100% cpu usage 100% in AC4

[Effenbach]

hey , so my cpu usage is constantly at 100% in Assassins creed black flag - which causes stuttering all the time

 

im running a i7 2700k

and a r9 290x (which is only using 30%)

 

have anyone else experience something similar ? - and maybe even found some sort of solution

 

 

[Levent]

its like that in most of nvidia gameworks games not sure about solution since I never bothered to play the game.

[bydus]

Had the same issue with i5-4690k all cpus 100% and quite sure the rest of the people with i5 had that as well. But you have i7 and not sure why, i upgraded to i7-4790k and my cpu is around 80% on all cores and threads. Game is garbage in terms of optimization, maybe re-installing the game will help..

Some ignorance about Nvidia Gameworks one again.

 

I've played many games with Nvidia gameworks that have great optimisation and many that have poor optimisation. It has nothing to do with gameworks, stop spouting bullshit. AC4 is not very well optimised in the first place and any gameworks features can be disabled and it still runs like shit.

Name one since they started using even more tessellation for no visual pay off, which screws over their own customers in non Maxwell users.

 

BTW "good optimization" means that if a game can do 1080p on the PS4 it is doing 4k or 4xSSAA on the PC. It doesn't mean it can do 1080p with some garbage, blurry proprietary AA that isn't even as good as MSAA and only runs decent on a  970/980.

 

What "good optimization" looks like? See Alien Isolation, Tomb Raider, the new Sniper Elite. What are those? AMD games. They all will run 4k, or 4k 4 downsampling on a high end single gpu card.

 

Nvidia Game Works is such a pile of crap that owners of cards like GTX 770's (which MURDER the consoles) are being forced to turn off or down tessellation in their garbage games. Witcher 3 is currently running at high settings (not ultra) at less than 30 FPS at 1080p on a GTX 980 and I7 4790 per Polish press, when the game runs at 1080p 30 FPS on the PS4 which is less than a 7850 desktop GPU, has a 1.6 ghz CPU with only 6 cores available on the SDK AND has the WRONG ram for cpu (high latency). Nvidia Game Works needs to be slammed by all media. It is not open source, is opposed to everything PC Gaming is supposed to be about and is making our games WORSE, and not better. Why isn't it slammed? Because these laughable tech sites have advertising deals with Nvidia, sponsorships, and are afraid to say anything negative, or they will get blacklisted from early looks at cards, Nvidia games, by what is referred to as the "video card mafia" (Nvidia) in the tech world by the people who work on things like Steam OS. Tech sites and Nvidia are as big a joke as Game review sites like IGN and large developers. 

 

Laughable sites like Tom's Hardware which is owned by a media group and not Tom anymore, refused to even run an article for a long time on the GTX 970 memory issues. The one person that called out Game Works was a contributor to FORBES, which makes Forbes a more reliable site for non biased BS than "tech review sites".

 

 

BTW? I have this setting in Catalyst and my R9 290 will annihilate a GTX 970 at 1440p. Just because I can bypass the absolute BS, doesn't mean it is a good thing. Nvidia is simply trying to push mediocre cards as high end (GTX 970), sell unneeded SLI setups for 1080p/1440p, and cripple a competitor (which could retaliate and do the same BS which would be even worse) by sabotaging our games.

Then explain to me why with my 4670k and a GTX770 and running AC4 at near max setting my cpu only reaches 79% max then having no problems in large fights either?  The games fine it could be other factors like over heating or memory problems and since the OP has a R9 290x it just might be an AMD problem

You're so ignorant. If a game is unoptimised due to poor implementation of gameworks does not mean it was Nvidia's fault.

OP has issues unrelated. I have a friend who has a HD 6950 and 3770 that ran this game medium-high 60fps.

AMD evolved games run great. Nvidia games run like crap. AMD games scale like they should with AA, resolution. Nvidia games don't. The problem is tessellation and Nvidia pressuring, paying the devs to use it on everything even when they specifically say they do not want to pre release, like CDPR did.

CDPR Balázs Török: Yes, we have tessellation currently for landscape and view of the water in our rendering pipeline. We have made ​​some tests in which we have applied tessellation to other objects, but that has not brought the desired result. And actually we need for our objects are not really tessellation. This only increases the overhead, so we use tessellation only for the scenery and the water and leave them with everything else away.

 

PCGH: Yes, we have already found in some other games that tessellation for example, with the depiction of characters makes a mediocre impression and also requires a lot of power.

 

CDPR Balázs Török: Yes, exactly. And there are actually many problems with tessellation. In is rarely spoken. Only a few publications revolve around the difficulties that arise when tessellation is transferred to meshes, but this is very problematic. So it is better to use tessellation only if it thus really gained a huge advantage or technique constitutes a clearly visible difference.

 

BTW this is not a new trick.

The major selling points of Game Works is optimized games. We are getting the opposite. Period. As far as the effects? They can't even get hairworks to run on ANY setup well in these games. The sub 30 fps 1080p GTX 980 Witcher 3 demo shown to Polish press was not even running hair works lol. 

[PerfectTemplar]

 

Recent demo shown @ 1080p with a 980 was 60fps. Also, hair works runs without any performance impact in FC4. Tessellation is not a Nvidia gameworks feature btw it's a DX11 feature so Nvidia have nothing to do with that.

False. Polish press said it had drops under 30 from multiple sources, which I posted in another Witcher 3 thread. Also any Nvidia game where a GTX 770 is listed along with a R9 290 as being equal is ONLY possible with tessellation that the game makers did not want to implement in the first place, which is proven by CDPR trashing tessellation on their assets long before release. Here is another "Nvidia" Game where it did not get the full Game Works treatment (Evolve). The GTX 970 gets absolutely slaughtered by a R9 290 at 1440p and even beat at 1080p. The GTX 980 gets beat as well. This is also Sweclockers who is actually trusted as far as benchmarks. The GTX 970 is simply not a 1440p 60 FPS card and not close to being a good 4k card. We saw the same thing happen in Shadows of Mordor which is also a "Nvidia" title but did not get the tessellation treatment. The 980 you have? IS a good card. It is also behind a reference 290x (which sucked compared to aftermarkets) at 1440p. 

 

The only way you can get a GTX 770 close to a R9 290 is tessellation. Period. In Nvidia games where they do not sabotage performance with it, the AMD cards are ahead at 1440p/4k. You can leave tessellation on in Witcher 3, but you would be an idiot to do it. You should be running it at 1440p via Nvidia DSR or native. It will look miles better and TXAA is a blurry mess. You have a GTX 980. It is a 1440p card. It belongs nowhere near 1080p.

Might want to put your tin foil hat on. I am not an Nvidia fanboy nor have anything against AMD. Whilst I do believe some of their cards use too much power the 290 has always been better than the 770 and any system requirements that compare them are inaccurate, they do not represent real world performance. If a game has better performance with a 770 than a 290 it doesn't mean nvidia sabotaged it. How ridiculous to think that nvidia sabotage games... Also, I don't use TXAA because as you said, it is a blurry mess. When was this, the latest demo btw? They released a vid of it going 60fps and I didn't notice any drops, and yes fps drops are noticeable in youtube videos.

"Tin foil hat"? Buddy we can turn off tessellation on both cards. Both Nvidia card owners and AMD card owners already know this. People with 770's are being force to do this to avoid stuttering at 1080p with console assets which is a joke. We see zero visual upgrade in these photo realistic games with a ton of overhead leaving tessellation on or full in a Nvidia Game Works game. 

 

I posted links of CDPR saying that tessellation can cause problems on good assets, that media was silent on the problems (Nvidia advertising and potential blacklisting for negative press). What more do you want? On Nvidia's own optimization guide to Far Cry 4 on release day, they said the tree tessellation setting screws up the shadows on trees LOL.

 

http://www.geforce.com/whats-new/guides/far-cry-4-graphics-performance-and-tweaking-guide

"Note how the shadows are affected by the geometric detail added by tessellation. Were this a normal map or bump map added by the Texture Quality setting, the shadow would remain unaffected, lying flatly across the tree's surface as it does in the 'Off' image."

 

Tessellation off, with bump mapping. Tree looks like a tree. Shadows are correct. BTW these are pictures directly from Nvidia's site.

Tessellation On. Tree distorted, shadows distorted, for no visual pay off whatsoever and a performance hit that has no reason to exist. They can do this with as many textures as they want, and at least Far Cry  4 gave us the option. It was also added the LAST DAY OF RELEASE. This was Nvidia pressuring or forcing the dev to put something in to put their card ahead on benchmarks lol.

 

Bumpmapping has much less overhead and does not screw up the shadows. It is SUPERIOR which much less of a performance hit. You lose 3 FPS on a GTX 980 with tree tessellation. You lose more on a last gen Nvidia card like a 770/780/780ti and even more on an AMD card. Game devs stopped using tons of tessellation for a reason. It was a ghetto solution for BAD, flat, cartoon textures to make them appear more real. Our assets simply do not need it anymore, and they look WORSE than bump mapping lol.

hey , so my cpu usage is constantly at 100% in Assassins creed black flag - which causes stuttering all the time

im running a i7 2700k

and a r9 290x (which is only using 30%)

have anyone else experience something similar ? - and maybe even found some sort of solution

Does sandy bridge still use PCI-E 2?

R9 290x is a PCI-E 3 based GPU right?

Am i right?

[randy hutajulu]

I had an i7 2600k before my curent CPU

Does sandy bridge mobo still use PCI-E 2?

R9 290x is a PCI-E 3 based GPU right?

Am i right?

[SkilledRebuilds]

Doesn't mean anything.

I had run AC:BF + FC4 on my 290 and had 90-100% GPU usage on my 2600K in both games. <small dips into the 90% GPU usage on BlackFlag (prob due to the engine,.. 61fps limits)

Just peaking of my use, knowing that the game CAN run efficiently.

[randy hutajulu]

Ouuww.. I didnt know that 290 can be used on PCIe 2.

That was my problem when i bought my 780. It didnt work on PCIe 2

[SkilledRebuilds]

Ouuww.. I didnt know that 290 can be used on PCIe 2.

They are both (780/290) backwards compatible.

 

If your 780 didn't work, you did something else.... sorry to say but it's true, I have seen 780's myself running perfectly fine with maximum GPU usage on PCIE 2.0 16x

 

By default it works on PCIE 2.0 lanes just fine.

Mine didn't work. Hahaha.. I don't know why.

But the bright side is. Bow i'm using 4770 with z87 board.

Ahahaha... Sorry. That was autotext.

I don't even remember what i wanna type lol

[potatoes_28]

for anyone looking for the solution in 2021, i have found that if you open the game and once its open open task manager you can stop ubisoft connect and ubisoft connect webcore, that will stop the 100 percent usage on cpu 1.
