Mirillis forum

So for quite long I have been using OBS for recording/streaming because it allows to use QuickSync. Obviously QS doesn't that much FPS for ex. playing CS:GO without OBS(QS) I have around ~240 or more with recording I have about 210. And fun fact that if I use QS in Mirillis my FPS drop to around 120-150. Same happens with AVI (CPU) and same thing is with AMD VCE. What I mean is that why I have different FPS by using Mirills than OBS and why QS drop my FPS as AVI or AMD VCE does :O. I have tried different res/fps/changing bitrate/quality/recording on SSD and HDD with same resoults.

My PC:
Gigabyte GA-H81M-HDS3
i3 4160
R7 260X 2GB OC (Gigabyte)
2x4GB 1600MHz HyperX
1TB WD
120GB ADATA XPG SX930

If its very important I can make a video.

I have the same problem, we need to fix it
