CPU Behavior

More than 2 cores or more than 2 logical processors? 

My system always seems to use only two cores / four processors.  With exception of a few ripples at load time, the rest are "bored".

Core is a core.  App doesn't care if it's physical or logical.  Your task manager graph looks expected.

I thought all except sound ran on one core? 🤷🏻‍♂️

Again, that's what most people believes because they don't see the graph moving majority of the time until the task assigned to other cores happen.  I just ran this test in DCS and you can see Core 7 and 9 were doing nothing.  Then I pressed F11 and started moving around the map really fast and those two showed activity.  Again, without SDK, I'm only speculating but my guess is those are related to preloading terrain.

Has anyone tried disabling Hyperthreading?

I keep it off just because I only use DCS and two other sims. Tried to turn it on but can't see any benefit, my cpu is about 6° cooler with HT off.

Some feedback from me: disabled the GPU scheduling and got the same CPU results. Load got distributed across all cores again, with one being used more than others.

Perhaps its due to i7 10750H being a mobile processor? Also maximal clock for this processor is 2.6GHz (5 GHz with boost). If I am correct: ED tried to pin to a single core, but OS/CPU decided otherwise.

Hey All,

This is a snapshot of the Persia map flying in the Huey.  The Huey is typically the lowest load on my GPU, and notice that it is only running at 49%.  Both cores are getting hammered and very often I see spiking to 100%.  Both cores are always running at 4.606 GHz when I check them.

The FPS was very steady with no stuttering.  I do not know how close my PC is to CPU saturation running that mission, which is just flying to the west coast from Ras Al Khaimah and then back again.

Hi @stormrider,

I wish to apologize and to thank you.

I was very skeptical (as software developer working actually in IT) about disabling Hyperthreading and at the same time was a lazy to go to BIOS multiple times and make measurements.

Meanwhile I have extended my grafana dashboard to also collect nvidia internal performance metrics (nvidia_exporter).

With hyper-threading enabled:

- GPU usage up to 50 %

- Power usage 50-60W

- CPU usage low (as before)

- FPS in multiplayer 24-55 FPS

With hyperthreading disabled:

- GPU usage is above 90% (close to 100%)

- Power usage 100W

- CPU usage is higher than before (there is still juice left)

- FPS 60-70, and much more stable!

There must some conflict between:

- DCS itself

- WIndows scheduler

- Implementation of hyperthreading

Furthermore I believe this affects the server side as well.

I think I will order Ultrawide, since my test show that RTX 2070 Super can drive WQHD easily.

Thank you for sharing your results.

Hey all,

I noticed some usually stuttering, then I noticed the below.  This was taken on the Nevada map A-10C-2.

I have a feeling that If I had left the game running it would have crashed.  I had restart my PC to get this to reset as every time I re-entered the game it was the same.

 

This is how it should look.

I guess it is just not a perfect world...
