Title: What's the deal with aim assist? (DPI, polling, sync)
Post by: TurboMan on 06:21 PM - 03/13/21
So I've been using the XIM for over a year, watched all the videos and read the threads, stating the following:

Higher DPI = less aim assist
Higher polling = less aim assist
Sync off = least aim assist, default a bit more AA, common more AA than default etc.


I've seen the opinions of others challenging this over time, and I've done a lot of my own testing this past month. I've consistently found some of the above to be not true...

DPI - I agree, higher DPI = less aim assist

Polling - Consistently found that 250hz polling makes the AA bubble easier to work with than 1000. Still undecided about 500hz.

Sync - Common for me makes the AA bubble most workable. In fact I have two configs that are identical apart from the sync being different and sensitivities adjusted to match. One uses common and one uses sync off. I use the one with sync off by default because the aim assist is actually stickier with sync off.
If the servers are making the AA feel weird and sluggish then I switch to my common sync config to make it feel more workable. Default is also stickier than common. Yet slow is also stickier than common and not very accurate. This is all assuming sensitivities are matched across configs (as in cm/360, XIM sensitivity is adjusted with each config to accommodate sync changing the sensitivity) and everything else being equal.


What are you guys' thoughts on this?

i agree with all of your findings except for the off sync has more aim assist that for my setup is not even close its alot less BUT to counter it i added 35 Simulate analog behaviour now i have super snappy feeling with good aim assist :D have you tried any SAB that will change all your findings again but id be curious if its changed anything for you if you did

250Hz is the native polling rate of PS4, Xbox One, PS5 and Xbox Series X over USB. Sync interpolates XIM APEX's output polling to 30,60 or 120Hz to sync the device with a game's processing loop at that frame-rate. That can result in very stick aim assist, but in some games like CoD, the aim assist bubble can be harder to pop. In those cases, bumping Response Rate to 500 or 1000Hz with Sync Off can help.

XIM APEX RR at 250Hz with Sync Off ensures that XIM APEX is polling at 250Hz to the console, which is what the console is expecting input to be over USB. That should provide more controller-like game behaviour for things like AA by using native console polling rates...at least that's always been my hypothesis.

Ultimately, it comes down to preference and few people have ever really tried 250Hz. I used 250Hz for the entire alpha-testing phase of APEX because Titan Two (also alpha-testing at the time) didn't support XIM APEX at 500 or 1000Hz. XIM4 at 125Hz to XIM APEX at 250Hz was a revelation, but I didn't find 500 or 1000Hz to be of any more benefit, while introducing things like jitter into the mix.

i agree with all of your findings except for the off sync has more aim assist that for my setup is not even close its alot less BUT to counter it i added 35 Simulate analog behaviour now i have super snappy feeling with good aim assist :D have you tried any SAB that will change all your findings again but id be curious if its changed anything for you if you did

I experimented with a script on Titan Two prior to SAB that interpolated keyboard input to take advantage of left-stick AA. Digital (kb) input ignores l-stick AA by ramping straight from 0 to 100%. But adding acceleration from 0 to 100% over say 200ms proved to be effective for l-stick AA, especially in CoD and similar games. The same effect on l-stick AA is true of SAB on XIM APEX because it uses a similar (but more complex) method to obfuscate digital input. Neither method is as good as true analog stick input for l-stick AA because you can't hold a value of less than 100% using digital input (my script also had an editable max speed cap to counter this).


Long story short -

1. for right-stick Aim Assist, I highly recommend setting mouse polling of 1000Hz, XIM APEX RR at 250Hz and Sync Off as a starting point.

2. for games with left-stick AA, definitely add SAB into the mix (I'd go with 35 or so too).

That said, I tend to stick to 500Hz and Sync Default as I can't be bothered endlessly optimising XIM APEX expert settings. I'm just not that invested in any one game and these settings feel ok for everything. I also use analog input via Azeron for true analog behaviour, so I have no need for SAB.

antithesis that is something i never tried actually 250hz sounds smooth thats the one big thing i noticed dropping down to 500hz once its way smoother. Interesting stuff for sure and the azeron must be nice with the analog stick still never pulled the trigger on one. Yeah adding a ramp up would of been a good idea its so noticable on cod how it cuts in and out when strafing SAB has helped abit with it thank god MW2019 was a aim assist cut in and out mess

can you post your COD setting/config?

I use a Nav, so no need for me to simulate  ;D

I did switch between both on BO4 yesterday and yeah, for me off sync 100% game me more aim assist. The bubble felt so sticky compared to common, yesterday was one of those days where the servers were a little weird and the bubble was feeling janky so running common allowed me to interact with it a lot more smoothly.

Off Sync does offer more aim assist. (The jitter is the key here imo, coming from using MJFame Variants for about a year before moving onto something different.)

Don't crucify me lol.

Iíve always found BO4 to have too much AA, which makes it hard to enter the hitbox or to lead a target.

Adding Steady Aim helps (XIM output is quantised), as does increasing Response Rate and DPI to help pop the AA bubble.

Yeah, MJFame 100% gives the strongest aim assist of any config I've ever used. Seems to be really popular with wrist aimers for that reason but as an arm aimer, I used it for quite a while but I just found that my ADS sens had to be disproportionately high compared to my HIP sens to be able to cut through the bubble.

See, I always used to use 0.5 steady aim and 50-60 boost on most configs running high DPI, response rate and sync off. I stopped needing to use it when dropping to 250hz and common sync. DPI kept high to cut through, 250hz and common sync just makes the AA bubble much smoother and no boost or SA are needed IME.

What dpi do you use turbo if you donít mind me asking I struggle with dpi I have a bad game and up it lol I always change my settings when I play bad

So this is a pretty old thread and I've noticed some more things, which are concurrent with other users views in this thread.

When it comes to low hz, I feel like sync off actually makes aim assist stronger than default. However, at high polling, sync off provides less aim assist. That's my experience having tried them a bunch on different recent CoDs which are known to have strong aim assist.

Top 3 configs for me are:

12,000 DPI or higher; 125hz; default sync; no smoothing
12,000 DPI or higher; 1000hz; 10-15 smoothing; default sync
900 DPI; 1000hz; max smoothing; off sync (current config)

When you apply 'smoothing', do you apply it on 'Hip' fire or 'ADS'?

Thx in advance.

Hello friend, thank you very much, your post is very good

I am CoD player (vanguard now)

In your opinion what do you think is the best configuration?
Hz of the mouse? Hz of Xim?
Sync off? Sat? Smoothing?

Thank you friend

With sync set to OFF, that means itíll run at the Hz set in Global Settings? And having set to anything else will override the Global settings, correct?

Correct.
