CPU use hitting 100% or very close

[osakran]

I'm having an issue with CPU use. I play Destiny 2 and I usually have discord and 1 or 2 chrome tabs open. My CPU use hits about 100% and my mouse will start stuttering in game. I imagine this is because it can't process the mouse because it's overloaded. I had an issue last week where I moved my components to a new case and the LED disconnected hit my back up HDD, sparked and shut my PC down. The HDD was dead but ever since then I've been noticing this issue. I'm sure it was already there and I'm just paranoid and thinking this spark screwed up my CPU. I feel like I had the same amount of things open tho and I wasn't experiencing this before. I'm running a 1080ti i5 6600k @4.3 and 16gb of RAM. I'm running a 1440p monitor at 165hrz.

Quite possible that the spark might be slowly taking out your other components. It's also possible that your system, running off Windows 10 has suffered a memory leak. While idling, are you seeing high CPU/memory/HDD usage? If so you can try a repair install and see if that changes anything.

Ofc you will need to make sure your BIOS is up to date prior to the repair install. You forgot to include the PSU's mare and model and the(full) rest of your system's specs.

I did the heaven benchmark again for the GPU and I got the same results before the spark. I ran geek bench and got results that we're a little over average on the list. I checked my SSD's and they seem fine, I checked them for errors with the tools and the use is 0% for d and 10 and up activity for c drive. I'm just wondering if what I'm doing should be causing so much CPU use or if that's normal? Like I said I'm running destiny 2 maxed out at 1440p, a few tabs of chrome and discord and the blizzard launcher.

Destiny 2 has had issues with i5's. There's a new update that's supposed to fix the 100%usage and stuttering.

Its not just Destiny 2.

100% cpu use "may" be normal. just kill chrome and blizzard launcher off. Anything that is not usable, kill it off. and give a screenshot of task manager performance monitor maybe

I was just reading other threads and some people say that 100% CPU usage is good while gaming because it shows that the entire processor is being used and there is no bottleneck. Other responses disagreed, is there any truth to that? Is there a difference between usage and the load that it can actually handle?

Ideally cpu usage should be 50-70% usage, gpu should be 60-80% usage at best. If either one is hitting 100% usage, it's going to cause fps throttling as soon as the demands go above what the components can handle.

Say your toon is running next to a wall during a battle scene and cpu is 100%. Then the bullets start flying in your direction, each bullet hitting the wall. Every single one of those partials flying around, chips from the wall left by the bullets is affected by physX. You just put a theoretical 120% usage on the cpu. Since that can't happen, you just lost 20% fps instead and went from 60fps to 45fps. And that's simple for physX to handle. Try a good napalm strafe run with its huge fireball explosions. You just went from 60fps to 20fps because the cpu can't do more than 100%usage.

The thing is though I don't experience FPS drop it runs beautifully while it's at 100% usage I'm just wondering if this is normal and I'm getting different opinions. Some people say it's normal and that you want the CPU to be 100% utilized and other people are saying it isn't.

 

[Karadjgne]

Afaik, it's not good to run 100%cpu usage. Not in a game anyways. That's max power usage, max heat output and absolutely no room for anything else or you start loosing fps, screen jitters, mouse hesitation etc. A game like skyrim, for instance, is single thread heavy that only uses 1-2 threads (vanilla game), so how it'd utilize 100% cpu is beyond me unless it was run on a dual core.

And are you sure you aren't the victim of fps drop? At 100% you might be getting 100fps, but on a stronger cpu or yours with higher OC levels, at 70% usage it would see 130fps and still play smoothly.

Imho, if you are seeing 100%, the cpu is being throttled, either by high cpu bound settings or lowered gpu settings on a strong gpu.

 

[osakran]

I don't know then when I play PUBG the CPU is around 75-80%. Maybe its just Destiny 2 being a hog. Either way I dont know how to make it go down any and my GPU and CPU benchmarks are the same as before I had that spark so it must have always been like this. I guess ill just live with it and obsess about it lol.

 

[osakran]

I think the issue from reading a lot of threads is that the i5 6600k just isn't enough for 1440p 165hrz gaming and I need to upgrade it. People are saying its going to 100% because it's being maxed out trying to run at those settings.

 

[Karadjgne]

There's 2 basic types of games nowadays, those that use less than 4 threads and those that use more. In games that use more, like destiny 2, pubg, BF1, Witcher 3 etc, you'll find that the i5 (pre 8th gen) suffers fps loss and higher cpu usage. It's threads are simply packed, forcing the cpu to prioritize and necessary code just gets traffic jammed.

What do you think about the 8700k I might just buy that and sell my 6600k
