[Feature Request] Set Message-Signaled Interrupts

[chrcoluk]

They dont do this unversally, for years now my Nvidia GPU has defaulted to MSIX.

futile exercise.

Yeah, definitely. That is why the NVIDIA forums are filled with people having problems I never experience, every time a new driver comes out.

My RTX 2070S on Win10 has MSI enabled but a positive IRQ, so the "negative IRQ == MSI enabled" correlation no longer seems correct.

What do you see in Device Manager, when you open the properties of your GPU, go to the Resources tab and scroll down?

Is your GPU sharing any PCI-E lanes with anything? (Running 8x mode)

Nope:

Some new things showed up in the MSI utility for me. They were never there before (I haven't changed any hardware).

All seem related to the PCI Express controller. It doesn't list supported interrupt modes for them like it does for the other devices. What do you think about that?

uninstall the drivers corresponding to those devices and reboot, windows will install its own and should not flag them with the treatedaspci type which causes them to appear in the tool.

Hi all,

I've got a fresh Win11 install, new build 5800x3d + 4090 and it shows this device manager. Does this mean it's using legacy instead of MSI?

I'm not experiencing massive issues, just the odd stuttering on a few games but I'm not sure if that's down to the games themselves (unoptimized) or the cpu bottlenecking for example? Would it be worth changing the 4090 to MSI with the MSI util? Is changing that a case of "could hurt something" or couldn't really hurt to just change it?

Changing that setting shouldnt hurt anything

Do you have ReBar enabled?
We have other threads you're better off asking for help in, sometimes its just as simple as the CPU or VRMs are overheating and you get better performance from lower settings, PBO on and boosting an x3D is a bad idea - you want to undervolt them instead

ReBar is enabled yes. Definitely not overheating, CPU is boosting to 4450 on all cores under 100% load, CO -25, fully stable, never goes above 70C. Ram is at XMP 3600CL16.
I'm not having major issues or anything mind you, just noticed on a few games, like RDR2, Plague Tale Innocence there's a couple of micro stutters occurring but not sure if those are the game engine's fault.

That's why I was asking if enabling MSI is something that could hurt or at worst just not do anything at all.

Seems like it something else that is not software related but more hardware related. The thing is you expect too much from a hardware level to have no stuttering in anything. Learn how to accept it.

Look at my point of view that I'm running Xeon X5675 with Evga GTX 1060 6gb SC either I overclock or underclock the system it is bound to have a stuttering issue either in software and/or hardware. Sure I accepted the fact it never going to be 100% perfect in any situation than let alone 4090 that I don't see the point in buying not for another 10 years

If you havent altered your SoC voltage, you could be getting issues related to the infinity fabric at that RAM speed. They can show up as errors on the PCI-E and USB buses, so it can cause driver crashes, mice dropouts, etc.

I needed SoC 1.15v for 3600 with my 2x32GB setup (two dual rank sticks) or I had USB dropouts (most notable with my mic which would suddenly be muted, it's default just powered on state)
My 5800x in the exact same setup would get PCI-E dropouts resulting in Nvidia driver crashes, while the x3D seemed a lot more tolerant and just had USB issues.
(My 3700x gets the PCI-E dropouts above 3200 regardless of voltage even with two single ranks as an example of how older ryzens were more limited)

This is where it really helps to fill out your system specs in your user profile, as hunting back and forth through posts means no one knows your complete setup - the information you provide led you to the conclusions you've already had (that didn't solve the issue) so the odds increase that it's something you didn't think mattered (like how many ranks of RAM you have)

I just filled my system specs in. Thanks for letting me know.
I literally just enabled XMP.

Didn't touch any voltage, only CO to -25 which is stable. I have no WHEA errors, at least haven't seen anything on HWinfo.

All core load boosts to 4442, never seen it higher than that. Temps are never above 68C. CineBench R23 Multi score ranges between 14900 and 15100

I did find something out though. I noticed that when my webcam was connected to usb, this trash I bought at the start of lockdowns ( Webcam HD 1080p ) my mouse would stutter like MAD. So I'm just gonna buy a logitech one or something but regardless, those games I mentioned, I play them in my living room connected to my LG C9 (no webcam there).

Port Royal Stress Test passes with 99.7% and Time Spy Extreme at 98.6%. CPU never downclocks, neither does GPU core.

I'm just starting to think it might just be those games tbh

As I said it stuttering due to timeframe related issue like your webcam is 1080p capable maybe 30hz or 60hz during capture or streaming you have to use Rivatuner to limit the frames it the same in games in order to get it to run smoother I rest my case here
