Describe your issue / feature…

This is more of a question than a real issue, although I would love to see Hyprland become more optimized than it currently is, if that is a possibility.
I have noticed for a while that Hyprland seems to use a lot of VRAM. Currently it’s using around 800MB of VRAM for me, which for reference is enough memory to store 13 uncompressed 16-bit per channel 4k images, meanwhile I only have a 1440p HDR monitor and a 1080p SDR monitor.

Moving my cursor between windows also seems to spike GPU usage pretty high, probably due to the drop shadow effect.

I am no graphics engineer, but if the window manager gets too recourse intensive will that not impair performance of games and other apps?

Would love an explanation for where Hyprland needs / uses the GPU memory.

Much of the VRAM is shared buffers from your apps.

Anyways, for the gpu usage, that’s normal. The desktop isn’t free.

Exactly, you should stop worrying so much. Hyprland is really light. Run an fps benchmark in a game or whatever.

Idk i find the opposite its one of the lighter ones out there.. I get increased performance vs others.

A lot of people misunderstand VRAM reporting in Linux.(Even % can be a bit different then windows reporting) The number they’re seeing is often total VRAM allocated by the total graphics stack, not what Hyprland itself is actively consuming alone…

Hyprland is just the compositor. The reported VRAM usage can include fraebuffers, textures, monitor buffers, wallpapers, blur effects, animations, GPU caches, applications, apps, browsers, and driver allocations. Espeically on multi monitor setups, especially at high resolutions and faster refresh rates, those buffers add up super quick.

I think the betetr question would be “What is the performance impact?” In my experience though, Hyprland is one of the lighter desktop environments/compositors available. I generally see better responsiveness and game performance compared to heavier desktop environments.

There’s also major differences between systems. driver behavior, monitor count, resolution, refresh rate, widgets, bars, effects, wallpapers, GPU architecture, Ram speed, and CPU scheduling can all affect what gets reported. That’s why the most meaningful comparison is usually actual benchmark results and frame times like varxy mentioned above rather than a single VRAM number shown by a monitoring tool.
