Need clarification on low DPI vs high DPI. - Page 6

post #51 of 128
Well the above is correct helps make sense of it more - but then it comes down to preference thumb.gif
post #52 of 128
I still don't see how anyone could "confuse" sensitivity for speed. We're literally talking counts/dots per inch. Number of counts. Per inch. Where would "speed" even factor into that...

speed is a factor if you look at the CPI in relation to polling rate, and that is what most people don't take into account in this whole low vs. high dpi debate.
with higher CPI at the same polling rate you can move your mouse slower to fill its buffer and therefore get consistent polling latency at lower speeds.

400CPI 500Hz 1.25inch/s
400CPI 1000Hz 2.5inch/s

800CPI 500Hz 0.625inch/s
800CPI 1000Hz 1.25inch/s

1600CPI 500Hz 0.3125 inch/s
1600CPI 1000Hz 0.625 inch/s

imo, thats the reason why many people think that higher CPI is more precise. i personally could never play with 400CPI @ 1000Hz because for me it just feels inconsistent at slow movements.
maybe, just maybe, thats the reason why so many like their wmo/mx518 if not set above 125Hz thumb.gif

People don't like the WMO and such set above 125Hz? That's news to me.

While the rest of your post is true this is misinformation. Sensitivity at default is just the default value, it is no better or worse. It's all preference. I prefer not to have too low or too high a minimum turning angle. There's a sweet spot where aiming just feels stable. To me 400 CPI at 1.6 is much better than 3200 CPI at 0.2 although both come to the same cm/360.
The default sensitivity is just a multiplier of the m_jaw.

Because it's a multiplier of your hand speed. If you move your hand 1"/s at 400 CPI you move 400 counts/s (or 400 pixels/s in 2D). Sensitivity then multiplies that with the angular rotation/count, so at sens 1 on source with m_yaw 0.022 you get 8.8 degree/s.

that's not what i meant.
there are alot of people out there who doesn't even know what polling rate is and are using their wmo's at default 125hz. then they switch to a mouse with higher default polling and wondering why it feels not "precise" anymore.
i have nothing against the wmo. i probably bought over 10 of them in my life rolleyes.gif

On mobile, can't edit previous post but:

What??? There is no relation of polling rate to speed at certain CPI levels.

so, ure telling me haggard spreads nonsense? have u ever moved your mouse slowly in any mouse tester? did u get consistent polling?

By the way, that also means that with higher polling rates (and lower CPI respectively) you additionally increase the speed at which you have to move the mouse before average polling latency occurs on every poll. For example at 400cpi @ 500Hz you hit 1ms average latency on your inputs at 500 / 400 = 1.25inch/s, whereas at 1kHz the average of 500us latency on your inputs is met only at 2.5inch/s.

This is true but the post you quoted was talking about consistent polling latency, not cursor speed.

No, but you used Haggards calculation out of context, he says 1ms polling latency at... while you just state
Quote:
400CPI 500Hz 1.25inch/s
400CPI 1000Hz 2.5inch/s

Also polling is consistent at low speeds, the mouse just doesn't send enough packets for the report rate to be higher. I won't say if can't influence feeling, but I believe that most of it is placebo and much more dependent on the sensor than the polling/report rate.
