Bug Report Extreme mouse acceleratoin

[Ayyylias]

Hello,

I have been using OBS to stream Minecraft (don't judge :) ) for quite a while now, but for some time now I have been noticing some kinds of mouse acceleration when playing while streaming. it usually occurs when my computer is turned on for a while and my stream has been running for a while my mouse input starts to act very strange. it doesn't always happen but when it does it will usually re-occur after I restart my computer. There are barely any background tasks running on my computer and the issue only happens when I am streaming with OBS.

Specs:
I7 4790K, GTX960 (4GB), 24GB ram, Intel 530Series 240GB SSD
But I have also heard of this issue on a I7 6700HQ with a GTX960M, which leads me to believe this issue is not hardware bound.

My hardware seems to be handling the stream fine since my CPU is around 30% all the time and the GPU is around 50% most of the time. (memory is fine too of course)

The issue happens both when I stream with QSV and with NVENC (since I really fancy hardware encoding over software due to it's reduced stress on my hardware.)

I have done some testing and it happens pretty much all the time but it's a lot worse when I am holding/clicking one of my mouse buttons (it sometimes makes me spin a full 180degrees). it usually also causes a lot of frame time spikes in my game (for no apparent reason as all of my hardware seems to have more than enough headroom)

Results:
(I will replicate this issue when I am done with dinner and post the logs)

This is very hard to show on video but at 0:10 in this video my mouse jumped to the bottom left corner a bit. The issue happens both in Fullscreen and in Windowed, when in fullscreen I am using a gamecapture source to capture.

 

[Sapiens]

Enable vsync or the FPS limiter option in Minecraft and test at something like 60 FPS. Any improvement?

It seems to me that the mouse "sticks", what I mean by this is:

Minecraft picks up what movements you want to do by resetting the mouse to the middle of the screen, and when it does so it will move the mouse according to the distance it was moved from the middle before being moved to the middle again (I can show that like this:

), which is also why I think it's a lot easier to play at high framerates(less input lag and more accuracy) and it seems like it causes my mouse to be reset to where it was (minecraft sets it to the middle, but OBS sets it back to where it was )

Hello,

resolution:
I found out this was not a problem with OBS, my mouse is broken, the sensor likes to add in jumps which are causing my issues.
After 3 years of service it decided to stop working properly, sorry about making this thread before testing that.

Another issue I have found, (will also make a thread about this in the future)
I am using 2 scenes, one is for my monitor capture, the other one is game capture. When I change from screen capture to game capture the game capture will be black at first.
