<![CDATA[everything is rendered on the cpu]]>it seems like everything uses software for rendering, and the gpu is always idling
every application runs slowly and lags, drops a lot of frames, while cpu load is abnormally high
the web browser and any web apps are practically unusable due to this, any web page i open runs at like 5 fps
i've searched for this issue online but haven't found anything on it
after watching some youtube videos of how ut runs on the nexus 5 i think i am the only one to encounter this
is it a known issue at all, or have i run into some very specific configuration? it is like this on a fresh unmodified install too

Can't remember if it was better before when I actually used it. I updated to the latest (04/2023) and I do noticed that the system is overall more sluggish. Not really sure what's happening here. I really wish the installer is capable of installing specific version. On the unsupported MutiROM on my Nexus 5, it's possible to specify which version to install so I think it should be technically possible.

i am hoping the problem could be resolved soon, because i need to use alarms and reminders while also being able to occasionally look up information on the go
maybe you could tell me where can i see some logs related to it so i can try figuring out the reasons behind low performance?

i don't think this is a hardware issue since ut vivid and android run fine

If anything, it should be smoother now. Have you tried fully reflashing (wiping data) if that's something you're okay to do?
I realized this is quite similar to my MX4. It suddenly felt so sluggish and charges so long. I already wiped it clean but still the same. Not really sure what happened to it. Maybe it's already a hardware issue.

tried it from different computers running silverblue and opensuse, still run into the same result
i know the hammerhead is supposed to run ut well, i have been using it on vivid without problem, but when i installed xenial i noticed everything no more runs so well, even the ui is somewhat laggy, the frame drop is pretty noticeable where it wasn't present before

System UI is hardware accelerated but media playback on any webview isn't. They should still be good enough though. How did you even downgraded to vivid? How are you installing UT?

i like xenial more, where do i look to find the solution?
