Mouse Lag While Streaming.
So, I've had like a billion different issues with Apex Legends. I've experienced weird and random crashes, sound issues, lag and all sorts of things. I have managed to solve, reduce and improve many of these things and nowadays, I'm actually able to play several matches in a row without a single crash. That's obviously good, but I have encountered another problem...
I can play Apex Legends just fine as long as I'm not streaming. I did stream Apex Legends for several days when it launched, and I never had any problems until about a week ago. A week ago, my mouse started to get these weird lags. It's hard to describe, but it's like my sensitivity goes down to 0.01 or something for a few seconds and back to my 3.0 again. Back and forth. It doesn't happen all the time, but it's extremely annoying and it seems to happen whenever I move my mouse "a lot" in a short time frame. The more I move my mouse, the more input lag or strange behaviour.
My mouse doesn't seem to keep up with my movement whenever I stream Apex nowadays, but it worked great until a week ago. I've even bought a new mouse, even though I knew that my hardware was okay... And I still have the same problems. I've never had this issue before, until about a week ago, and I've never experienced anything similar in any other game. I can stream a bunch of other games without any problems and whenever I turn my stream off, when I play Apex, I can play without these issues.
I've tried to find a solution for this, but I haven't been able to find one. I have tried all of these different "performance" tweaks out there and my game is running just fine as long as I don't stream. I use OBS.
My hardware, even though it doesn't matter in this scenario:
CPU: Intel Core i7-6700K 4.0 GHz
RAM: HyperX 32GB DDR4
GRAPHICS: MSI GeForce GTX 970 4GB
MOUSE: Razer Deathadder Elite
