dx11beta - Mouse & Keyboard intermittently stop working

Hello,

I seem to have issues while in game with my mouse and keyboard not working very intermittently. This only happens when I use dx11beta as opposed to dx9ex. Very strange problem and the only way to get my mouse and keyboard back is to unplug/plug them back in. I've tried running the game as admin and set compatibility modes for win 7/8 with no luck. Once I switch to dx9ex for video options, my problem goes away.

Game installed on SSD

I don't mind using dx9ex as a workaround, but framerates are SIGNIFICANTLY better using dx11beta.

Hey I had this same issue with my headphones recently. Try doing a rollback on keyboard and mouse drivers if they have been updated recently. Worked for my headset. Not sure it will work but something to try. :)

I found a workaround to keep dx11beta working without disconnecting my mouse/keyboard. I disabled Multithreading as well as Post Processing. After doing so, my mouse and keyboard no longer "lose connection".

I have the same problem but it started right after the mouse got connection problems. I think it's either a problem with the mouse or more likely the USB slots because it's not only a POE problem for me. But it seems POE is the only program that prevents the mouse and the keyboard from reconnecting so sometimes they completely stop working. And when I disable Multithreading the game starts lagging a lot :/

Does the workaround still work for you?

Yes, it does still work. I had to disable multithreading and post processing though. Did you try both of those?
