500Hz mouse on 500Hz monitor could feel pretty nice, especially for VSYNC ON or a 500fps cap.

However, if you use floating frame rates or a different cap (VSYNC OFF or FreeSync or G-SYNC) where frametimes are no longer synchronized to the mouse, you still need 1000Hz or 2000Hz+ (Razer's 8KHz mouse, etc) to prevent aliasing effects (mouse jitter) between mouse Hz and the gametimes (which usually is more-or-less in sync with frametimes, but also gets jittered by GPU-rendertimes).

I just pre-ordered the new FinalMouse Ultralight Pro, but I found out it can only do 500hz pooling rate. Could anyone explain what are the disadvantages in terms of input lag and other perceivable things compared to a 1000hz? I use a 240hz monitor.

My 2cents on this topic...

When it comes to mouse HZ, I think consistency is far more important than merely having the highest HZ possible. You would think all modern systems should be able to run 1000hz w/ ease but I don't think that's necessarily the case. Almost everything affects mouse polling. If you were to compare a 1000hz mouse polling chart to 500hz, you will find 500hz is far more consistent than 1000hz. With 1000hz, you're going to have significantly more variance in your polling rate which ultimately affects your aim and muscle memory. 500hz works flawlessly.

Another thing I'd like to point out is that DPC latency will be higher at 1000hz vs 500hz. Now whether this is just a driver issue or just the nature of higher hz resulting in higher DPC latency, I'm not sure. What I can say is that overall system latency increases @ 1000hz vs 500hz.

You also have to consider how damn good these sensors are becoming. They pick up literally every movement, jitter,etc. This is more prevalent @ 1000hz since it's tracking more often. @500hz I feel like you can more easily control the movements, especially at higher DPIs.

If you're running Windows 11, there are still known mouse polling issues @1000hz w/ this OS. @1000hz, weird shit happens sometimes and I don't think it's fully resolved yet. So 500hz on 11 is still your best bet.

There is hourly offsite backups of Blur Busters Forums now.

Yes, I hear you there. I love 1000Hz+, I understand why 500Hz is used, we just wish more mouse manufacturers would give us the choice to choose 500/1000/2000 with their attendant pros/cons.

Is there a specific reason why mouse polling has such an effect on frame smoothness?

And would there be hopes for the future with regards to separating the dependencies on each other?

As at the moment it’s exactly as you said, low polling = more accuracy (excluding 125) but higher poll = smoother image.

So as it currently stands, you have to select the trade off you want, which kinda sucks.

can I know the setup which keeps 500fps at modern games?
