I'm doing this: note my mouse and cursor's starting positions, then start making rapid and repeated circular motion (more like flat oval) with the mouse. After a while, I move my mouse back to the starting position and see if the cursor also stops at the starting position.
It seems that the result is mixed - sometimes it does stop at the starting position accurately. However, sometimes it drifts upward by quite a margin - and this is more visible in lower DPIs. Same for my Salmosa at 800DPI. Can anyone confirm this? It would be good if you can also compare with other "acceleration-free" mice too.
edit: and I'm testing this on Artisan Zero and QcK mini. Yet to test it on a hard pad like 4HD.

You're overdoing it for some odd reason. All you have to do is move the mouse linearly from one side of the mousepad to the other, noting the position of the crosshair on your screen in relation to the position of your mouse on the pad. Do 1 swipe across your mousepad quickly then return slowly. That's how you do it.

I'm overdoing this because repeated movement should "magnify" the acceleration... I have trouble stopping at the exact position in the 1-swipe test to make it accurate. But if there is no acceleration, then it shouldn't matter if I overdo it, right?

Just to clarify, you're moving your mouse in an oval shape numerous times? How are you guaranteeing that the distance traveled is the same each time?

Also, is the speed you're moving the mouse the same on each revolution or are you varying it?

The oval path cannot be the same every time, and I vary my speed (as I try to swirl it quickly without moving the cursor "off screen" - according to Enotus, it does not exceed 0.4m/s anyway).

That said, if cursor 100% corresponds to mouse movement and there is no acceleration, then the mouse should report the same counts over the same distance no matter how fast I move it. If my final position is the same as my starting position (or near it), then the cursor should also be on the same spot as the starting point (or near it).

However, the result is that sometimes the cursor will be in such a far-off position that any error in my hand position can account for it. There must be some error in reporting.

I kinda doubt that anything Roccat did could have added acceleration.

Come to think of it, the Savu is probably the logical upgrade from the G9x.

raisinbun answer is pretty simple, your test is good as long as you don't rotate your mouse.

same with the func 1030, lowers lod to something slight over 1.2 mm. But not so on the Destructor pad, where the lod remains around 3-4 mm.

The ss i-2 is awesome, but unfortunately not with the savu! In my case the lod is too low -> constant pixel skipping + low max speed (around 1.5-6 m/s). Though the Zow. AM, Abyssus, krait and mx518 (currently on my desk) perform all very well on it!

Perhaps, but have you tried it at 400 CPI at high speeds?

No acceleration. I don't know that the ADNS-3090 even has the option for doing acceleration in hardware.

Sounds like an issue with your testing methodology, or perhaps skipping on your mouse surface.

If anyones interested, that stats are definitely stored in

HKEY_CURRENT_USER\Software\ROCCAT\Savu\Statistic DB

Just back that key up if you want to sync stats between PCs.


IF you look at that key itll look something like this

"Statistic DB"=hex:86,10,00,00,d6,01,00,00,6e,00,00,00,14,00,00,00,14,00,00,00,\
70,03,00,00,ba,0e,00,00,1e,00,00,00,00,00,00,00,d4,00,00,00,00,00,00,00,10,\
fc,01,00,68,01,00,00,46,00,00,00,14,00,00,00,00,00,00,00,00,00,00,00,c8,00,\
00,00,3a,02,00,00,00,00,00,00,00,00,00,00,05,00,00,00,00,00,00,00,06,fe,01,\
00,00,00,00,00

The only think Ive bothered to figure out so far is that the first 4 hex digits (86,10,00,00,) are the number of Left clicks in hex and the next four are the number of right clicks.

If you want to play with this, here's an example so you can make sense of the numbers. Say you want to have a large number of left clicks, lets say 17555555 clicks. Pop that into a decimal to hex calculator (calc.exe works) and convert to hex. That will give you 10BE063 in hex. This needs to be split up to put it back into the original format but the smallest digit comes first. So it would be:
63,e0,0b,01

So to have 17555555 left clicks a the reg key would be the same but with the first four hex digits changed:

"Statistic DB"=hex:63,e0,0b,01,e0,01,00,00,6e,00,00,00,14,00,00,00,1e,00,00,00,\
84,03,00,00,ec,0e,00,00,1e,00,00,00,00,00,00,00,d8,00,00,00,00,00,00,00,10,\
fc,01,00,02,03,00,00,50,00,00,00,14,00,00,00,00,00,00,00,0a,00,00,00,dc,00,\
00,00,6c,02,00,00,00,00,00,00,00,00,00,00,09,00,00,00,00,00,00,00,06,fe,01,\
00,00,00,00,00

I find it easiest to export the whole key using regedit, manipulate in notepad and then import again. You must kill Savu Monitor.exe before trying to import the new data.

Not sure if anyone cares about any of this? I can go through some more of the hex and try and figure it out if theres enough interest?
