Hello,
i had low gpu usage.
I tried add to app_config - max_concurrent 3 and it worked, it increased usage from 74% to 85-90% and now 2 projects are crunched at the same time, instead of 1, but still not 3.
Gpu usage 85-90% is still not effective, while crunching einstein project, my gpu is at 99% constantly.

Next thing i tried: run two clients using program BoincTasks and i ran to several problems:
-BoincTasks doesn't load app_config, so only one task ran per client, that means i would need 3 clients and than i hopefully could utilize my gpu.
-Tasks got aborted all the sudden, no idea why.
-I don't know if i even ran that second client correctly.

There are almost no guides and i was only get partial information from the forums, which context i don't understand.
How do i get my gpu usage to 99% with this project please ?

Some of these GPUGrid Work Units require a fast CPU to feed the GPU quick enough to enable high GPU utilization. A CPU with high IPC (Instructions per clock) and high clock speed are desirable. Not all GPUGrid Work Units require a fast CPU as the more atoms simulated the longer it takes the GPU to produce a frame and the less dependent it becomes on the CPU. The problem is the smaller atom simulations that have high draw call. For quickest return rate, which is more important to the researchers than utilization, I would run 1 Work Unit per GPU even if the utilization is less than optimal. You can improve your GPU utilization by overclocking your CPU, switching your crunching PC to a non-WDDM Operating system such as Windows XP or Linux.

Okay good to know, thank you.

After i changed cpu utilization to 12,5%, or it should be 13.5% ?
I got 90% GPU usage, even while i am crunching only 1 task at the same time.
So it doesn't seem, you get any advantage from crunching 2 tasks at the same time, especially if GPU usage doesn't matter anyway.
But TDP does, which is the same - 60% max, either i crunch 1, or 2 tasks at the same time, i don't know if there is something else to be done about that here.

You recommend Linux, but Retvari Zoltan says in this topic, that he has only 7-8% cpu usage in Ubuntu 16.04, due swan_sync is not supported there
Ofc there are many distros, i will try some probably.

But gpu utilization is gived by application programming, or it can be something on Nvidia's side i guess and 780 isn't most up to date card.
Probably not much i can do here.

EDIT: God :O, in afterburner, there is a feature - temp limit, i am used from gigabyte oc guru to target temp, which is only preference not a limit, well tdp went up to 6%, will tweak that further.
Ye it increased perfomance, well...

Apparently there is gpu usage preference for this project, it calls "Maximum CPU% for graphics", i would never expect it would be named like that.
I thought, there is no option for controlling gpu usage with this project.
My bad.

I can't OC, because i have cheapest mobo.

Ye i know about unparking cpu cores and disabling power saving features in bios.

My cpu is currenttly constantly running at 3.67 ghz, i can get up to 3.9 ghz with turbo and either eist,c1,c6, or thermal function cause it run at 4.12 ghz tops, which is ackward, but it adds latency and cause inconsistent clocks, it may be worse than run cpu at 3.67 ghz constantly, i don't know.

I will overclock my gpu yet gradually, it is all good now.
Thanks for help btw.
