saindd Posted April 15, 2015 Share Posted April 15, 2015 I just started two instances of my game, one in the first monitor and another on the second, both running windowed. I did this to test some networking code, but the performance was terrible. Is this normal? I have a pretty powerful machine: i7 3.4ghz, 8GB RAM, GTX 660.

rlranft Posted April 15, 2015 Share Posted April 15, 2015 Try it with UE4. Or Unity. Should give some idea.The engine used to refuse to start a second instance, but that check was removed. I've run a dedicated server and two instances of the game on the same computer before without too much trouble, but the mission was mostly empty except for about 150 AI units.

LukasPJ Posted April 15, 2015 Share Posted April 15, 2015 Should also mention that the windows that doesn't have focus will run at a very low FPS such that the window with focus can run smoothly. I have not had any performance issues with the focused window, while doing the same thing. Quote Link to comment Share on other sites More sharing options...
rlranft Posted April 15, 2015 Share Posted April 15, 2015 Lukas is absolutely right - even if you're running a single instance and you focus Notepad (or whatever) T3D will render one frame each 100ms or so (10fps) so that you can actually do what you swapped away from the game to do. I'm sure that was added to help developers while debugging to allow Visual Studio to be more responsive. Quote Link to comment Share on other sites More sharing options...
saindd Posted April 15, 2015 Author Share Posted April 15, 2015 I have tried with Unity, since it's what i have here, and it worked well. I tried with open-source engines, like Sauerbraten and Darkplaces, and it also worked OK. I'm on Windows, btw.But, as you guys said, the problem is only on the unfocused window in T3D.
