Vulkan API – Feedback, Known Issues, and FAQ

So basically anyone that does not have newer high-performance cards are screwed graphically for now... Yeah, my 4 GB system is being rapidly outpaced by the gaming landscape.

Any news on AMD optimization?

 

Better than nothing at least, looking forward to the patch notes
And yeah, I might be best off lowering the texture settings since my card only has 8GB VRAM.

I'm not sure about AMD on D3D11, @zachariah.74 might know a bit more. But regarding Vulkan, it's still in its early stages. But for me and many others, there's a huge performance gain. It's usually a 40FPS gain for me, tested it on quite a few maps. This might increase or decrease in the future, who knows. But they will definitely be trying to make it work well for all users, including AMD. Also, one of the developers there (I believe Lefteris, aka estama) tests BeamNG on low end hardware. I'm not sure if he's the only one, but I think it's nice that he does it.

And on D3D11, my RTX 2080S also struggles, especially when upping the reflection's update time or changing LOD with Car Killer's mod. But then again, the engine developers (which I don't think there's many of) are working hard in the graphical department, trying to optimise things and make things look better. So things will probably be a lot better in the future

 

You can also test DXVK to see a third result, perhaps it's better than native D3D11?

 

Out of interest, is the Vulkan renderer using AMD's open source Vulkan Memory Allocator?

 

Probably, VMA is honestly really neat and a lot of developers use it. I suppose I am a tiny bit curious though

 

So, when i try to launch the game in Vulkan mode, nothing appears, but the game runs in the background; and i already tried reinstalling the game, updating my drivers, but it still happens. Specs are: (Laptop) Geforce GTX 1650, AMD Ryzen 7 4800H, Windows 11, 16GB ram. Also the game runs fine in DirectX mode. It doesn't give an error, only when i close the task: "BeamNG.drive 0.31.3.0 0x00000001". Nvidia driver version: Geforce Game Ready 552.12

UPDATE: turns out vulkan was actually running in the integrated processor's graphics card, so i disabled it and it works! it was my problem. i will find a way to keep the nvidia card running with the vulkan runtime.

 

Didn't see the mention so that will explain my late addition to the topic, but for me performance on my AMD GPU with 16GB of vram it seems to just vary wildly between maps in D3D11. Sometimes it works fine, other times im dipping to around 80fps with a single car (first world problems, I know, but sometimes it'll be at my 144fps cap with a single car.)
"AMD optimisation when?" is a bit of a tin of worms because I don't even know where the problems lie or if the problems exist at all. I can't remember having as frequent inconsistent performance on my old Nvidia. Vulkan, predictably, is iffy for AMD right now and I think the performance gain for me is almost negligible but I need to do some more extensive benchmarking when the next update comes. Barely any point doing it now with the new update very nearly here.

 

It seems the game is choosing the wrong GPU and it's not the IGPU fault, any way i could just change the GPU being used by Vulkan?

 

With the new update, I've recently been seeing weird flashes on-screen when using traffic (or maybe without). I use Vulkan when I play career mode, and that's when I noticed it. Sometimes it flashes different colors, other times it makes the game look like it has photo mode filter effects applied. It only happens with Vulkan, and the easiest (and maybe only) way to replicate it is to do this:
- Start BeamNG with Vulkan, with no userfolder (vulkan safe mode without debug I guess)
- Alt-Enter to go into full screen before clicking on any buttons in the main menu
- I used different settings than default, but I only changed graphics and traffic settings (change them before loading into a map)... Here they are:

- Go into a map, and spawn traffic, and drive around
- I find it happens more often if you go down a long stretch of road...

I reinstalled Nvidias newest drivers and used the default driver settings, and it still happens... Also, here's a video

 

Can't launch the game in Vulkan mode. Error:BeamNG.drive 0.32.1.0 0x00000001

Already tried：Updating the drivers,Cleaning cache,Trying Safe Mode

 

Is lighting flickering in vulkan mode a known problem?
Is that the case for everyone, or am I the only one who is so lucky?

 

I see flickering on the left half of the frame. I just tested and can confirm flickering in Vulkan, but it's super rare on my end, nothing like on the video. Happened like twice in 2 minutes of staring at the game.

 

The flicker is clearly visible - it hits my eyes, is that why I temporarily stopped using vulkan.. record more videos?

Yes, that's it, sometimes an object flickers, sometimes a headlight, each card has its own jokes, I started to think that my video card was dying

 

My video card doesn't play nice with Vulcan (as of 0.31). So your better of than I am.

I remember when 4GB of VRAM was good

 

yes i did look at it and i also have flicker every 20-10 seconds

 

im dumb what does vulkan API do

 

So what's going on with the flickering of the left flashlight or some textures of nearby objects? Can you confirm the problem? I asked the guys to check yesterday and everyone confirmed the problem except the officials)
