Thanks for your thoughts, but I'm sorry I am a noob, and I don't understand most of your comments.
I'm streaming shows on Stremio, I select 1080p feeds and each has latency. I checked the System Monitor and the CPU is pegged at 100%. As I understand it the graphics are integrated with the CPU. My hope was that if I got a decent video card (such as AMD Radeon RX 550) that would take enough of the load to eliminate the lag. Is this a good approach or is this pc just too old?
