Seems like your OS is responsible for being a lot more frugal with VRAM at idle. On win 10 I'm usually somewhere around 1 gigabyte, give or take a couple hundred megabytes
I think that Windows will have the highest VRAM usage, but Linux with KDE Plasma or Gnome will probably also use more VRAM than 135 MB.
If I open a 3D shooter with outdated but decent graphics then I see 4xx MB of VRAM.
So I can play a fun 3D shooter with less than half of your VRAM usage.
I've seen it up to 3GB (that one on HWiNFO64) as I use the PC overtime for many hours, but its hardly a problem. Never cared really
Can we see the RX7600 on HWiNFO64?
In your case, if you have 24GB of VRAM, then you are never going to see a VRAM shortage.
The most popular GPUs according to the steam hardware survey:
#1 RTX 3060 (has 8GB models)
#2 GTX 1650 (4GB VRAM)
#3 RTX 3060 Ti (has 8GB models)
#4 RTX 3070 (has 8GB models)
#5 RTX 4060 (has 8GB models)
#6 RTX 2060 (has 6GB models)
#7 RTX 4060 Laptop GPU
#8 GTX 1060 (has 6GB and 3GB models)
#9 RTX 3060 Laptop GPU
If you have high VRAM usage you also have more code that can be abused by a hacker.
A codebase that is 7 times larger also has 7 times more vulnerabilities for the same amount of bugs per amount of code.
