Nice work as usual qsxcv . TY for showing us the innards, I know a lot of members appreciate it. thumb.gif

your graphs are smoother because you're moving the mouse so slowly that you're staying in the first framerate mode, so you dont get the glitches associated with smoothing+framerate transitions

sorry i forgot:
for these sensors, generally smoothing decreases for faster motion because framerate is higher. so if you use small movements and your speed remains low, you'll get more smoothing

but anyway for this mouse just use 1800 or lower and don't worry about it

@qsxcv I love you. Build Me a Son, O Lord.

Any tests of the click latency yet? I know you probably can't use the little program where you just click because razer usually uses asymmetric debouncing, but it would be interesting to know what razer's idea of "optimized click latency" is.

wonder if it's overclockable...

Hm, that's pretty useful information. I wasn't sure what to attribute the lack of difference between the setups. Running the higher dpi with no pixel skipping was very smooth, and with enough time could lead to more pixel accuracy. But for instance, when long distance sniping at high sensitivity while the lack of pixel skipping was useful, it did occasionally feel more difficult to maintain precision and predictability which most likely was a result of high dpi & smoothing at low speeds. Anyway it was an interesting experiment, but I will stick with the lower dpi settings.

Was sort of hoping with the higher sku number of the pixart sensor, they may have improved over the 3366 but just a marketing stunt re-branded or slightly modified 3360 which is disappointing...

So it has way more smoothing than the Logitech implimentation of the 3366, correct?

Probably the same at or below 1800dpi. More above that and an absurd amount at high DPI.

welp. couldn't find a smoothing register :/ so probably smoothing steps are defined in srom

for reference:

y dpi controlled by registers 0x0f and 0x0e
x dpi controlled by registers 0x2f and 0x2e

dpi is numerical value of the two registers * 50
e.g. 12900 dpi is achieved by writing 0x01 to 0x0f and 0x02 to 0x0e

so this sensor/srom should be capable of 50dpi steps, but synapse only exposes the 100 steps.
it may also be possible to get 25550 dpi on this sensor/srom
