Mouse Polling

[paul2437]

I have an issue affecting frame rate and stuttering related to my mouse movement while in the sim. Any polling rate above 125 and the issue occurs. I thought this had been patched out sometime ago happens in both VR and 2D. 2D track attached with polling rate at 500.

This one definitely isn't fixed, as it routinely shows up when mouse polling is set to above 125hz. But only for some users.

I don't know of any fix other than lowering the polling rate for affected users.

Though generally speaking, some more CPU intensive games can struggle with polling rates above 1000hz. And mouse polling issues in DCS did seem to disappear for years until it's (somewhat) recent return.

Unfortunately im still having this problem. Changing polling rate affect the issue. On 1000hz fps drops to 0 when moving camera. On 500hz the camera just stuttering.

It just happens at random to me. I’ve found just Alt Tabbing out to GHUB and switching the DPI back and forth fixes it. 125 is way too clunky to tolerate.

Sometimes restarting the game solve the issue, and working just fine in the entire time.

Usually it happens to me in the first time when starting the game. Annoying "little" bug

I uninstalled DCS completely then reinstalled and the polling rate of 500 was fine. After 24 hours the bug was back. I am using an old Logitech G402 mouse I think I am missing something as the bug is random.

I would like to add some new information.

Unfortunately i have to replace my previous mouse (it was a steelseries rival 3, and its only working with 250Hz, so with 500hz its stutters).

I brought a razer deathadder v3... and in synapse i left mouse polling rate at 1000 hz... just in casem and you know, why not.

Everything just working fine, and i tested it for i dont know... 4 days now.

It seems not every type of mouses suffer with this issue.

Hi All

After a lot of testing changing to a different mouse pc settings etc the stuttering is still there until I alt tab out of DCS then go back in or come out of DCS completely and hope for the best. I don't think mouse polling is the issue I think its CPU related-what I do not know just a best guess.

It might be worth trying different USB ports on your PC.
