  • 1.  17.6.4 how to solve keyboard lags

    Posted Jan 12, 2026 08:28 AM

    it seems that i can't get rid of keyboard lag inside my w10/w11 vm's after uninstalling 25H2 and reinstalling 17.6.4

    workstation runs in hyperv mode it seems (as i can't get rid of vbs)

    already have keyboard.vusb.enable = "TRUE" in the vmx, this does not change a thing, every keystroke just comes behind the actual pressing of the key...

    any other solution i can try?

    tia,

    marc

    Does adding the following lines to your VM's .vmx file help?  It's possibly a lag in rendering and not actually input lag.

    mks.vk.syncPerEndFrame = "TRUE"
    mks.dx12.syncPerEndFrame = "TRUE"

    that didn't solve it

    went on to simply disable accelerate 3d in the vm settings AND added the virtuals keyboard.vusb.enable = "TRUE"

    which seems to solve the issue for now...in both vms

    Keyboard lag has been an ongoing issue since early versions prior to 25H2 on all my 3 desktops, not long ago I decided to clean install windows 11 on one the desktops, after the installation was complete; all software were reinstalled including vmware 25H2 and it nearly knocked me off the chair upon seeing how smooth vmware was running (No keyboard Lag whatsoever!) while the other 2 PCs remain with the usual drag. Upon closer examination on the pc with newly installed win11 I finally figured out that it has Windows Hypervisor feature turned on while the other 2 did not. Now all 3 no longer have the keyboard lag issue at all. Please try turning on the hypervisor feature and see if it solves the lag, good luck.

    if that is the case then broadcom should just mention that, but that said, i'm in the believe that hyperv is still active on my system cause VBS is running and my vm is not running in cpl0 mode

    furthermore i have ran my vm's on w10 and my previous w11 (with hyperv disabled) without any keyb lag whatsoever, so i doubt hyperv is key here to solve it... or there is some other thing in hyperv that needs to be enabled or disabled...

    just wished that workstation could handle this during setup, i'm in no way that expert to fiddle around
