Haunted Hardware Ep. 1 - Doom Vulkan Error

[nicklmg]

Buy Doom for PC on Amazon: http://geni.us/BeA69

 

Have you ever had a hardware bug SO WEIRD that it feels as though your PC is... haunted???

Do I have to wear my "Red is Scary" shirt?

[Imakuni]

Haunted PC? Yes.

 

I have this super weird screen glitch that sometimes happens when I go to sleep and wake the PC up in the morning

One time I got a virus on my laptop that had.... interesting effects. Long story short, I'm going to sleep and suddenly my laptop starts speaking rapid fire Spanish. Absolutely terrifying.

That's either GPU or monitor problems, if you try a different monitor and it still happens then your GPU is a little screwed up and needs to be replaced.

Rocking a 1st gen APU. Hard to replace the GPU on that thing...

[zMeul]

oh god .. Linus destroys more HW

 

back on topic

it shows the counter because the iGPU is active or it shows because of some other OSD is active

[Gravemind]

I'm still haunted by the infamous "Windows 7 white pixel in the corner of the Desktop" bug that nobody has a fix for.

I think that Doom implements Vulkan by wrapping it in a DX presentation layer. Doom already works smoothly with DX, and instead of rewriting alot of calling code, the programmers probably found it easier to stick with the DX calling convention and wrote a passthrough wrapped over Vulkan.

 

What happens is that Vulkan renders the game, then the rendered frames gets passed/copied to a DirectX instance which handles the swapchain and presentation. Fraps hooks to the backbuffer which is handled by DX, not Vulkan. But the game is rendered with Vulkan.

On one of my old PC's(socket 7 rig - 150Mhz cpu, 16Mb ram, 1Mb gpu, windows 98) I had this a really weird "issue". Since the PC was not powerful enough to run windows 98 properly it was very slow, even playing music on it would result in the music stuttering. That's until you put a CD in the CD-ROM. It doesn't matter what CD, the moment you put a random CD(even if the PC doesn't read it, yes, had this issue too, it would only read disks if you put them right after the OS booted) in it the computer would just run faster, music will play fine, hell, I even managed to play StarCraft and Heroes III on that thing. I still can't explain it. It doesn't make any fucking sense.

Without rewatching the video, I think Linus showed it running on a desktop without the counter present. This only happened on that laptop. I managed to replicated it on my laptop, and fraps will even capture video in Vulkan mode. What I think is happening is this is a side effect of nvidia optimus technology. Although Linus tried to disable the integrated graphics, I think it has to remain active as it is connected to the display. The nvidia GPU still has to pass display data through it, and fraps may be intercepting at that point. If this is correct, this effect should be repeatable on optimus enabled laptops, but not other laptops or desktops.

I would expect the same behavior on the desktop then.

 

In my opinion:

The way FRAPs runs is by setting hooks into the OpenGL/DirectX code where FRAPs is notified every time a frame is drawn. If I had to make a guess as to what was going on here the 1060M drivers are probably using the Vulkan API to do most of the work before passing the completed frame to OpenGL/(or more likely)DirectX APIs for the actual display for compatibility/hardware reasons. Since it is doing this FRAPs is still able to count the number of frames pushed per second and display the FPS counter. A good way to test this idea would be to actually hook into the APIs yourself and see if the frame is being pushed with OpenGL/DirectX (easier said then done).

 

If this idea is true it is most likely happening at NVIDIA's driver level and would be present on all 1060M laptops. If I had to take a guess as to what is causing this is NVIDIA's Optimus technology pushing all frames through the integrated graphics chip. (Check out the Optimus Whitepaper if you're feeling nerdy.)

 

TLDR; Turn off Optimus and try again.

Couple of years ago my friend from school had a PC. It wasn't anything fancy... well, it was completely opposite. It was old and really, really slow. Nothing weird. Or is it? As the PC was really old, sometimes when my friend was playing some games or simply surfing the internet his PC would freeze or some other glitches would be encountered. There were only two, (three, if you count buying new PC), ways to fix it. Either restart the computer or, and that's what my friend preferred to do, slowly and with complete poker-face pull the hammer out of the drawer and placed it nicely on the desk. It worked like a charm. I didn't believe it until I saw it myself. It looked like the PC would get scared of the hammer and would stop glitching. It didn't work with my PC tho... SPOOKYYYY

Reminds me of a problem I had on 2 computers at once that I never found anything on. Windows Explorer on my laptop and main desktop at the time would crash repeatedly while trying to navigate files but only if I ran anything that pushed the GPU out of desktop mode. I mean anything. If I watched a YouTube video or if I ran any game, etc. If I restarted the computer, it would be fine until I ran a game or whatever.

 

The only thing the two shared in common was that they both had dual core AMD CPUs with 4GB of RAM and Windows Vista Home Premium x64. Other than that, they were pretty different. Desktop had an Athlon X2 6000+ on an ASUS board with an nVidia nForce 590SLI chipset and I think a GeForce GTX 275 (I may have still had the 8800GT). The laptop was an HP with a Turion X2 RM-74 using an AMD chipset with integrated ATI graphics of some kind (I think Radeon HD3000).

 

The problem showed up at the same time and disappeared at the same time on both. I still have no clue what the problem was. I couldn't find anyone else with the same problem.

My university laptop was behaving really weirdly at times. Many times when I was taking notes in Word, the screen would just randomly became really, really white for about a minute and then go back to normal. And now it doesn't happen any more. Now it just randomly freezes without any explanation, I've tried to diagnose it with everything I can think of, and the only thing left that I can think of is that the boot SSD connector is loose or something.

As some other people in this thread have said, I also think it has to do with Optimus or possibly some G-Sync thing.

Linus, could you try plugging in an external monitor and see if it still does the same thing?

Optimus transfers the display surface from the dGPU frame buffer over the PCI Express bus to the main memory-based framebuffer used by the iGPU. It might be that on the recieving end nVidia Optimus is using DX to present. Another possibility i can think of in this case is that WDDM 2.0 is so intertwined with DX such that Cross Process Resource Sharing makes Vulkan to present to WDDM, and then shared to another WDDM process where Fraps picks it up.

Maybe MSI is fucking with your head Linus. Did you upset them recently?

[Sauron]

There is a separate executable for vulkan, maybe you should investigate around that.

[FrontsLeader]

BTW fraps with probably Dx12 and Vulkan  support is in development

as well as a real Windows 10 support

Maybe it's the mobile implementation of Gsync? That persists through a drive format.

That's what I was thinking. Makes pretty good sense. :-) It doesn't switch drivers according to wikipedia: https://en.wikipedia.org/wiki/Nvidia_Optimus

Whenever I insert a USB storage device my background changes to black or just some random characters. Unplug it and my background comes back. IDEK

I have an FPS counter on all of my games, yet I do not have Fraps on my computer anymore.  I have reinstalled it, deactivated the counter, then uninstalled it again, yet I still have this counter.  Is this coming from another program?  I have MSI Afterburner and SpeedFan installed, but I don't think I ever activated a counter on those, and I've gone into Steam's options and the box isn't checked there either.  It's not a big deal, but I don't really want it there anymore.

 

Any help is greatly appreciated.
