Hey guys,

So it appears when I use any decent video quality settings on OBS my ping shoots up 300+ ingame, (Tribes Ascend btw.)

First off I would like to point out according to speedtest.net my upload speed is pretty good.


Here is my log:

After messing around with many settings it seems like if I go above a down scaled resolution of 720x450 my ping shoots up. It's strange because it seems like that's the cut off, any higher than it just jumps, no gradual build.

I just wanna up the detail and resolution since my connection can handle it right?

thanks for any help

Lol welll after doing a bit of research I realized speedtest.net is fuking garbage!!

According to testmy.net my upload is 3.4


So i'm guessing this is prolly the issue? Should I adjust bitrate and buffer settings? What should they be?

The most relevant measurement would be to do a Testmy.net test to a server near the one you've been streaming to. That gives you a good figure of what bitrate you can maintain to that server.

Also, try the following:
  • Enable CBR
  • Enable CBR Padding
  • Disable Custom Buffer Size
  • Enable CFR
  • Set the keyframe interval to 2 seconds
It will help to stabilize your connection with Twitch and consequently may help to stabilize your ingame ping as well.
