ESO Core usage? Only seems to utilize 1 core out of 6

Tapio75

I have 6 core processor and ESO seems only use 1 of them. I have checked affinity on task manager to see if all cores are checked and they are. Power plan is Hi performance, I checked bios to disable power saving on processor plus optimized all processor function in BIOS too.

What is the problem?

MMOs are not really made for high end PCs , they are made for average.

Very small chance they would spend the time/resources making the game do so.

I'm not sure about this --- but I think they have to deliberately restrict it to use only one processor. I think Windows 8 will use everything it has for a program unless specifically told not to. If that is right, it shouldn't be hard to use more cores.

@Tapio75‌, I also have a 6 core processor and have seen the same behavior. Unfortunately ESO does not take advantage of multiple threads. Or if it does, it is far too dependent on one thread.

If I am in a busy town my GPU usage drops as well as my frame rates. Always when this occurs the one thread is pegged at a 100% while my other 11 virtual cores (6 cores hyper threaded) sit almost at idle.

I have found that reducing draw distance seems to have the biggest effect in reducing this. But, this also causes more pop-in so I leave the draw distance at 100 and just accept it.

A good way to verify is to go to a solo instanced area and you likely will see less CPU bottle necking.

You can't force parallelism on a linear program.

Tbh last night at Cyrodiil I saw all 8 threads been at 90%. (i7 4820K overclocked at 5Ghz)
After awhile kaboom. Out of memory error. First time seeing that since played the game.....

(I use MSI AB to monitor the system performance).

This is not exactly true. You can take a single threaded program and make it run faster by using parallel processing. Even if the application does not know about it, the compiler, operating system, and processor does.

Also, ESO is a multi-threaded program, not a linear program.

ESO does use quite a few threads, which will often be assigned across multiple cores. The main thread seems to consume a whole CPU core by itself and this is what people are seeing when they say that it uses only one core. The other threads, which are active when needed, will use the other cores in amounts relative to what they need to do.

In this manner, the CPU utilization is not balanced, but that does not mean that it is only using one core. It is using more than one core, but it is just using one of the cores a lot more than the rest.

Still terrible multi-core and no 64-bit support is really pretty sad in a 2014 title.

Point at me titles that support 64bit, and came out this year. Especially MMOs.

I can't point out single brand of ramen noodles that has any nutritional value.

It doesn't make a particular brand fit for human consumption.

64-bit or not is not the issue. Failure to balance the load over several cores is a big issue, though. Pegging one core at 100% with other cores more or less idle is inexcusably bad software design.

True. While 64-bit would allow more than ~3.7gb of RAM use the real problem with the awful micro-stuttering performance on modern systems is the poor core balancing.

I bet this game would perform better on a massively overclocked Core 2 Duo.

Can confirm my intel C2Duo overclocked to 3.4ghz (stock is 2.4ghz) plays the game worse then my i5 at 3.2ghz.

Different ram and mother board though, the ram clock on the C2D is much less then my i5 but the same amount of ram (8gb).

May be worth testing with an i3 overclocked using the same ram but not worth purchasing another processor just to test.

2/4 cores for me. - i5 3570k

What makes me wonder, If ESO was intended for New Consoles, which have 8-core AMD CPU's, How is ESO going to run on a console when you are effectively cutting off ~75% of its cpu performance?

I'm guessing, not well.

With the same way other games run like a dog on PC while flies on PS4.

The low level API is different on PS4 & Xbox than on PC.
I won't be surprised if the PS4 version will run as good if not better at 1080p than my i7 4820K at 5Ghz and the GTX780Ti at 1293.

Also you should not compare the FX Piledrive with Jaguar, as someone shouldn't compare a Core2Quad with an i5

Same issue here but it only seems to affect loading of the character select screen after that I see all cores in use. Very odd.

Uses all 8 cores on mine.

Check that the .ini file is set for multi-threading and if you have Nvidia make sure that is multi-threading as well.

I dont know if AMD has an option for that.

I have the logitech ARX app on my ipad.

I see core usage in real time.

Pretty even on my system. I rarely see a core go over 70% with the exception of being on a zone screen. Then the even cores flatline and the odd cores max out.

Just disable Multithreading in BIOS and use "Easytoolz" to force the game to use all physical cores. That works fine.
You dont need Multithreading for gaming.
