How to limit gaming speed?

[Caleb]

I have a simple problem and hopefully it has a simple solution. I want to limit the speed for an online game, namely Roblox. I edited the line under if (m_SimulateModem), which works great for webpages, but it didn't slow down the game. Is it possible to limit the speed for online games using Fiddler? I believe Roblox uses UDP for communication, so can I edit something to slow UDP communications?

Hello Caleb,

Fiddler is an HTTP/HTTPS/FTP web debugging proxy. That said, Fiddler does not capture traffic that goes through UDP, and you could only capture/modify/debug traffic that goes through one of the listed TCP protocols.

Well, that's unfortunate that I can't use Fiddler to do that. Thanks for answering, though. I appreciate it.

That's what I'm wondering as well, but with this explanation it doesn't seem possible to do it.

Based on Nik's answer, it all checks out: fiddler only slows down http/https, but it just doesn't see the game's udp. I also tried simulate modem just for the experiment and saw that extremelightningroulette.org in a separate tab really started loading slower, but the actual game session didn't change. Same thing with red-door-roulette.com, the pages react to the delay, but the real gameplay doesn't. Looks like if you want to limit speed specifically in games, you'll have to do shaping on the system or router level, not through a proxy.
