I have a question - is it possible to avoid lagframes while streaming (streaming takes up ~30% of my CPU time) ?

Otherwise my system is pretty fast, Sekiro runs @ 4K 60 FPS no problem.

And yes I noticed that Super Meat Boy visually drops frames sometimes while I'm playing. Are my speedrun attempts forever fucked ? If not what can be done ? Raising CPU priority of the game process ?

Apparently some of my runs are invalid because I had lagframes, which is super understandable, but still frustrating - I'm new to this.
