Too high GPU memory usage

Describe the bug

Not sure this is really a bug, but on my MacBook Pro 2019 (2,6 GHz Intel Core i7 6 core, Radeon Pro 560X 4 GB
Intel UHD Graphics 630 1536 MB) GPU memory usage skyrockets each time I launch Warp, whether it is idle or running any command (see attached screenshot, source: iStat Menu).

To Reproduce

Just launch the app

Does this block you from using Warp daily?

Yes

Warp Internal (ignore): linear-label:b8107fdf-ba31-488d-b103-d271c89cac3e

None

Hey @Elzonor, thanks for letting us know! A couple of questions to help us investigate more effectively:

1. How many Warp windows do you have open?
2. What font and font size are you using?
3. Do your commands produce output with a lot of emoji or CJK/non-Latin characters?

How many Warp windows do you have open?
Just one.

What font and font size are you using?
My configuration in the attached screenshot (I think it's the default configuration)

Do your commands produce output with a lot of emoji or CJK/non-Latin characters?
No... just connecting via SSH and launching server-side jobs (no fancy characters)

I double on this. Warp is even shown in the list of Apps, that are "Using significant energy" (Intel Mac with Radeon GPU)

[GreyTeardrop]

Same for me. Even if left in the background doing nothing Warp causes my MacBook Pro 2019 to switch to a discreet GPU (everything else is ok with the integrated GPU), which causes the laptop to turn on its fan even if it's doing nothing. That unfortunately is a blocker for me for switching to Warp as my primary terminal.

[vorporeal]

Hey all! I've sent out some changes internally which should reduce GPU memory usage a bit (though I don't know what could possibly cause Warp to use 100% of video memory when the GPU has 1.5GB of memory available). Additionally, these change should make it easier for us to support you choosing whether to use the integrated or discrete GPU; not sure when I'll get a chance to implement that but it's definitely on my list of things to tackle in the not-too-distant future.

@Elzonor Looks like this might be a known issue in iStat Menus with reporting of video memory for AMD graphics chipsets: https://bjango.com/help/istatmenus5/knownissues/#gpu-shows-100-memory-usage

The same issue is on fresh MacBook Pro with M2. Warp uses significant energy and dries the battery even in the background (no activity) which is more than weird. This makes it unusable for me.

[thatsk]

i just installed linux version it dries the battery . SO this is weird in first place. Until this battery issues get resolved

No wonder my MacBook is dying so fast.

Less AI features, more power optimizations

I've tried Warp terminal on Windows 11 24H2 laptop with fresh Intel GPU drivers (v32.0.*). Laptop has 16gb ram, Intel Iris XE graphics, 3000x2000@90hz screen. It uses quite high amount of memory right from the start, about 550mb for VRAM and about 350mb for private working set (with AI stuff off). Since GPU uses ram as a source of memory dynamically, it means that Warp terminal app uses almost 1gb of total memory out of 16gb right from the start!

[ai-toast]

I am running Warp on Win11 24H2 with similar specs as @ChGen.
Out-of-box, the memory and cpu load killed my machine.

I turned off AI and that brought the memory footprint to 250-300 mb and way lower cpu load (no more spinning fans).

There's also a switch under Settings.Features to use igpu for rendering with the promise of low power. My machine just has the igpu so can't tell the difference. vulkan vs directx12 backend doesn't make any difference for me.

cpu spike after each command still happens; i guess it's indexing every output.

Man this is why my brand new MBP has a worse battery life than my ancient one: I decided to switch to Warp lol.
Turning off AI in the settings completely negates the drain (according to Activity Monitor).

Warp has been draining my MBPro m4 using an insane amount of energy. Typically when warp is open, vs code and chrome is open at the same time and the difference between applications energy usage is extremely large, especially considering my execution environment is a remote server. I have disabled AI features, hopefully this resolves my issue.
