Asus ROG Ally performance

I split my windows partition and installed bazziteOS so I could dual boot. I did so to test performance back and forth. I assumed with a more streamlined OS that my performance would increase compared to Windows, but I had substantially worse performance in The Witcher 3 on Bazzite. I set the tdp to 18w on both (I used decky loader TDP plugin to set it on Bazzite) and same graphical settings. Bazzite got around 35 and Windows ~50 fps.

I have seen other have at least the same, if not better, performance with Bazzite, so I’m sure I’m missing something. Any ideas?

did you disable cpu boost on the windows side?

Aru•3/20/24, 11:49 PM

it could be that the Ally's cpu boost problem is similarly affecting your performance numbers on Bazzite

AAru did you disable cpu boost on the windows side?

I do have boost disabled on windows. What do you think would cause boost ON to drop the fps so much? I’ll test it, just curious if you knew why it may cause it.

I think it's just something maybe hardcoded by Asus on the Ally somehow

@Smabe disables CPU boost on the Ally, which helps a lot

Smabe•3/21/24, 1:54 AM

yeah the cpu will eat up most of the headroom the gpu has on the unit

I should add an option to simpleDeckyTDP just for ally users only

different from just a toggle to enable or disable?

Smabe•3/21/24, 1:55 AM

oh right you have to set your amd_pstate=passive

Aru•3/21/24, 1:55 AM

so amd-pstate-epp, the scaling driver enabled on most steamOS-like distros, actually won't support cpu boost at all until some upstream changes in a future kernel

Aru•3/21/24, 1:56 AM

so CPU boost control doesn't actually exist unless you manually change your scaling driver

Smabe•3/21/24, 1:56 AM

could have something like antheas suggested like capping max freq for the cpu

Smabe•3/21/24, 1:57 AM

it overs around 3.3ghz with cpu boost disabled

Aru•3/21/24, 4:21 PM

for future reference, if anyone needs cpu boost, they can change the scaling driver to passive

then reboot

Quick question: is cpu boost disabled by default in bazzite?

Nope, you need to change your AMD scaling driver if you want access to CPU boost controls. It's documented on the SimpleDeckyTDP GitHub, if you want to enable it.
