    It should not. But taking to account the complexity of modern hardware, firmware and software it can cause stuttering. Only you can estimate that on your rig. And you can always turn back.

    Looks appropriate to me. Some gurus reported better responsiveness from mouse after the set priority of corresponding USB controller into "high".

    PS I smell a Final Fantasy fan!

    Should I put all USB Controller on high then or just the one with the mouse? Could the Xbox One Bluetooth Dongle take advantage of it too?

    PS Sure am, thanks for the quick response

    Dongle can take advantage too. But I would insert it into the port connected to the same USB controller where mouse is connected - that will allow to set high interrupt priority on one USB controller. I suspect the less devices utilize high interrupt priority the more noticeable positive effect.

    If someone with the same or near the same system will notice more stuttering after setting these devices to MSI pls let me know
    Ryzen 5 3600
    RTX 2070 Super
    16 GB 3000 mhz(ballistix red 2x ddr4)
    B450 A Pro max motherboard

    I just can't tell it myself maybe its just a placebo

    You are not alone.
    My system is i7 4790, RTX 2070 and 8 GB DDR3 1600 mhz. I did some test and noticed that Nvidia MSI mode is a bit more stuttery, but the difference is nearly unnoticeable. In general legacy mode seems to be more smooth with same minimal fps. The input lag also seems to be the same (maybe MSI is a bit faster). But all these observations may be a placebo.

    Question should i use msi mode for all my devices? If i can that is.

    For example ahci Sata, asus xonar , and PCI to USB and somr other things didn’t work.

    And should my gpu and network have higher priorities in msi tool? I noticed more stability from what I think is this. Before I only had my gpu in msimode but with all I don’t as much of FPS drop when
    Moving mouse in CSGO as before.

    You should use MSI mode for all devices which are capable of and which do not glitch in that mode.
    As for higher priorities for GPU and NIC you can experiment yourself. Theoretically NIC in higher priority can give you a bit of improvement in CSGO network stack.

    Thanks man for answer.


    So higher priority is more stability?

    I can’t set my sata to msimode, i come to the windows flag when I reboot and it never boots. Would it work if I install drivers for sata? I have Asus v gene


    And if your playing competitive gaming I always heard that usb 2.0 is better for responsiveness. But is it better than 3.0 in msimode? Asking since i read on a other site that 2.0 can’t do msimode. Is that correct?

    So there is no way to get it in msimode then I guess.

    About the usb 3.0 MSi vs 2.0 usb it got both better and worse :p

    Not stability. Mouse and keyboard should feel less laggy.


    If you use Windows 7 then you can install Intel RST drivers v11.7.4.1001 from here https://www.win-raid.com/t2f23-Intel-RST-RSTe-Drivers-latest-v-WHQL-v-WHQL.html.
    I don`t know why Astyanax wrote that RST SATA drivers do not support MSI mode, because I used them myself back in Windows 7 days and they work in MSI mode by default.


    USB 2.0 do not support MSI mode. Which ports are better for competitive games you can decide for yourself by testing. I do not game competitively, so I don`t know.
