Source of my computer problems identified.
Apparently the lag that’s been making art streams and drawing in general a hassle / real pain is caused by my motherboard.
Whysoslow app stated the following:
"The highest measured SM BIOS interrupt or other stall was 145 microseconds. This is considered poor behavior. Your system may have difficulty handling multimedia in real-time and may be subject to unexpected stutters and unresponsive behavior"
This likely indicates my motherboard is dying, and also explains the many weird audio glitches and other weird issues I’ve been having.
So I have a PC upgrade ahead, after that’s done and my system again can manage without horrible hiccups I’ll be likely resuming my art streams, work permitting! At least weekend streams should be doable.
