I've been using DPI analyzer to match sensitivities to the 3 different computers (and mice) I have access to (Logitech G700, G602, and Perixx MX-1800B, 2 Windows 10, 1 Windows 7) and it's been working great on the same PC. However, I've noticed it returns different results on Windows 7 vs Windows 10, regardless of what mice is plugged in. I'm getting around 15% lower DPI measured on Windows 7 for each mouse (e.g. 700 DPI vs 800 DPI). I also measured cm/360 for one mouse in one game (Perixx in PUBG) and got the same values, so it appears that the actual DPI is the same, but the desktop/website receive different values. One important note is that the Windows Text affects the desktop/website sensitivity on Windows 7, and Windows 10 before the Fall Creators Update. After all this testing it seems like there is a difference between Windows 7 and Windows 10 sensivitiy, and the website is calibrated for Windows 10. Setup: All PC's have MarkC's mouse acceleration and chrome zoom set to 100% (which does affect the values the site receives). Firefox has the same result as chrome at 100%. Computer 1: Windows 10, 250% text size Computer 2: Windows 10, 100% text size Computer 3: Windows 7, 125% (default, possibly for this resolution) text size When switching Windows 7 to 100% text size, I then get 870 DPI (matches 1.25 * 700 DPI at 125% text size). I guess since I verified in-game cm/360, this is more of PSA than anything else as I did some searching and didn't see any information about it.

Hi guys. I wanted to drop by and see if I could get more input on something I've noticed when it comes to different sensors (thanks to the DPI analyzer). I have an ec1a, G403, G502, DA-elite. When testing all these mice, the 3366 from Logitech seems to be 99% accurate when measuring 1inch at 800dpi. The Ec1a and the DA elite however give me varying results. My DA-elite actually lands around 840 or 860dpi. I was hoping there would be others here who could help me confirm the actual dpi/accuracy of the DA-elite and Ec1a since I'm having the hardest time transferring sensitivities between these mice. On a sidenote, I'd also like to point out that the sensor in the G403 seems off center. When palm gripping the mouse and moving in a straight horizontal line, the mouse actually moves in a vertical downward angle something none of the other mice seem to do.
