I have no problem with it squeezing out the last few percent using the GPU.

But look at my CPU charts in the github link upthread. I understand that maybe that's due to the CPU emulating a GPU? But from a thousand feet, that's not viable for a text editor.

Yeah LLVMpipe means it's emulating the GPU path on the CPU, which is really not what you want. What GPU do you have out of interest? You have to go back pretty far to find something which doesn't support Vulkan at all, it's possible that you do have Vulkan but not the feature set Zed currently expects.

It was ASUS GeForce GT710-SL-2GD5 . I see some sources putting at at 2014. That's not _recent_ recent, but it's within the service life I'd expect.

(Finger in the air, I'd expect an editor to work on 20 year old hardware.)

Sold it ages ago. New one (Intel) works fine.

I was running Ubuntu. I forget which version.

That's pretty old, the actual architecture debuted in 2012 and Nvidia stopped supporting the official drivers in 2021. Technically it did barely support Vulkan, but with that much legacy baggage it's not really surprising that greenfield Vulkan software doesn't work on it. In any case you should be set for a long time with that new Intel card.

I get where you're coming from that it's just a text editor, but on the other hand what they're doing is optimal for most of their users, and it would be a lot of extra work to also support the long tail of hardware which is almost old enough to vote.

I initially misremembered the age of the card, but it was about that old when I bought it.

My hope was that they would find a higher-level place to modularize the render than llvmpipe, although I agree that was unreasonable technical choice.

Once-in-a-generation technology cliff-edges have to happen. Hopefully not too often. It's just not pleasant being caught on the wrong side of the cliff!

Thanks for the insights.
