This is expected, game in Vulkan runs only in borderless or windowed mode, there is no exclusive full-screen mode.

Your beamng log is just working game, there are no issues since it's DX11 log

Greetings. Developers, can you tell me why the game only works in windowed mode and in borderless mode via Vulkan API? What is the reason for this? Why is the exclusive full screen not available?

When I go to controls and then add new control binding, for some reason new binding is not showing up, in fact all the bindings become multiplied instead, then I click audio from the left and click back to controls and now I see bindings normally again.

I think this was one of the reasons why I resort to DX11 mode, UI seem to generally have more glitches in Vulkan mode.

After updating my gpu, when trying to launch vulkan the game only runs in the background and doesn't start, I've tried running in safe mode which yields the same results. I've been currently using my laptop since as of right now I cannot use my pc, my laptops specs are:
Processor AMD Ryzen 5 3550H with Radeon Vega Mobile Gfx 2.10 GHz
Installed RAM 8.00 GB (7.43 GB usable)
Storage 477 GB SSD Micron_2200V_MTFDHBA512TCK, 932 GB HDD TOSHIBA MQ01ABD100
Graphics Card NVIDIA GeForce GTX 1650 (4 GB), AMD Radeon(TM) Vega 8 Graphics (498 MB)
System Type 64-bit operating system, x64-based processor. Can confirm that the game launched in vulkan before I had updated my graphics, and here is the log file, the log file was created in safe mode by the way.

Okay the issue was I had to add the DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1 enviroment variable and now the game launches

Please report issues only from BeamNG 0.38 from now on
There are some fixes for Vulkan in this update, but nothing major.

Neverless · Dec 15, 2025

This issue from 0.35 is still present in 0.38 and not listed on the known bugs list.

Ive switched to linux since then, so i cant tell how its looking over at windows atm, but i have the epileptic invoking errors when i run the game natively or over the proton layer and they are visually the same as the one i had shown in the video.

My specs are:
OS: CachyOS (Linux 6.18.1-1-cachyos-bore-lto) w. KDE over Wayland
everything else the same

Altough i did see people talk about this issue since 0.38, so i guess its still a thing on windows either.

Relating back to what i wanted to report here but then didnt because it seemed that it was gone. However just the conditions have changed and given that i saw alot of reports of it in various discords i thought it was already reported here, but hasnt been or so it seems.

Bug
Heavy graphical glitches that get worse the more vehicles are spawned and the lower the fps go.
See video.

Please not just note the obvious graphical glitches! Also see how the ui sometimes vanishes, how the lod in the background changes and how the debug spheres spazz out.
There is more to it, sometimes vehicles also go invinsible for a moment and objects appear at higher positions then they actually are. Imagine the blue balls suddenly appearing a meter higher in the air for a moment.

How to reproduce
1. Spawn into any map
2. Spawn a bunch of vehicles
3. See graphical spazz

Before you ask, yes this also happens on every other map and in safemode. The more vehicles spawned and the worse the fps -> the worse these glitches get on my end.

My specs are:
OS: Windows 10 Pro 22H2 (19045.5487)
CPU: i5 9600K (6 core)
GPU: AMD Radeon RX 7700 XT (Driver v.25.3.1)
RAM: DDR4 32Gb @ 2666Mhz
Dxdiag: Shows 0 errors

This gets so bad at times that i fear of getting a epileptic attack

hmmm, i have had this weird issue with vulkan, but its slightly different than you.
i quoted my message from another thread for more information.

is it just me or vulkan on native linux build is utterly unstable and literally will crash your whole pc?...

its so inconsistent, wednesday i played for 8 hours straight no crash.
today? 30 min and it utterly borked my whole pc. i couldnt even launch terminal ffs.
it borked my pc so hard it didnt even create a log this time around.

BUT!
i will try to put as much information, but im uncertain if this is two unrelated issues.
im running linux mint 22.2 with a ryzen 5950x and an RX7900XTX with 32gb of ram.
every graphics settings is on ultra/highest i can possibly put it. 1080p tho
now since the update, ive had weird visual artifacts rarely when spawning a vehicle.
View attachment 1272709 View attachment 1272710
the odd thing is, if i reload the vehicles itll reload properly with fixed textures, but shortly after i took those pictures, the game crashed and it hung my whole system, i rarely can get control of my pc back without restarting at this point.
BUT!! the log i attached shows a lot of these
Code:
928.56681|E|vulkan| Failed to wait on Finished Frame semaphore
928.57061|E|vulkan| (submit) Failed to submit to transfer queue [ErrorDeviceLost]
928.57061|E|vulkan| Failed to submit to graphics queue [ErrorDeviceLost]
928.57074|E|getStatus| Failed to get occlusion query status: ErrorDeviceLost
ive never seen ErrorDeviceLost in my life happen before.
vulkan seems to straight up crash and lose my gpu entirely.

im not sure if the two crashes ive gotten here are related, but regardless, for me, the native linux build with vulkan is a buggy pos that borks my desktop at any given moment.
and the most annoying part is how inconsistent it is, i enjoyed no joke, 8 hours straight of 0.38 when it released wednesday, and today i cant even play 30 min without the game shitting itself and borking my whole system.

This is a critical bug in my opinion.

but it also happens in windowed mode, sometimes a vehicle will spawned with glitched textures and i got used to closing the game instantly when seeing gfx glitches because not too long after i notice that i always get a hard system crash.

i hope the devs will eventually fix this, as the native linux build is a pretty solid contender if it wasnt for this major glitch.
