Question / Help FPS drop in CS:GO help

[eftz]

New to open broadcaster software program. Im trying to stream on twitch.tv and play Counter Strike Global Offensive. When i start streaming i drop about 100 fps. In CS:GO, without streaming, I get 170-270 fps. When I start stream, I get 80-150 fps. When playing and streaming, you can feel the same isn't smooth. Any help would be great.

My setup:
AMD Phenom II X4 965 3.4ghz
8gb ram
GTX760 2gb
64bit OS

Speed Connection
Download: 27.5mbps
Upload: 3.5mbps

I Believe I have the right logs:

Well real time video encoding definitely puts some load on your system. You can try selecting a faster x264 CPU Preset in Settings -> Advanced or downscale your Resolution further in Settings -> Video but you'll likely have to sacrifice a lot of quality if you need the game to stay above 150 fps

Also I'm not really sure what the benefit is anyways, assuming your monitor probably runs at 60Hz

One thing you might try is right clicking the preview area and uncheck "Enable View" in "Preview" and see if this makes any significant difference.

Some people report this "lag" in CS:GO, as you describe it.

Generally it's because OBS is sharing both the CPU and graphics adapter, and because the game is rendering so fast and updating so frequently, so it's doing a lot of processing both on the CPU and GPU to be able to maintain that framerate, and sometimes OBS and the 120fps games can conflict.

• Right click OBS' preview, turn off OBS preview so it doesn't needlessly have to waste resources drawing the OBS preview screen
• Change or reduce the process priority of OBS in advanced so it interferences less with the game
• Reduce graphical settings in CS:GO
• Perhaps try v-sync in CS:GO to cap it at 120fps and to even out processing?
• Perhaps try reducing OBS' settings, downscale/etc?

Jim, I was wondering why isn't there a Below Normal priority setting in OBS?
