DDraceNetwork

I couldn't start ddnet on my windows

15:34

the last message it showed was setting up some vulkan stuff

15:34

it's probably a known issue

15:34

but it would be nice if it could be resolved without the user looking something up

15:35

computer has a intel onboard graphics card and a nvidia graphics card

Did setting opengl by hand get it to work?

I didn't know what to do at the time and I just gave up on it instead

15:35

was trying to show the game to someone

15:36

I can try that now I guess

its probably a bad driver install

ddnet is the only game having a problem with it. does factorio use directx?

15:39

perhaps we can try to detect that driver problem and fall back to older opengl when vulkan crashes at start?

DDNet doesn't use DirectX does it

apparently it does

perhaps we can try to detect that driver problem and fall back to older opengl when vulkan crashes at start?

it already does that

15:39

its probably a very broken setup u have there, where it says it has vulkan

it's apparently a real-world setup

15:40

I didn't change anything wrt. that

anyway u can try detecting your issue, maybe u'll find something out

ah yea, factorio uses directx, you're right

i can just tell ya we have a fallback system which was also tested

does it fall back to opengl if vulkan initialization crashes ddnet?

well vulkan initialization should not crash in first place

should not, but maybe it does there?

is your windows up to date?

I'll check whether I have crash logs

15:42

maybe it lags a couple of months behind

maybe try that first before wasting your time

ok

updated, didn't change what happens

16:17

it works with gfx_gl_major 1; gfx_backend opengl

16:18

with vulkan it fails like this:

so where does it crash

it's not creating a crash dump, so I assume it doesn't crash?

i dunno

I looked into the dumps folder, didn't see anything there

if it doesnt crash what else does it do, maybe attach a debugger

16:20

the drmingw cant catch everything

I guess I have to install msvs to get a debugger?

does gdb not work without msvs?

I actually don't know. it's a relatively plain install of windows, I haven't installed any debuggers

16:21

maybe I can install x64dbg

16:21

that was kind of lean
