Hello,
i have couple questions regarding my CPU, cpu utilization. the sim I only drive in is Iracing. prior to the new update I believe Iracing optimized or run on only 1 core. now it utilizes 2 cores. my Q'S
Is it normal to run at 100% on the 2 cores? the GPU utilize at 80% . is this normal? would you call the bottleneck my cpu? or is there no bottleneck here, everything is operating normal?
See images for specs and temps data.
also how can I control the fans on my CPU? on my GPU i can go to Precision X and set from there, but CPU ?
4790k at 4.6 on Hyper 212 air cooler. Asus Z97 Pro gamer Motherboard, running triples at 3840x1080
thank you

core use is actually pretty spread out.

sure 4 & 7 are at 100%, but you left out that 3 is at 85%, 5 is at 90%, and the others are 51%, 46%, 62%, and 53%...

software isn't perfect, sure you're averaging 73% overall, but that doesn't mean every core is going to be at 73%... and it certainly doesn't mean that the game is only using 2 cores.

also if you have the fans plugged into the motherboard you should be able to control them with your motherboards utility program. Head to Asus's site and download and install it.

your rig is running normal from what I can see.
 
Yes I have the fans plug in to movie fans socket next to cpu . I have a question. I want to upgrade to AIO. However my case an Antec gaming case has a 10 inch build in top fan and a 8 inch back top fan. What can I do?

Custom mount the water cooling, remove some fans, buy a new case
 
Ya no . New case out of question. It's a sick gamer case. Maybe remove top fan. Thank you for the feedback

Sometimes mods are needed, but you just answered your question in the most feasible way for you lol
 
Well I knew that would be an option but maybe the pc gurus have a wiser option. Is there another way to control cpu fans? I deleted AI suites. Nothing but headache. Did overclocking through bios

I would try and deactivate Hyper Threading for that game in particular and see if it increases the performance. Thread usage is all over the place, it shouldn't be like that.
 
isnt HT what gives me more hertz? like boost? if turn off would my pc run slower hertz?

Hyper Threading are threads of a processor, your CPU has 4 cores/8 threads, this has nothing to do with the speed of the CPU.

sorry,
so what will it do by turn it off?

By turning HT off your CPU will use only 4 threads instead of 8, it seems sometimes it performs better with games using less threads.
 
Looking at cpu utilization and trying to conclude anything about software threads is tricky, because operating system + cpu balance lightweight software threads across hardware threads in parallel but also move execution of heavy software threads across cores, round robin style, to manage heat distribution. The result is a "soup" that is hard to decipher.
Best we can do is to say the game uses one heavy rendering thread (DX11 style) and multiple lightweight threads (physics, audio, networking, etc.) and the cpu usage you see is the best you can get - it's not you and your system, it's the game
 
ya thats what i thought. so my systems under load or while playing looks, okay? what about temps? on previous reply i send a link to 4 AIO coolers which one would best fit for my system?

I wouldn't bother with that. I ran multiple tests on my i7 4790K with and w/o HT on. All results are within margin of error. It used to make a difference many years ago, but these days just keep it on. Even temps and power consumption are roughly the same.
 
ic cool, thank you. i was not sure why I would turn of HT, people buy CPU that have that option.

Max 57 celsius in that game, with more cpu usage in some other game I guess you'd max somewhere in 60'ies ... I'd say that's pretty good for haswell @4.6 on air
 
Again your thread usage seems all over the place, listed in your own log. Simply trying to disable HT for more possible performance wouldn't hurt, you can reactivate it after if it's not helping. Generally I'm not recommending deactivating it - I'm just talking about one game here, Iracing.
