Surface Tuning.. - Page 2

post #11 of 22
Not sure would be nice if Logitech told us, it certainly does more than just adjust the LOD. I do use it though, factory default always feels like crap for me
post #12 of 22
this info comes from what i learned during the "reverse engineering 3366" thread and a 3360 datasheet. i'm not speculating; i'd make it clear if i am.

squal means "surface quality". it's supposed to be related to how many trackable features there are in the image the sensor sees. when you lift the mouse, the image gets blurred so squal decreases. that's how lod is affected

You can create a custom surface tuning profile, then you can edit a cfg filie and change the squal threshold yourself and then restart LGS and reactivate the profile. Best make sure you have a second mouse on hand just in case, unless you're extremely good with keyboard shortcuts.

I'll give you a hint:
0 is the highest LOD you can set, and you can't go higher than factory default. At least not with the config file or any sort of calibration anywhere.
The pixel thing can have an effect on when tracking stops.

I completely forgot what I tested, but I went around changing the squall until it "barely" tracked then raised the pixel thing until it didn't track at all.
Then I tried to go backwards but the most I could get was the same LOD as factory default. Then I realized I wasted my time.

Please don't ask me any questions about this as I don't remember anymore. You can create your own tuning profile then edit the CFG yourself and mess around and see what happens.

It's somewhere in users/xxx/ in one of those folders. I don't remember where. It has the name Logitech in it, though!

About this surface tuning thing..

I bought a G640 and I currently have a G502. When I use the surface tuning preset for Logitech Cloth Pad, my mouse stalls in Overwatch depending where I move my mouse on the mousepad.

However, it does not seem to happen in other games or even on the desktop.

Default works fine or if I tune it myself...

Why is that? Could it be caused by the Tiger mousefeet that a bit, maybe a bit taller than Logitech's original feet? But then again, why do I have this problem in Overwatch but not in Diablo 3, Desktop or League of Legends?

tl;dr: Logitech's built in G pad defaults are not accurate.

Because diablo 3, league and the windows desktop are 2D perspective games controlled on a flat plane.
You require far less mouse movement to go from the left to right side of a 1080p or 1440p screen window on a 2D application, than making a 360 degree turn in a 3D FPS game, unless your sensitivity is set so high that the game is basically uncontrollable. Far more mouse movement is needed for a 360 degree turn.

Try setting the overwatch mouse sensitivity to 10 and your DPI at 1600 then you'll see the problem "disappears". But anyway, don't use that tuning option. You're getting tracking errors and overwatch is picking them up since more movement is needed. Just use default.

Logitech's default tuning settings are clearly not accurate.

Wait.. how does the surface tuning settings affect DPI ?
