Question / Help Quake Live frame rate issue

[Scorch_]

My over all goal is to reach 125 fps given the fact that quake live is not a super hardware intensive I figured this would not be much of an issue but when attempting to stream quake live my in game fps bounces between 114 or 117 and sometimes 121.

I had originally thought that this was due to incorrect settings but even after doing some reading and tweaking my settings some more the problem remained. Then I got to thinking maybe the issue does have to do with hardware limitations but even after downscaling my stream resolution to 640x360 the issue persisted.

At this point being rather new to streaming and having no one to turn to I'm all out of ideas and was hoping I could get some advice as to whether this is because of hardware limitation or because I'm using the wrong settings any and all help would be greatly appreciated.

Here is a copy of my log from one of my attempts streaming at 1280x720 if needed I can also post the ones from when I tried streaming at lower resolutions.

Quake Live may not be resource intensive relative to other games, but streaming certainly is. If you are in an environment where you are extremely sensitive to FPS drops, you should look into getting a 2-pc setup so that the streaming doesn't affect your gameplay.

If you're willing to sacrifice image quality to gain system resources, you can try streaming at the superfast or ultrafast presets. Your quality will noticeably suffer, but it might ease up on your system enough to gain those precious frames back.

Thanks for the info and the quick reply not to go to off topic but any chance you could point me in the right direction where I might find more info on a 2 pc setup.

There's some info here: viewtopic.php?f=18&t=2021

Basically, the idea is that you have 2 computers: on one, you play your game as normal, and on the other, you have a capture card that can capture the video and audio produced by the gaming computer. Then the computer that is capturing everything streams what it is capturing. So the encoding/streaming process is all done on a separate computer so that your gaming computer is not affected by the encoding at all.
