extreme" graphics profil on DX12. Little worse DX11 and vulkan are working. The CPU forced benchmark is about 45fps on DX 12 with same settings.

So trying to lower the details got no luck to rise the FPS in heavy units scenario. Do anyone has this issues too and knows how to fix it?

If you're playing a multiplayer game with him, have you checked your connection settings? The more data your connection has to handle, the choppier it's going to get if it isn't up to snuff. If it doesn't happen in singleplayer, it's connection. If not, I'd start to look at case flow: Your GPU/CPU might be able to handle those while it's cool, but if it's cooking itself trying to calculate/display everything, it's going to throttle itself to save itself after a while.

I don't know what to tell you. Even at around 4,000 logistics used, my game still flows fantastic in singleplayer, and that's with an R9 280X (Several notches down from your card) and an overclocked FX-4170 (Which I think might actually be below the minimum spec listed).

The last time people reported getting terrible FPS even with high end systems was when fighting lots of Substrate (insane would count) who created lots of drones which killed performance. I thought this had been fixed but perhaps test vs only PHC and see if the same performance issues repeat themselves.

Odd that CPU and GPU usage both go down though, I'd expect CPU usage to go up.

Hi guys!

first thanks for the answers! After my nightshifts I continue with investigating in the frame drop issue described before.

Just started a singleplayer with PHK only and beyond multiplayer activities - and yes it's much better but still available. Started with over 100 fps with 99% GPU workload durable. After ~30min my rig holds 40 fps by about 15000 units score und > 400.000 military and economy score. With substrate insane AI I assume the game would crash at this point with <10fps. However in this PHK only game the CPU/GPU workload dropped to around 40-50% and the CPU started to reduce the frequency at which point I quit the game.

@ RomeoReject

Usual load temperatures CPU ~49°C and GPU ~ 45°C. The CPU is cooled by Alpenföhn Olymp and the GPU by Arctic Cooling Accelero Extreme IV. I'm monitoring many rig real time data with the keyboard internal display from logitech G510. AIDA64 sends all the data to the keyboard display.

So theoretically the temperatures shouldn't cause the issues.

@ Ticktoc

Yes I also expect raising workload by high demands but the opposite occurs. I assume anything prevents further forcing the CPU workload. Maybe any kind of driver overhead or anything like that? Strange issue.... cause at the beginning of any game or in bechmark scenes all works fine.

Just for a few minutes I continued with campaign escalation (didn't finished it yet ). The maps containing partially over 6 enemies some of them substrate. With military and economy scores around 15000-20000 (so lower than any multiplayer game) the massive drop began. Finished the maps with ~20fps by 20-30% CPU/GPU workload.

BUT during switching around DX11 / DX 12 / Vulkan just noticed that vulkan has lower "maximum" FPS than DX 12 though but much more FPS stability and lower CPU usage at all. The CPU is able to hold higher minimum FPS and frequency reductionoccurs significantly later but is still available. Maybe the (however it's called) "game engine" is limiting and has issues with handling such high amount of units?

That is fairly common, had it happen lots of times, I had some missions where the game wouldn't even respond for mins at a time, or finally crash out.

I'm having the same problem as Webster2808. My computer is well above the required specs to play this game. I have all the latest drivers and have followed all the instructions at the Stardock Knowledgebase webpage.

The games plays flawlessly in skirmish for about the first hour. Toward the ending when all bases are pretty much maxed out on units my computer slows down to a crawl, and is unplayable. I've also tried DX11, DX12 and Vulkan. Same results. It usually only happens while on 6 player maps, or more.

Hi there, I am new to the game and have not experienced this until today. I am still finding my way around so tonight I tried a skirmish game against an easy AI just so I could try some different things out without too much hassle from the enemy. I had probably 200 frigates/cruisers and maybe 10-15 dreadnoughts at the entrance to my base after maybe 45 mins to an hour and noticed the game was laggy. FPS was dropping to 30 then 20, it seemed to be really struggling (although GPU usage dropped a bit) so I zoomed right in and out again a few times and things went back to normal, even though the same amount of units were present. From that point on the game ran fine until the end but the lag lasted a good minute or so, seems I am in the lucky minority that it recovered.

Get an AMD.

Is there a vote for the most useless reply? Because this would sweep.

OP: How are your temps doing on that i7 when there's a bunch of stuff on screen? Perhaps try running CPU benchmark and compare it to a GPU benchmark, could help pinpoint the issue. Also, have you tried running it without mGPU enabled, just to see if that makes a difference?

Asynchrnous Shading is only available in AMD, this solves the problem of FPS drop, ie: under load.

I've never had this slow down issue on my system. If anyone with the issue uploaded their save file where it is happening I'd be interested in giving it a go, and saying how it went.

Perhaps I just haven't done big enough games with enough AI to see it.

Well , i have a Full AMD RIG.

Specs:

Fx 8320 in standard factory mode, no overclock.

20 GB Kingston HyperX 1866 RAM

Aourus RX 580 8GB

And the game is installed on a Crucial MX 300 525GB SSD.

So my problems. Installed the game on Win 10 x64 , directx 11/ safe mode = crash in skirmish after 3-10 minutes, dx 12 = same, Vulkan = same.

In last resort i installed a clean Win 7 on my ssd, and tried again. Dx 11 = crash, dx 12 is not avaiable on Win 7, Vulkan = crash . The game only works in SAFE mode, but there are sometimes crashes on certain maps, but at least the game is about 70% playable (it crashed 3 times in 10 games) .

Any opinions ?

I suspect Asynch Shading is not turned on in Ashes and only Async Compute because if it was - Nvidia card users would start freaking out with endless bugs and crashes and you would have a lot of pressure for refunds on your hands.

Any thoughts on that>?

Hm... Not to ask the obvious, but:

You're not overtaxing the system (4K Ultra Settings, stuff like that)?
How's the airflow in the case?
I don't what's going on with Vulkan, but it seems super unstable at the moment, I'd recommend you avoid that.

Nope, im playing Borderless Window mode in FullHD mode, my monitor isnt 4k compatible , the settings are mostly mediocre, the airflow is good, i have more than a dozen fans in the Case, and a liquid cooling system, so that are not a problem too.. And im playing it DX 11 safe mode.. So still not know what a real problem is.

That is odd then. I'll let someone who knows what they're doing take it from here.

The following may be the problem, or at least part of it. Looks like there will be a fix with the next patch.

Well i know the people working on this game really low right now, but i hope to theese fundeamentally bad bugs are gone in some day ( FPS lag, random crashes, etc.)

Well at least the Juggernauts are real meat... ehm.. metalgrinders , i love them , and i want to see where this game is heading. There aren't any good RTS games nowadays besides Ashes.. And after at least 2000 hours, im getting bored of Supreme Commander..
