Zowie releases EC1-A and EC2-A - Page 139

post #1381 of 2813
the mouse is fine at either setting. your system has a bit of jitter (10s of microseconds)

for anyone who thinks the 500hz pictures looks more stable:

this is not the correct way to look at things.

jitter/small scale stability should be measured in units of time.
in mousemovementrecorder (or whatever) the hz value is actually just the inverse of the previous polling period. actually this number is pretty meaningless as frequency isn't well defined when you're just considering one interval.

so seeing a 994hz in mousemovementrecorder actually means there was a 1.006ms polling period which is 6us off the perfect value of 1ms.

now for 500hz/2ms polling, if you have a 2.006ms polling period, mousemovementrecorder would show 1000/2.006 = 498.5hz so 498 or 499hz, which looks a lot closer to 500hz than 994hz does to 1000hz

Yea that's what I thought. I've skimmed through that other thread but honestly it's kind of above my knowledge level. Is there anything I can really do about the jitter? My system is pretty bare bones at the moment. In fact it got a full reformat about a month ago. I don't know how much difference that makes though.

Another thing I want to mention is the fact that while using the 500hz setting on the mouse, I get better results for both precision and smoothing in Enotus Mouse Tester. This is another reason why I've decided to just leave it alone. All in all I haven't had any issues while gaming with this mouse, and it's been performing wonderfully.

Could I test USB 2.0 vs 3.0 in the same matter? I've noticed my mouse feels a lot slower when using USB 2.0.

I think you should as I'd be interested in the results.

I imagine it wouldn't matter so much as it should be down to what the computer can process, right?

i think quite a few people have found that disable cpu c-states and other power saving stuff in bios helps.
no idea how noticeable changes in this are. haggard suspects that any jitter is magnified in actual game situations, which seems reasonable, but still we don't know by how much.

enotus is really kind of outdated/inaccurate.
precision should not be affected at all by 500hz/1000hz. remember that measurements have error.
smoothness doesn't really mean much. it's not really fair to compare 500hz vs 1000hz results. you can sort of use it to compare two different mice, both at 500hz or 1000hz.

I'm not exactly sure, was hoping @qsxcv could shed some light on that subject. I really don't know how or why, but USB 2.0 feels slow on my computer. My USB 2.0/3.0 ports are native as well.

what prompted you to notice that?

So....My ec1-A arrived yesterdasy after trying the ec2 wich was too small for my hand.
It feels good in the hand...not fully palm grip because i have la 21 cm long palm.
The same sensor wich i allready tested in CsGO, is stable but i think i need more time with it to acomodate.
I have a intelli 3.0 wich has moded sleeve cable and a suit made from carbon fiber foil.
The mlt04 feels for me the best sensor, maybe is also placebo, in fact i am thinking to swich the sensors (to put the mlt04 inside the ec1)
Did anybody try it??...because i am not so profi, i know to do sleeve and micro swich changing....

I wasn't basing my opinion on any of those measurements, but by simple desktop feel, making quick movements and making slow movements. I noticed this that I performed better at 500 hz on all mice but g303 and g402. My moves were way more stable and natural.
I realize this is subjective, but i've seen this confirmed all over. Especially on the 3090s. I've discussed this with woll3(playing in the same team) and he was also saying that on most 3310 the use of 500 hz was preferable. The funny thing is I've always used 1000 hz and suddenly 500 feels more natural.

Still, bad implementations perform worse 10 times out of 10. So, how do you 'force' a constant 1000 hz on the usb port making the mouse respond more consistently? I believe even if you fix this, it's still down to implementation, which was my original point. I don't know how to explain technically since I'm no hrdware engineer, but I can definitely feel the difference. Again, I admit this is based on opinion, so I'm not pulling a MaxK here (huehue).
