I do networked game development on Windows and I've found the clumsy program to be very valuable to simulate adverse network conditions. You can set it up to simulate arbitrary network latency, packet loss and so forth.

You can use the tc command from the netem package for those wondering how to achieve this on Linux. https://man7.org/linux/man-pages/man8/tc-netem.8.html

I've used `tc` about three times in the last 15 years. Every time I have to relearn it.

+1 for clumsy On Windows I've also used Heavy Load, Netlimiter for more fine-grained control and Microsoft's Driver Verifier.
