Does not work at all on steam deck.

[ranagard]

Desync audio for the intro and then when game loaded in the first stage got a frozen screen.

It`s working well on my deck

nice. ill reinstall and try again. thanks for update.

Came here just find out about this. It says it's unsupported but that doesn't mean it's not playable with some controller configuration tinkering. Guess I will install it and find out.

Anyone else share their Steam Deck experience with this game?

quick update yea i was able to get the game up and running. I think the issue that caused problems was that i had tinkered around with the frame rate settings and stuff. The game does work perfect. If you're having issues i can post my settings but the game does work at this time.

as a side note, while the game ran just fine in my experience, it drains your battery like a monster compared to other games, since it seems GPU usage stays constantly at 100%. might improve in future proton releases, but I'd recommend checking the battery overlay to make sure you know how long you'll be able to play

TLDR:
DO NOT USE 'Highest' SETTING FOR ANTI-ALIASING!!!
USE 'High' IF YOU DON'T CARE ABOUT BATTERY, 'None' OR 'Normal' IF YOU DO

hey, turns out the performance issues on the deck were mainly related to the anti-aliasing settings!

my guess is that the 'Highest' setting is using a DX12 exclusive AA technique, and DXVK probably struggles to reproduce it. leaving it on makes the GPU consume around 10W-13W. for comparison, most games can run on the deck using 7W total, with GPU usage being around 2W-5W.

if someone reading this plans to play the game on the deck, or if your Linux PC is struggling to run it, here's what I recommend you to do:

1. in the launcher, go to the 'Graphics' tab and change the bottom left 'One-click Setup' option to 'High-Spec'.
2. change anti-aliasing from 'Highest' to either 'None', 'Normal' or 'High' (read bellow).
3. (for Deck users) 'High-Spec' defaults to 1080p, but since the deck doesn't support that, the game fails to load. change it to '1280x800'

now, the AA option choice will be mainly based on preference:
- 'None' disables AA, and leaves GPU consumption around 1.8W-2.3W, which is good. that said, you get what you expect: choppy borders.
- 'Normal' applies some simple AA, which ends up with washed colors, mainly on borders. that said, it does get rid of the choppy borders, and the consumption is pretty much the same as 'None', around 1.9W-2.5W.
- 'High' looks great, but ends up bumping GPU consumption quite a bit. from my tests, that was around 4-5W.

I'm fine with choppy-borders, so I'm playing with 'None', but again, that's up to preference.

Considering the game release date I doubt the AA is using a DX12 or even DX11 exclusive setting. More likely the choice ends up between FXAA and MSAA x2 x4 or something to that effect. In general AA is very expensive and I would just disable it or use the lowest setting on most games when on battery, regardless of the machine you use.

[Rockisch]

the original game on the PSP didn't have any AA implemented. and the game does run under DX11 on PC. I just said DX12 because DXVK is a DX12-Vulkan layer, so technically it is trying to translate the DX12 implementation of whatever was done in DX11.

and idk what they choose, but I've been able to run other games on the deck with FXAA and MSAA turned on without reaching those levels of GPU usage. my guess is that those are being used on the 'High' setting (which does double the GPU consumption), but 'Highest' either uses something DX specific, or had a terrible implementation. perhaps the latter is more probable, given the game is a port after all.

Is there any way to push Valve to run the certification again on this game? It should really be changed to "playable" at this stage (because of touch screen launcher). But definitely not unsupported, I would like to see games like this promoted for steam deck so more publishers can see there's a market for PSP games to be ported to PC now with steam deck (like the PSP Valkyria Chronicles games...)
