    WPA.exe - cursor lagging like 30 fps (after reinstall)


    Hello,

    I have an extremely weird issue as usual. I had some .Net Runtime error 1026, while I had no corruption, except that 1 error in Event Viewer. They weren't able to help on MS forums as usual...

    Problem: I installed ADK and when I opened WPA.exe: cursor would lag like 30 fps and program would close shortly afterwards. I could install programs, but I noticed on other MS installers like: Windows SDK, or driver kit, that my mouse lags like 30 fps as well...

    Here is what I tried: https://answers.microsoft.com/en-us/...9756874&auth=1

    I reinstalled computer since: and to my surprise again: when I opened installer (ADK) mouse cursor lagged again like 30 fps during install and after I installed WPA and WPR. It is called Windows assement kit - I think. I used adksetup.exe. So now when I open WPA: cursor still lags like 30 fps, but it launched at least...

    Still it does look like some important issue! Nothing in Event Viewer now and no corruption again! This was clean install of Windows 10 Pro 20h2 x64, I verified SHA of the ISO! And it is original install. No idea how this issue can persist after install... Also no problem with hardware and disk on which it is installed is fine, which is also a system disk. Other disks SMART sucks, even health is reported as good, but I had no BSOD, or any issues lately. Otherwise I have no problem with any other programs, only MS ones!!!

    I used WPA before and I don't recall it would lag. Maybe some update? I downloaded only 2 updates from February: 1 critical and 1 security. On askwoody.com defcon was only 4, so I Am not sure. I don't see what it could be. So strange! I don't care about lag, but it could be some serious issue, don't want to spend time setting up OS, which could be fundamentally broken...

    Thanks for any help!

    A couple of things, are the USB/ WiFi/ Bluetooth drivers upto date, depending which sort of mouse you use?
    Is mouse acceleration on or off?
    Is the mouse cursor being displayed using hardware cursor (normally this is only an option for cursor rendering in some games)?
    Are you using any peripheral utility software (such as Logitech, Razer mouse/ keyboard utilities)?
    From first thoughts it would seem to be an issue between the .NET framework and the cursor rendering, what or how is to be figured out.

    USB drivers are pre-installed by Microsoft. I got version: 16/11/2020 from Intel. There are none even from manufacturer. Always used these fine!

    Don't use Wifi, nor Bluetooth!

    Yep, mouseaccel. is off!

    No idea, if it is displayed using hardware cursor. This is program in windows. WPA - WIndows Performance Analyzer, it is part of ADK.

    No mouse drivers are poorly coded, except Logitechs. I avoid this by a mile!

    Issue is exclusive to Windows ADK, driver kit, Windows SDK. So doubt it will be anything above mentioned!

    Strange is there is no .Net Runtime error this time and clean install. No corruption, nothing!

    Ok, does the issue persist in safe mode, that is of course assuming the driver kit utilities will start in safe mode.
    Do you have a different mouse you could test with?
    Do you have a 3rd party mouse driver installed (some manufacturers install a .sys or .exe as a resident service for their mice to allow for custom profiles, lighting etc)?

    I was speaking about WPA currently, but it was also happening, when I opened driver kit installer.

    Yes I can test with different mouse, but my mouse is fine otherwise. I think there is 99% chance it is not a mouse!

    No I used Sledgehammer, before I connected Windows to the internet. I have no drivers for a mouse, not under mouse, or HID devices! In device manager. And I know what drivers my mouse manufacturer installs, so I would notice, if it did.

    I will try both of these in 10 hours, but I doubt this will solve anything

    I am not suggesting that the mouse hardware is at fault, I am suggesting there may be an issue between the .NET framework (which I believe the MS SDKs rely on) and the display/ rendering of the mouse cursor.
    I find it hard to believe you have no mouse drivers installed, how is Windows displaying and moving the cursor without some form of driver?

    You should have something akin to the above image, my system uses the Windows built in mouse drivers. If you have no drivers (which I still think you do have) then that could be the root of the issue.

    I don't because I used sledgehammer to stop automatic windows/driver updates. To prevent crappy drivers to install, which cause input lag!

    Yep I have these from picture and also microsoft's for HID devices. Which are contained in Windows installation.

    Okay so it doesn't lag in safe mode it seems. But safe mode is only 60hz!!! It doesn't seem different when app runs, but it hard to tell. For me 60hz looks like 30hz since I am used to 144hz monitors... Yep it doesn't happen in safe mode. Using standard boot, it also flickers (only in program window) and it looks even worse, cursor lags even more than in safe mode!

    Do you have G-Sync enabled? If so is it set to operate for both windowed and full screen mode?
    The fact it doesn't lag in safe mode does seem to point to a driver conflict/ app conflict..... it could be a certain dynamic service that WPA loads in order to log tracing causing an issue with cursor display/ mouse tracking/ mouse poll rate.
    Maybe use a combination of Autoruns and Process Explorer to determine what is happening at the point the cursor starts lagging. Process Explorer I believe has a log at start up function and some very detailed filter option.
    You could also try Latencymon to see if that can identify anything of interest.
    Sorry if this seems a bit of a rambling method, but I don't have your system in front of me and I am working through it as if it was my system, slow but methodical.

    HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA

    That was a good one!

    I didn't realize that, I used G-Sync only in Fullscreen mode. But since new MPO overlay, I switched it to both Windowed and Fullscreen mode. I have only problems, I doubted it would be that easy. I was afraid it is some complicated issue, since last time I saw that happening in connection with .Net Runtime error. But flicker and 30 fps were a coincidence. How funny!

    I don't know why G-Sync does flicker. I have luckily flicker only when games are loading! But no in-game. Someone asked me in other thread about this lately, his G-Sync flickers in game: How to verify Fullscreen Optimizations feature is off?!

    I have also one problem, sometimes there is colorless horizontal line, luckily again it seems to happen only in menu. It looks like monitor timing issue. But I read this is normal for G-Sync.

    Thanks for help BTW, I was so annoyed!

    I have a feeling the flicker is due to buffering and changing refresh rate when switching from one app/ window type to another. The problems arise because you have Windows, PCI bus timings, GPU drivers, GPU hardware, CPU, Monitor, App/Game.... and so on, all doing their things, at any point in the chain there could be an issue, timing slightly off, implementation of standards differing (Freesync, G-Sync, variable refresh rate, monitor timings, HDMI/ DP cables). When it all works it is fine, when there is an issue trying to pin it down is like wading into a murky swamp looking for a rusty pin.
    Glad you got it sorted.
