[Linux] Inquiry on resources not being released

[aemee]

Description

The games I have tried seems to be minimized/paused but vram doesnt seem to be released.
Most times, vram actually increased by about ~200-500MB immediately after suspending.
Gpu utilization does go down though, fluctuating between 10-30%.

To Reproduce

Steps to reproduce the behavior:

1. Open system monitor
2. Run game
3. Suspend via nyrna flatpak
4. See increase of vram in system monitor

Expected behavior

A reduction in used vram like what I have seen on a windows machine.

System Information

• OS: Bazzite
  • Desktop Environment (if on Linux): KDE6
• Nyrna Flatpak Version 2.27.1

Application or game affected

The Walking Dead, PEAK, via steam.
Hogwarts Legacy, via heroic.
All of them are detected as wine64-preloader.

Logs

Log too long to paste here so uploading it instead.
For this, TWD was suspended.

Additional context

I already had wmctrl and xdotool on my system but just in case, I manually layered them on my bazzite image and retried but still got the same results.

Also tried using cli to toggle, same results but no logs in terminal due to a 'flatpak sandboxing' related message.

The way the different operating systems handle suspended processes is for sure different, but in neither case is it expected to free the used RAM or VRAM.

That might be possible for Linux in the future, but not at the moment; see the FAQ on the README as well as #248.

Will have to clarify that I meant a reduction in used resources instead of freeing them up, bad wording on my part.
As my experience with nyrna started on a windows machine where I saw a decrease in used ram and vram, I was confused when on linux they actually stayed the same or increased instead.

Noted on the os handling things differently as well as # 248, thank you.

Reduced/freed basically same concept (if partial/complete), but I see your meaning. If we could implement even a partial reduction of resource usage during suspend that would indeed be nice. :)
