from what I have found, when getting "Can't find 'rt/bin/RTGL1.dll' file", thats the rtgl dll not being able to get vulkan-1.dll

I only get this error when setting winecgf > Libaries > [add vulkan-1] > then set it to "native (windows)"

now when using anything but "native (windows)", rtgl does get loaded in theory, but vulkan has an issue with my gpu not having extensions

the issue here is that those are windows specific extensions to vulkan on windows all wine here is doing is passing vulkan commands to linux, but linux dosn't have the win32 extentions

ps: people have been able to get these extensions to work running things under proton 7 https://www.pathofexile.com/forum/view-thread/3376621

[ravachol]

Thanks, I tried what you suggested including proton 7 but it still complains about no vulkan extensions.

Hi, how did you manage to make it find your Steam installation of Doom? I tried installing steam for windows in the same wine prefix but it complains about having no internet connection...

[ravachol]

I copied the wads from steam to the gzdoom-rt directory.

[KingVulpes]

Hi, would you happen to know where the config file is stored on Linux? On windows it's in Documents/My Games/GZDoom. But on Linux I can't find it

[ravachol]

Don't know.

[KingVulpes]

Don't know.

Dang, I was asking because you can switch it to use DXGI instead of Vulkan

[ravachol]

aha

[ravachol]

/home//.config/gzdoom/gzdoom.ini. But I don't know what to change.

[KingVulpes]

/home//.config/gzdoom/gzdoom.ini. But I don't know what to change.

Change the rt_dxgi to true

[ravachol]

hmm, can't find it, that might be a config for normal gzdoom..

[KingVulpes]

hmm, can't find it, that might be a config for normal gzdoom..

You're right, the Doom 2 RT one is called gzdoom-rt2.ini

[KingVulpes]

hmm, can't find it, that might be a config for normal gzdoom..

Tho maybe it's the same location? If you want I can send the Doom 2 RT one and see if putting it in the directory would work

[ravachol]

Sure.

[ravachol]

the My Documents/My Games/GZDoom/ folder is empty.

[KingVulpes]

Sure.

[ravachol]

Thank you, I will try this later.

[ravachol]

It still complains about no_vulkan_extension, unfortunately, but thanks for the help.

Darn :(

[KingVulpes]

Potential solution, put: gzdoom.exe +rt_dxgi 1 into a .bat and launch it. I can't test it since SteamOS won't even load the .exe but your distro seems to be able to load it

[ravachol]

doesn't seem to make a difference.

[SoftwareSchlosser]

I copied the wads from steam to the gzdoom-rt directory.

I still get the error message that DOOM2.WAD couldn't be found. I copied all the wads from the "Ultimate Doom" steam game folder to the folder containing gzdoom.exe. Am I missing something else?

[ravachol]

I used the wads from doom1 + doom 2

[SoftwareSchlosser]

Yes, "Ultimate Doom" is just the name of the game folder in steam, it contins all WADs including those from doom 1 and doom 2 which I copied over to the gzdoom folder. Can't see why it doesn't work...

[ravachol]

No Idea why it doesn't work, that's what I did.

All you need is Doom2.wad which is in base/doom2. Copy that ONE file right next to the EXE

[ravachol]

Maybe it's a character case issue.

[DwayneHawkins]

Maybe it's a character case issue.

I don't think so, the casing seems OK.

Seems related to (https://github.com/vs-shirokii/gzdoom-rt/issues/1) / (https://github.com/vs-shirokii/gzdoom-rt/issues/21). For some reason, when installing the game in linux, it seems to download a different wad file! After installing the game in windows and copying over the wad file from the windows partition (which is obviously the same as in AKbar30Bill's repository) the selection screen appears but after choosing Doom 2 it get's to the cannot find 'rt/bin/RTGL1.dll error. Tried copying the files over from proton (Proton GE in my case -> ../files/lib64/vkd3d/libvkd3d*) to the gzdoom-rt folder which leads to another error message box with title "Unsupported GPU" and text: "VkDevice extensiond are NOT supported: VK_KHR_external_fence_win32".
