i5 4590 bottlenecking gtx 1070?

jwright201 · Apr 17, 2017

Hello, I have noticed that after I upgraded my gpu from a 970 to a 1070, my fps barely improved in GTA 5 in 1080p. I'm not really sure if this is happening in other games bc this is really the only game I have at the moment (don't ask why). So I decided to run afterburner in the background while using the GTA 5 benchmark to see if i had a cpu bottleneck. After the benchmark was finished, I noticed the gpu had a usage percentage of about 70-80%, and even 60% in some areas. I thought that it must have to be a cpu bottleneck then! But I went and checked the cpu utilization and it wasn't even 100%. it was about 80% most of the time. So what is the problem with this? Wouldn't the cpu be pinned at 100 if it were bottlenecking the gpu? Would upgrading to an i7 4790 (non k bc I only have a h97 mobo) make a difference? Or maybe upgrade to a r5 1600 bc that would end up only being a tad more than a 4790 itself?

Anything can bottleneck nearly anything else with the right mix of application and settings.

That said, GTA5 specifically is a poorly optimized title CPU-wise. Your best bet in this case would be overclocking if your h110 board supports it.

I'm going to assume that you're gaming at 1080p which in GTA V is heavily CPU bound. A GTX 1070 probably won't have too much issue even at ultra settings. As the poster said above, GTA V is poorly optimized for CPU usage and I agree with what he said about trying to overclock. I'd also try other games and see what it does as 1 game doesn't give a clear picture of system performance.

Doesn't sound like your CPU is holding back the 1070 however change the graphic settings (low to med to high), if your FPS doesn't change then the CPU is your issue.

Also the i5-4590 is a 1150 socket while the H110 motherboard is a 1151 socket so either you put typed in the wrong CPU or MB.

sadly it doesn't support overclocking, and also its a h97i, my bad. I will test other games and update

Alright I will try that and update.

ah yes it's actually a h97 motherboard, my bad. I recently built a system with an h110 motherboard for someone so I guess I got them mixed up.

Ok, try different settings and record the FPS (min/max), if it doesn't change then your CPU is the problem. If the CPU is the issue then I'd look at either a i7 or even Xeon CPU.

Ok benched it with lowest settings at 1080p. Most of the time it was pinned at 60 fps (vsync turned off so idk why it wouldn't show the frames above that) but there were definitely same major stutters in the benchmark. According to msi afterburner, the gpu was at a comical 30% utilization, and the cpu still hovered in the 80% area. Definitely seems to be a cpu bottleneck, but I'm going to bench another game or two just to be sure

Hmm, so if the game vsync is turned off then check Nvidia Control Panel>Manage 3D settings > Vertical sync > Make sure this is set to: "Use the 3D application setting" or turn it OFF.

Look for high disk activity at times it stutters. Often, loading new data in open-world games can cause a hold-up.

Otherwise, CPU seems fine IMO if it's staying at 60 FPS.

@dudeman509, agreed as long as the OP's monitor is 60hz.

turned it to off, but I am currently downloading doom. My hard drive is pretty slow though, so it may be a few hours until I can give y'all the deets

WildCard999 · Apr 17, 2017

That's fine, finish downloading and make sure nothing else is running in the background that doesn't need to be running then retest.

doom averaged over 100 fps, 80-90% on gpu, 70-80% on cpu. I found a really good deal on a 1440p 144hz monitor, so I may just upgrade to that from my 1080p 60hz monitor and call it a day bc that will mostly eliminate cpu bound-ness
