nvidia-bug-report.log.gz (293.4 KB) When playing CSGO using Vulkan, after about 20 minutes of gameplay, the performance goes to the level of slideshow quality. Running nVIDIA RTX 3080Ti with NVIDIA-Linux-x86_64-515.48.07. Linux cyberdeath-pc 5.18.0-1-rt11-MANJARO #1 SMP PREEMPT_RT Sat May 28 15:4…

Looks like there’s an interrupt storm happening, did this also happen with the 510 driver? Did you already try reseating the nvidia in its pcie slot?

@generix Thanks for the prompt reply and my apologies on the delay. I reinstalled Manjaro again with the latest build as of yesterday. It was less buggy but I also learned that I don’t see any interrupt storms until I install the rt kernel. However, when playing CSGO with vulkan, I’m still gettin…

As a quick update: I updated to the latest beta version available from the Vulkan page ( 515.49.05), which did not help and still have stuttering during gameplay. I also installed the RT kernel again and, while it initially didn’t throw interrupt storms, I now since see that it’s throwing them ofte…

The interrupt storm is also happening with the normal desktop preempt kernel, there are just no races happening so you don’t see it in dmesg. Also, not only the nvidia is affected but also usb. After only 30 minutes of uptime, xhci is at 1.5M interrupts, nvidia at 4M interrupts. Please check /proc/…

@generix I ran watch and specifically looked at the xhci as you mentioned. Even with leaving my keyboard and mouse connected, it was not incrementing. However, as soon as I hit a key or moved the mouse, the numbers incremented, particularly with the mouse. I know that the polling rate on this mou…

@generix Here’s another debug report in case that helps. nvidia-bug-report.log.gz (1.5 MB)

I don’t really know where that’s coming from. Did you already try to reseat the nvidia board in its slot? Please also check with a 5.17 or earlier kernel, if possible.

@generix I did reseat the card and I also was running 5.15 previously. I’ll boot to 5.15 and if I get any different result, will edit this post. Otherwise, it didn’t help. :-( [cyberdeath-pc cyberdeath]# cat /proc/interrupts | grep ‘xhci|nvidia’ 16: 0 0 0 0 …

Unfortunately no, since interrupts are emitted by the hardware in general. I guess you’ll have to go the hard way, testing your components one-by-one, starting with the nvidia board. Please check if it works in another system.

@generix I tested with an RTX2060 in the same system and I get the same behavior. So it does not appear to be the graphics card itself, but still could be drivers/software. I installed the open source version as a test and also got the same behavior. nvidia-bug-report.log.gz (1.6 MB) Edit: I als…

Are there any hardware similarities betwenn the systems (mainboard, nvidia gpu model/brand)?
