Windows 11 and RTX 3060

Hi, I recently upgraded to Windows 11. I use TechPowerUp GPU-Z to monitor the GPU usage. I have found with Windows 11 if I open any other application, example Chrome or Edge, there is an automatic allocation of 50% of the GPU usage to the new app. Prior to opening Chrome, for example, the GPU is rendering at about 98%. When I open Chrome, even without browesing the GPU usage drops to 48%
Does anyone know how to fix this? It didn't happen with Windows 10.

I wish I could give you more definitive information, but I remember a discussion that drew a distinction between "allocation" and usage. As I remember it, allocation is something like reserving memory in advance "if it needs it". It's not actually using it. Is DAZ running slowly when you open another app? I think you can check some of this out in display settings within Windows settings.
allocation is just the VRAM, his GPU is rendering. thats something else. I would try to disable hardware acceleration in your browsers. if that helps you found the problem.
Thanks,
There is a turn off hardware ecceleration, when available button so I turned it off. also all other setting like use AI etc. Please see attached. Just renerding screen shot is other apps not active. Dip in GPU load was using Chrome to change settings. Increase was when I closed Chrome. Second screen shot was using paint to copy the window.
Basically, didn't fix the issue.
Two things: Ignore the performance section of Task Manager. In task manager, on the details page, add the column GPU Memory usage. Run a render and see how memory gets allocated to dazstudio.exe.
Two. You can easily just test this. Reboot, do not launch chrome. Launch Daz. Run a render that you know will take 10+ minutes. Note the actual time. Launch Chrome. Go to Youtube and start a video. Then stop it and cose the youtube tab but leave chrome running. Run the render in Daz again. Compare the times.
If this is enabled, try disabling it: https://www.howtogeek.com/756935/how-to-enable-hardware-accelerated-gpu-scheduling-in-windows-11/
You can also add 'apps' in Advanced Graphics settings and set a 'Default GPU' - I've not tested what happens if you have one using your Main GPU and another set to your shared-graphics both running at the same time: https://techwiser.com/set-default-graphics-on-windows-11/
And, depending on your GPU manufacturer, you may have an 'app' that came with your main card / CPU / PC - that may also allow you to tweak 'what is using what'
Thanks,
The Task Master adding GPU columns wasn't something I was aware could be done. It gaving interesting results. The GPU memry usage in Task Master remained consistent, using of not using Chrome.So I watched an online movie using Chrome and the image took 2 Hr 36 m to render. I then changed the camera angle started another render, Chrome closed and left it over night and it rendered in half the time.
A certain amount of CPU is required to keep the GPU fed with information. I find it's around 25% of total CPU capacity on my machine is needed to keep the 12Gb RTX3060 working at 100% capacity. If your CPU is over 50% capacity when rendering this (as my previous machine's CPU was when feeding a 6Gb GTX 1060) then the CPU availability for other process may be reduced and that has a knock on for the rendering speed. As my machine is not online, I've never streamed at the same time as rendered so can't tell the effect.

Thanks, currently, 18% of CPU is being used by Studio, 6,925,812 od GPU and it's taking more than ten minutes to just display a print screen for an online (Chrome browser) to display the actualy print screen page. I think I need to roll back, Windows 11 is not working for me. Sorry, now 15 minutes, Windows 10 was several seconds.
I don't see any mention of your CPU or RAM specs?
Perhaps you should look at what combination of tasks are throttling your CPU/GPU usage before making slash and burn decisions.
Do you mean this?
Device name DESKTOP
Processor 12th Gen Intel(R) Core(TM) i7-12700 (2.10 GHz)
Installed RAM 32.0 GB (31.8 GB usable)
Graphics card NVIDIA GeForce RTX 3060 (12 GB)
Storage 234 GB of 4.55 TB used
Device ID I don't think I should provide this
Product ID I don't think I should provide this

Experience Windows Feature Experience Pack 1000.26100.304.0
Honestly looks like your system should be able to cope. The only possibility is that the RAM is not 3x the GPU VRAM meaning you might not be able to fill up the GPU to capacity. I have the same GPU, a 13th gen i5-13600K, and 64 Gb RAM with no issues, and use Win11. I had similar sorts of slowdown on my 2014 dated Xeon ex-work machine when I had 16Gb of RAM and a 6Gb GTX1060 GPU. I was amazed at how it speeded up when I added another 8 Gb RAM to take system RAM to 24Gb. The fact RAM was less than 3x GPU VRAM seemed to be throttling it at the time.
Apart from mentioning that, I fear I've reached the limit of my possible suggestions.

Thanks Richard
Since you specifically mentioned the browsers, if you haven't already done so, try setting your browsers privacy settings to strictly disable tracking scripts. That might help. Otherwise, when you first start your browser, it could trigger around 20 tracking scripts to all try running at the same time. Some of them can take a long time to load if coded poorly. I have seen that occur before and pretty much everything on the computer froze for more than five minutes. Combine that with rendering, might very well choke the pipelines in your system.
