[SOLVED] Internet Throttling when system runs cpu or gpu demanding software

[Kablien]

I am having an issue with my network where my 100 Mbps network throttles to an 8 Mbps average and the worst case is that upload speed dips to 0.2 Mbps. This issue happens whenever I run CPU or GPU heavy software like Solidworks, Ansys, adobe, and even offline games.

The speed obtained during normal CPU or GPU usage:

In dire need of help for solving this weird problem.

Are you sure this isn't a result of the load on the CPU, rather than really an issue with your ISP?
Check connection speed from another device while the load is on the PC.

Speedtest requires CPU cycles to generate and receive data. If your CPU is 100% busy with other tasks, I am not surprised that your "tests" show diminished capacity.
