P: Brush lags with hi-dpi mice, smooth with trackpad

A client of mine had reported this earlier and I thought it couldn't be possible, but just tested it across machines and it is easily replicable. Working with high resolution images in Camera Raw, the adjusment brush lags several seconds behind when using external mice, switching to the trackpad on the same operation (without closing the file or removing the mouse) works smoothly. I'm guessing it has to do with the polling rate and spacing that is normally adjustable in Photoshop.

    Since I have a new Macbook Pro M1 (2021) two tools in Camera Raw are very slow.

    The brush tool inside the mask-tool and the retouch-tool (in German Makel entfernen).

    In Photoshop all tools work fast, but not in Camera Raw.
    What can be the problem?

    Try resetting the Camera Raw preferences:
    Hold down the Command key and select Photoshop > Preferences > Camera Raw (macOS) or hold down the Ctrl key and select Edit > Preferences > Camera Raw (Windows).
    Click Yes in the dialog that asks "Delete the Camera Raw Preferences?"

      How big a raw (and can you perhaps provide one to test via Dropbox or similar)?

      What brand and model of external mouse?

      Logitech G600, it is a high dpi, high polling mouse. The problem is not surprising, it is the same issue as having too small a spacing percentage on regular pixel brushes in photoshop, it is trying to draw too many over a short period of time. Since there isn't a spacing setting for camera raw, it would be good for it to scale it automatically (or offer an option)

      Sounds like maybe a Logitech issue but I'm wondering if you find any difference in speed disabling the GPU in PS prefs.
