Increasing mouse poll rate info, and question....

[Gray_Area]

I have two USB mice in my system: spinner, and wireless keyboard/mouse combo.

I'm using the Mouse Rate Switcher to change the polling. Why isn't the mouse in the combo not also affected? (I don't have hardware-specific drivers installed for it; maybe I should go that route?)


I also wanted to increase the polling on my PS/2 port, where my trackball is connected. In Control Panel>Mouse>Hardware>click on PS/2 entry in list>Advanced Settings, there is sample rate. It's max is 200 - which translates to about 172 in actuality.

There is also an app for this, listed HERE for example (which I found at the top of a GOOGLE SEARCH), but it offers the same value range.

Didn't even know this was an option.

Just read through some of the info on doing this. Ugh. You have to do it for each port that the mouse is attached to? Move the mouse, redo the steps.

that kinda stinks.

But the bigger question is, does it really make much of a difference? I guess I've just never noticed any issues with spinner or trackball games, but then most of them it's been 20+ years since I've played the real things....

Would this apply to MAME which uses a low level method of reading mouse hardware called Raw Input?

Based on what I know about RawInput (which granted is not very much) it seems to still sitting above the USB drivers which is what all the "poll rate adjustments" that I saw were altering, so I'm guessing mame would be effected.

But that's just a guess. Still, I wonder just how much effect it actually has on playability.

This came to mind last night. I don't know.

Eh, just pull your machine out for the exercise.

Ideally, it's supposed to equal smoother, more graduated movement. I'm not sure, in actuality. In older versions of MAME, the car in Pole Position hardly 'drifts'; in newer versions, it does constantly. If the reason is emulation accuracy, there may be a need for greater data rate, which greater polling may address (though, a 500ms polling doesn't seem to help....).

I wonder where to find the polling rate of the original hardware?
