Question Lower fps, but nothing reaching 100% usage

[BakedPizza]

In games like overwatch I am not reaching the max fps of 300, but nothing in msi afterburner shows anything close to 100%. When I try to stream using streamlabs obs, my in game fps drops significantly.My hardware should be good enough to hit the max fps and stream. My gpu has an encoder that i should be able to use while streaming to avoid fps loss, but i still lose fps in game. All drivers are up to date and i have lowered settings in game to all low.
Any help is appreciated, Thanks.

Do you have OBS set to use the GPU for encoding?

Is your overlcok stable? remove the overclock and see if system performance improves, if it does then you have your OC too high.

Are ok for both the CPU and GPU?
