Not getting the performance I should

[Mystery321]

When I play Left 4 Dead 2 split screen using this tool: PC Offline Co-Op the window that is not selected is not getting a smooth 60 fps but the window that selected is.

My computer is out of the question because it's I think pretty good. My Build

Any help would be nice Thanks in advance!

You know you can use Console commands to make Left 4 Dead 2 play Split-Screen in the game client right? Anyways, it does in fact have to render 2 separate points of view and that can be taxing on performance.

Can you play 3 play split screen though? Also it should get more performance because only 20-40% is being used by my gpu

Nope, and that would probably be your issue, that's 3 Separate points of view that have to be rendered all at once and that takes a lot of GPU power. Consoles do it by lowering the Graphical fidelity everytime a new player is added.

I'm pretty sure that my system could handle it, sometimes I play split screen Borderlands the Pre-Sequel using the same tool without any problems

I suppose it really depends on the game. Left 4 Dead has hundreds of character models on screen at once.

Yeah but what I don't understand is that when I select the other window it suddenly has 60 fps but the other one goes to 17 fps?

Probably priority focus. The GPU puts more power into the most prevalent task running at the time.

Is there a way so that the power is spread out instead of just going to one task?

I'm not sure, I know that you can with the CPU using Task Manager. You could try checking around in the Nvidia Control Panel other than that you could go to Start > Control Panel > Power Options and choose Maximum Performance instead of Power Saving or Balanced.

Does the source engine have a background FPS option?  From the way you worded the issue it sounds like source is limiting your FPS on anything that isn't in focus.  WoW and D3 have a setting for this called Max Background FPS, if you turn it up or off it will render everything at max fps/v sync when the window isn't in focus
