Is this my system or AC Unity?

[r7slayer]

Alright guys, just been playing around in AC Unity and noticed its choppy in places so i decided to look at what my system is doing. You may not be able to see too well from the pic below but the stats are as follow

GPU usage: 67%

GPU Temp: 66 degrees

GPU Mhz: 1031 (max speed is 1150Mhz)

D3D11/FPS is: 42.6 (averages around 45 in busy places such as in the pic)

CPU1: 58%
CPU2: 69%
CPU3: 61%
CPU4: 72%

And as you can see from the stats there is not full utilization, so im asking my self why this is and i cannot understand why. So i'm currently considering it to just be the game with it being poorly optimized? Surely with the cpu not at 100% or near that at any core its not a CPU bottleneck?

Anyway running

i5 3750k 4.4Ghz
290x at 1150Mhz Core and 1500Mhz Mem
Seasonic 750w 80 Plus Gold PSU

System should handle this game fine right?
Cheers guys.

Cheers for the reply guys!

What you got going on there is directx bottleneck.

Hmm i guess that makes sense! Ive seen it in a couple of other games before but they haven't been sub 60FPS so never bothered me much. Just quite annoying to have sub 60FPS but yet more juice left in the tank for the game to use.

Try running the game at 640x480 or some very very low resolution. The CPU cores should max out then.

High Resolution : 1440p - 4 K > GPU Bottleneck
Low Resolution : 1080p or lower > CPU Bottleneck

Simple things you can google about .

When people test gaming CPUs they are run at very low resolutions

I forgot to mention I was running 1080p and I know that higher resolution doesn't require more could grunt just gpu but the doesn't matter in my case. Also I did Google first and got no where which is why I asked other fellow overclockers. But thanks anyways.

To the op, what settings? Ultra textures ideally needs more than 4GB VRAM. utilisation on a single card should be higher though.



No it's not. It's a combination of the AMD driver and the game.

Sorry not at pc right now but im sure textures are only on high and im only on 1080p anyways so not going to be anywhere near 4gb probs just touching 3gb at most.
Also running 1600Mhz on ram 8gb of it at 8-8-8-24 timings. For peeps asking. Im putting it down to a mix of game optimisation and direct x 11 bottleneck for now seems most plausible which I didnt think of at first.

Once again you're going to keep digging aren't you lol.


Also if the OP has a frame limiter on or in fact vsync then the usage won't be representative anyway

Vsync is on but no frame limiter. My problem is I get 40-45 fps in places but not full usage on gpu or CPU.

Eagerly waiting to hear what happens when you turn it off....

Will let you guys knw later tonight still away frm pc. Not sure it will do anything other than let the tearing take control lol

 

[r7slayer]

Well for the people interested i've tested with Vsync off and while it seemed only very little noticeably smoother the usage and FPS remains the same. However i'm getting tearing here and there which is annoying. Vram usage is at 2583Mb so like i said in a previous post not touching no where near 4Gb

Everything is on high with SSAO on 1080p so i would be expecting more than 45 FPS running through the streets. I can't tell if my game is fully updated as i installed through uplay but i'm going to assume it is. So just guess ill have to accept its Direct x and game bottleneck.

edit - turning settings down actually decreases GPU usage, get around 60% on medium, high is mid 70 and very high/ultra seems to top out GPU usage. However FPS dosnt really increase much. I have a 1080p monitor with 120Hz refresh so i expect it to try and at least reach 120FPS
