Why is my system not running at its potential?

romeodakins · Jun 12, 2013

My cpu is A8-3870k and GPU is 7850. I used monitors and monitored my gpu and cpu usage on this game and both of them aren't even running at near max usage and my game has lag spikes where the fps dips to 30-40fps.

I checked my monitors and for total cpu usage: 61.5% maximum. Gpu utilization: 87% maximum(the actual readings are all 30s, 40s, some 50s percentage. Idk why it's 87%

As you can see, cpu is running at about half of it's power. Also I want to point out on core 0 it is running really intensively with lots of 70s and 80s percent usage at times but all other cores low numbers.

T've seen on youtube people with a 7850 and a crappy amd cpu can run the game at like 60+ fps avg. Is it a game driver issue or something or is there a bottleneck somewhere. I'l upload the readings for cpu and gpu usage as file if you need them.

If vertical syncronization is turned on, it will reduce framerate to 30fps when your system can't keep up the 60 fps. Try disabling vsync in game.

You have an APU. They are not fast enough per core to keep up to a HD7850.

It's off

I know my apu sucks but it's because I upgraded. But should the cpu be decent enough? I don't see any bottlenecking from my monitoring. Also I see an issue. Core 0 is running really intensive at 80-90 percent at times while core 1 2 and 3 are running at 20-40 during the 80-90 percent moments.

Your 3870k will only load 100% in games that support 4 cores CPUs.

romeodakins · Jun 12, 2013

Madn3ss795 :

Ooh, that's helpful. The game I'm running is Warframe. It shows all 4 cores being used though. Core 0 is being used a lot, like 80 percent while core 1 2 and 3 are at 20-40 percent.

This guy on youtube has a 7850 1GB AMD Athlon II X4 640 Processor. I'm pretty sure even my processor is better than that and my 7850 is 2GB and he's running 1080p maxed 85+fps and I'm getting 40-55fps with 30fps dips.

Madn3ss795 · Jun 12, 2013

If you plus the total core usages while you play, you'll realize that it barely passes 200%.

romeodakins · Jun 12, 2013

Madn3ss795 :

Took a sample and adds to 189. What does that tell me?

Madn3ss795 · Jun 12, 2013

It tells that the game you're using to test your system can ultilizes just 2 cores. Small loads on 2 other cores mean the first 2 cores shared a bit of their work with them, or are being used to run background tasks only.

csf60 · Jun 12, 2013

romeodakins :

That game is only able to use 2 cores. If it were able to use 4, your total should sum up to 300-400%

romeodakins · Jun 12, 2013

Here's the log for the monitoring I did
https://www.dropbox.com/s/hp6pt3hp34lot7e/log.CSV

Gpu doesn't seem bad at all, averaging around 40%
Does this mean my cpu is bottlenecking?

Also for my cpu to be truly bottlenecking, does core 0 have to be running at like 95% overall it's in the 70s-low 80s at intensive scenes(where I lag to 30-40fps) I don't get how the people on youtube run this game so good though with crappy processors.

Novuake · Jun 12, 2013

romeodakins :

That is exactly what it means. Very few games support more than 2 cores. The fact that core 0 is near maxed makes the bottleneck clear.

Madn3ss795 · Jun 12, 2013

A screenshot of task manager would be easier to view, you know...

Anyway, yes, your cpu is bottlenecking the 7850 heavily.

romeodakins · Jun 12, 2013

Madn3ss795 :

I'll take one in a few minutes.

romeodakins · Jun 12, 2013

Madn3ss795 :

Took some more pictures
Here's task manager, msi burner for gpu usage, and a monitor program for core usage

This picture shows gpu utilization(which is gpu usage right?) and maximum is 87% which is weird, I didn't see it go that high on msi burner.

I don't understand, shouldn't core 0 and core 1 be running near max? On the task manager, core 0 is working hard but core 1 is working as weak as core 2 and core 3. Core 1 and 2 should be at like 80% right?

romeodakins · Jun 12, 2013

Update, something really funky is going on.

As you can see I'm not even in a game yet, no AIs no cpu intensive things going on here and core 0 is reaching for the sky at almost maxed usage.

Madn3ss795 · Jun 13, 2013

Weird things here. Try to download Process Explorer and use it to see what program is using the CPU in the background.

romeodakins · Jun 13, 2013

Madn3ss795 :

I'll try that. When I check my cpu usage right now all cores are at at very low stable usage so I don't think it's a virus or anything.

romeodakins · Jun 13, 2013

Madn3ss795 :

I used the program here's what showed up.

Madn3ss795 · Jun 13, 2013

Eh if your CPU loads when there's game running then what's wrong?

romeodakins · Jun 13, 2013

Madn3ss795 :

Here's a better image

Game dips to 46 fps(sometimes 30s) and the process Warframex64.exe is using only 35 percent. That's not even close to maxing out the two cores(50 percent). Also if you look at the task manager, core 1 is being used heavily. So does this game only utilize 1 core? Don't get me wrong the game runs fine but I just want to know if my system is running at it's best because on youtube other people run the game way better than me with nearly the same setup.

Madn3ss795 · Jun 13, 2013

Yes it seems like that game can use 1 core only. How's the GPU usage when you play ( use gpuz to know this info )?

romeodakins · Jun 13, 2013

Madn3ss795 :

I used MSI Afterburner and GPU usage barely hits 50% usually in 30-40s. Do you think overclocking my CPU to 3.0ghz to 3.5ghz or higher if needed would help a lot since my cpu is bottlenecking. I want to know if it's worth ocing.

Madn3ss795 · Jun 13, 2013

Are you already using highest graphic options for the game? It doesn't seem to be a cpu/gpu intensive game any at all, thou.

romeodakins · Jun 13, 2013

Madn3ss795 :

Everything maxed. A person on youtube has the Athlon AMD Athlon II X4 640 Processor and gets 85fps+ avg maxed 1080p. I don't know what's wrong with my system/drivers.

Why is my system not running at its potential?
