There's not really any 'fixed bandwidth' tests like you're describing available in Flent, no. You could perhaps simulate it by putting a shaper on the network interface of the gaming PC enforcing the bandwidth, and then just running a TCP test. The traffic won't look like gaming traffic, but you can get the bandwidth you want, and you can still measure the impact on cross-traffic on that traffic... -- You are receiving this because you are subscribed to this thread.

There's not really any 'fixed bandwidth' tests like you're describing
available in Flent, no. You could perhaps simulate it by putting a
shaper on the network interface of the gaming PC enforcing the
bandwidth, and then just running a TCP test. The traffic won't look like
gaming traffic, but you can get the bandwidth you want, and you can
still measure the impact on cross-traffic on that traffic...
