Why is my BAR1 Memory always occupied?

[RipperPix00]

I successfully enabled Resizeable Bar a few days ago, but I found that my BAR1 usage is different from everyone else's, my BAR1 is always in a run-out state, even though i'm not running any programs.

My BAR1 usage:

Interesting, I'm observing this too:

• MB: Asrock Z370 Extreme4
• BIOS: L4.21B (CAM support from manufacturer, no additional bios image patching)
• GPU: NVIDIA GeForce RTX 2080 FE
• CPU: Intel Core i7-8086K

Since I'm unsure of the source of that value, it could have a different meaning than what we are attributing to it. Windows' task manager shows a normal vram usage (as well as GPU-Z).

Same issue here.

Anyone figure this out yet?

A quick scroll through the more recent posts in working cards, it might be to do with the driver version. 552.55 is the latest driver i could see that has BAR1 usage low.

Im in the same boat, does it affect performance or is it just a difference in reporting?
