We'll need some more context. First we'll need to know the specs to the system. Please list them like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
Second, by stream, what platform are you using to stream onto a client PC? Third, we'll need to know the specs to the client PC's as well. Might want to include videos of what you're experiencing.
