    Bagged a Razer Viper. Needed more finer control than I have at the moment.

    Saw that, a bit what I expected. It's an improvement but it's not something that should decide what you buy tbh. The right shape will still impact your gameplay a lot more. Diminishing returns are kicking in going beyond 1000Hz.

    I will re-post here what I have unearthed in this troubleshooting thread
    https://forums.guru3d.com/threads/how-to-know-if-a-motherboard-has-a-usb-ehci-controller.438251/

    I was using UsbView - https://forums.guru3d.com/threads/freshly-built-version-of-usbview-utility.421820/

    There are a bunch of USB 2 ports at my home rig:
    [​IMG]

    and USB 3 ports:
    [​IMG]

    And I noticed something else in those ^ screenshots - the "Companion Port Number" field:
    - on first screenshot Port 1 (USB 2 one) specifies "Companion Port Number = 17";
    - on second screenshot Port 17 (USB 3 one) specifies "Companion Port Number = 1";
    I went to search for that "Companion Port Number" thing and look :
    https://docs.microsoft.com/en-us/wi...tl/ns-usbioctl-_usb_port_connector_properties
    So ports can share physical USB connector. I went to see other USB ports on my rig and found that ports 1 through 8 (USB 2 ones) have ports 17 through 24 (USB 3 ones) as a companion ones - so they share USB connectors (1 with 17, 2 with 18, etc).

    And some of ports has no companion ones - 9 through 16:
    [​IMG]

    and 25 and 26:
    [​IMG]

    So it can be that ports without companion ones are better for mouse and keyboard.

    PPS
    And article "why you should avoid companion controllers"

    I've been playing the dpi/sensitivity game and was wondering if there is some golden ratio from mouse to game. Like 500dpi/15 game sens (I am playing Cold War at the moment)

    No.

    There's no golden ratio and the settings you choose are usually preference. But there are some caveats to keep in mind:
    • Mice don't perform the same across their entire DPI range, there usually is a certain "golden range", but this varies from mouse to mouse or brand to brand
    • Some games are a bit dodgy with either low or high dpi (although this was a bigger issue years ago, with all the console ports)
    • When you notice visual loss of precision (unable to make very small motions without "jumping" or "skipping" pixels), increasing dpi can be helpful
    • Some older sensors really did have an "ideal" dpi which was native (not so much applicable, less of an issue on newer sensors)
    A lot of modern mice using 3360 or 3389 variant sensors will have some added smoothing (or increased smoothing) through the MCU at higher DPI's. But it varies from brand to brand, sometimes it's when going over 1600, 1800 or 2000 dpi.

    NOTE: you don't "really" skip pixels with mice as you're moving a 3 dimensional camera represented on a 2D plane (your monitor), but visually it kind of feels like it, it looks very similar, aka 1 update moves the camera for a much greater distance than a single pixel on the monitor.

    Is it generally better though to increase DPI than sensitivity if you want faster mouse movement?

    Also I guess the Windows setting 6 / 11 still stands as recommended or even necessary for 1 : 1 tracking?

    EDIT: follow up idea: would it make sense to set ingame sensitivity always to 50 % and tweak DPI instead?

    Though I guess you can never know what the ingame settings actually mean, is 50 % unaltered or 100 % or 0 %.
    I guess these should always be sensitivity scaling though, meaning if 50 % is 1 : 1 then 100 % is 1 : 2 (=same amount of mouse movement means twice the movement on screen).

    The concept of 1-to-1 isn't something that applies to ingame sens, it's merely sensitivity * (yaw or pitch value) * mouse input. There's technically some effect, but then we're really nitpicking into unecessary details.

    Quoting someone more knowledgeable then me with a far more in depth engineering background (I'm not going to discuss the person's name as it was a private conversation):

    Ideally games should do sensitivity * (yaw or pitch value) = new yaw or pitch value and then do (new yaw or pitch value) * mouse input.

    P.S. Yaw/Pitch is basically X/Y axis values for up/down and left/right.

    Thank you :)

    I'll keep using relatively low DPI then.

    I tried setting DPI a bit higher - 750 -> 1000 - and in turn lowering sensitivity a bit in Doom Eternal but it just screwed with my precision even if the overall feel was about the same.

    I'm so trained to 750 and ingame sens at 5.5 that I'll revert.

    Note to self: changing DPI during an Ultra Nightmare attempt is a bad idea...

    Btw Eternal has sensitivity setting from 0.1 to 30 + horizontal and vertical scaling as percentages.
    Scalings could be the pitch/yaw default values and sensitivity could be the multiplier I guess.

    My 2 cents is to see if you can make it work at 800 dpi. A lot of mice support steps of 100 dpi or less now, but not all of them do. Getting used to a sensitivity at 400/800/1600/2000/... removes your dependency on having a mouse that can do 50/100 dpi steps.

    Also a lot of games nowadays don't have a linear scale for the sensitivity setting (for instance 0.5 in the menu is not half of 1.0), which imo is very confusing. The only solution to this is either simply testing through trial and error, or some research online to figure out the actual code or calculation for a specific game or engine.

    Back in the Quake 3 days this was much easier tbh, pop open the console and type sensitivity x.x, scaling was linear and 1 was half of 2, etc.

    There's also people saying higher dpi has less latency, but I'm not sure if this is true. Higher dpi means the mouse is going to pick up on smaller movements on the pad, the lower latency could merely be the impact of the mouse responding to a smaller movement increment on the pad, aka it requires less physical movement to register something. This would mean the lower latency is literally just a physical interaction.

    Also, if you're somewhat jittery or unstable with your hand, not going to high with the dpi is often the better idea.

    As it happens been using 800 for a while actually.

    And I suppose whatever you set, there's no substitute for practice :)

    Picked up a Logitech G305 on Amazon for £28.99, also some Energizer AAA Lithium Ion batteries. A touch of kitchen foil to make the AAA fit.

    Best mouse ever, bar none. I'm a fingertip guy, 19x10 hands. GPW now sitting in it's box under the bed.

    Only thing i wished is all mouse would use advanced clickers that arent so loud. My mx518 is quietest out of all mice i had except g400, but havent even quiter clicker would make it the perfect mice.

    Well I guess this is the place to go for a new mouse!

    My second Logitech M220 SILENT Wireless Mouse in a row has seen the left click just die on me - become about 70% less responsive.

    So I ain't buying a third - but I DO like the shape and design.

    Can someone recommend me one very similar but with more reliability? Has to be wireless, obviously. And, I guess, preferably not Logitech.

    Thanks!

    I have the logitech super lightweight gaming mouse, absolutely love it, you are almost unaware there is a mouse in your hand, I am a gamer so was a necessity :)

    One of the best on the market atm. To bad the shape isn't ideal for me :( (to high, I like lower designs). Currently using a Zowie FK2-C.

    That's a though one. Mice of that size tend to always get the "budget" treatment from most vendors. Maybe Razer "Pro Click Mini" or "Orochi V2"?
