Question / Help Dropped/ hitching frames while running obs, gtx1080 6700k

My specs are:
cpu: i7 6700k
gpu: asus strix 8GB gtx 1080
ram: 16GB corsair vengeance
boot device/ file location of obs and csgo: Samsung 750 evo

My output setting are as follows:
Encoder: H.264
Enforce streaming services encoder setting (enabled)
rate control: CBR
Bitrate: 500-2500 ( I have tried a range even going as far to drop the res with no change in performance.)
key frame interval: 0
preset: default
Profile: main
Level: auto
GPU: 0
B-frames: 2

While OBS is open (not streaming just open, although the preview window is working) I go from around 300 fps in csgo to 70-90 fps with regular frame hitching. My thermals are fine with my cpu maxing out at around 70'C and my gpu maxing out at 60'C. My cpu usage stays around 55-57% but gpu usage stays at 88-90% (even when I disable H.264 and use x264) and memory usage is 100% on the gpu, all 8GB. I am running the latest version of obs however this issue has persisted for about a year going through many iterations of obs updates.

Does anyone know what might be causing this? All help is appreciated.
