When you go to the task manager, you can see how much RAM you're using.

Is there any way to find out how much VRAM you are using?

W7 64 bit here. ATI Radeon HD 4890 card

EDIT:

GPU-Z and HWiNFO don't work.

ATI provides a tool too, but it keeps displaying 35MB in use. No matter what programs and games are open.

PerfStudio works, but is to advanced for everyday use, it is for analysing system recources while running a game. Has a built-in debugger and everything.

Note: As it stands it appears this is only valid for Nvidia cards, GPU-Z does not appear to be able to get this information on Ati cards.

You can see how much video memory is in use on any reasonably new Nvidia graphics card using GPU-z, which you can get from http://www.techpowerup.com/gpuz/

For example my card shows:

Note the "Memory Used" field. I believe this should be available on almost all current cards, though I don't have an Ati card to check.

You can use HWiNFO to determine the percentage of video RAM in use. It shows up in the sensor readings as "GPU Memory Load" or "GPU Memory Utilization". HWiNFO does not work as confirmed by the original question's author.

For advanced users with NVIDIA cards, you can also try the official NVIDIA PerfKit software, which "gives you access to low-level performance counters inside the driver and hardware counters inside the GPU itself".

For advanced users with ATI cards, you can also try the official GPU PerfStudio software, which includes "a Frame Profiler that allows you to identify per draw call performance issues at the hardware counter level". This should give you access to the VRAM usage, but alas, I am an NVIDIA user, so I cannot test this for you.

By now, I found out that Process Explorer from SysInternals shows VRAM usage.

Download Process Explorer from this url: https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer

Then drag procecexp application to your desktop. Double click to run it and search for Nvidia in my case and kill the tree. Worked like a charm. Stable Diffusion in my case and the out of memory warning is cleared.
