judging by the log, looks like a missing wined3d format:

154303.907:0024:0032:err:d3d:resource_unload Resource 0x16dcf3f0 is being unloaded while mapped.
154303.915:0024:0025:fixme:d3d:debug_d3dformat Unrecognized 0x34324644 (as fourcc: DF24) WINED3DFORMAT!
154303.915:0024:0025:fixme:d3d:wined3d_get_format Can't find format unrecognized (0x34324644) in the format lookup table.

and me no have black screen have cinematic and crash in proton 3.7-8 and 3.16-3

As a point of data, the game seems to work perfectly well here except it has no audio (literally there is not even an audio source popping up in Pulseaudio itself). But the game runs well, efficiently, no missing anything as far as I can see, etc...

Work on Proton 3.16-4 Beta ! https://gist.github.com/liberodark/b09b4b17857325780f8c4b37391ed4e8

Just have no sound xbox controller work

The game is known to insta-crash with any CPU that has SMT even under windows.

In Windows it can be workarounded by running the game with affinity 0xff (or less). No need to change something in bios. It just don't support more than 8 cores.

It seems to be a recurrent issue, though. Other games also have problems figuring out which resolution to use when none has been set manually (i.e. after installing the game)

Did you tried fixed dll from PCGamingWiki? https://www.pcgamingwiki.com/wiki/Prototype#Widescreen_resolution
Still, it shouldn't crash anyway.

Game starts into main menu but crashes on starting a new game (select save slot -> saving -> game begins to load -> crash).

Controller does not work in main menu, but does it working in native Windows either? Store page does not list controller support.

steam-10150.log

The game load, but without audio.
steam-10150.log

Found no Audio issues, but the game freezes when loading a new game/save

Hardware
Steam Deck latest Stable
Proton 7.0.6

Symptoms
Hangs right after starting gameplay

Reproducibility
Open the game, set your settings (I maxed them given the games age) and play for a few seconds before it freezes.

is this thread still readable though ancient? the problem seems to go a ways back

Compatibility Report

• Name of the game with compatibility issues: Prototype
• Steam AppID of the game: 10150

System Information

• Steam Deck 512GB
• OS: SteamOS Latest Stable
• Proton version: 7.0.6

People report on protondb that Proton 6.3-8 runs it perfectly, other say it works but with no audio. In any case, it seems to be a regression.
The game currently has a Steam Deck Playable rating which it probably shouldn't have as of now. The game for me, seems to only run correctly on one old build of Proton GE, Proton-7.1-GE-1. Anything else, including new official proton versions or new GE builds will have the freezes.

Symptoms

Game freezes moments after getting to gameplay

Reproduction

Pick your settings (I maxed them given the game's age)
Launch the game, start a new file, skip the cutscene, play for less than a minute before it freezes

How do i upload the log from the steam deck?

steam-10150.log
log of crash on 7.0.6

Do you need me to test that in 7.0.6? Do i do both or one at a time?

It might be interesting to test if setting the game's launch options to PROTON_NO_FSYNC=1 %command% or PROTON_NO_FSYNC=1 PROTON_NO_ESYNC=1 %command% has an effect.

do you still need a test of these two parameters? i've been using the ge version but i can try

any news on this?

For me it crashes after a bit of the first mission on the steam deck without disabling fsync, tried beta candidate / main with proton stable.

The game is also quite choppy if i have vsync on and 60 limit but that might be gamescope.

Prototype 2 also says playable but i never was able to play it, it crashes right at the start.

Has this been fixed??? @kisak-valve

According to pcgamingwiki and testing on my deck, the game will limit you to only using 2x MSAA on any device with a gpu that has more than 2gb of vram. It works if I use the specific PrototypeFix patch to limit the VRAM, but I can't seem to do it with DXVK.

Seems to occur on Prototype 1 and 2.

Hello @waspennator, it might be interesting to tinker with a dxvk config file beside the game's executable and d3d9.maxAvailableMemory in a similar way to doitsujin/dxvk@51e56c0.

I tried doing it on my deck and on my windows laptop, but I wasn't able to get it working whether through the command line on deck or through the config file on windows, dunno if i was doing something wrong or not.
