Question / Help VR headset fps lowered when obs is running


New Member
rig info :
gtx 1080 8gb VRAM in an eGPU setup with a spectre x360 ae010tu ( i7 8th gen U series )
16gb of ram
HP windows mixed reality headset

settings: ( using obs just to record not to stream )
encoder: x264

Obs recording footage looks nice but in VR it looks not choppy but a constant lower(maybe capped?) than normal fps. here's a video showing that it looks fine in the recording
feels like the headset is usually 90fps but when obs is running its 60fps but not really sure.
Cpu never really goes above 50-60% and I don't know what can be causing it to feel like this in VR.
