Metal Hawk Posted May 12, 2013 Posted May 12, 2013 Although there are many threads about the FPS problem that connect it with smoke effects and what not, I think I have found another thing that causes Low FPS. I have noticed that if I (for whatever reason) use Alt+Tab to the Desktop and back in the game, I have FPS impact. Mostly this happens in multiplayer and rarely in single player (but I still have Low FPS in single player. Just not that much.) I don't know if this is common to anyone else but I thought that it may give the developers an idea as to where to look. If it's only me, just ignore it.
Mistermann Posted May 14, 2013 Posted May 14, 2013 Hawk Yeah, thanks for posting this. I am a veteran Newb getting back into simming and your post saved me some serious frustration. :thumbup: I've been struggling with some driver issues (Saitek) and an aging PC, but finally managed to get DCS and FC3 installed and running on my machine. During all my configuring, I was alt-tabbing between DCS screens (setup) and my browser/internet. Normally I don't atl-tab out of a sim, but I was "only configuring" things so I didn't really pay much attention. Sure enough, I try a Fast mission and my once "decent" FPS went to what felt like negative! I'd give full right aileron and the control surface wouldn't move for about a 2 count. :joystick: I came here and saw your note. Of course! Alt-Tab is the culprit. I should know better. So much to relearn.

Megagoth1702 Posted May 16, 2013 Posted May 16, 2013 [...] During all my configuring, I was alt-tabbing between DCS screens (setup) and my browser/internet.

Sure enough, I try a Fast mission and my once "decent" FPS went to what felt like negative! I'd give full right aileron and the control surface wouldn't move for about a 2 count. :joystick:[...] Please note that DCS has 2 main programs. The "launcher", which is used to configure settings, create missions, select training & campaigns etc. and the main "dcs.exe" which is the simulation. When you select a mission from the launcher and hit "go" or "play" the launcher.exe gets killed and the DCS.exe is launched. This means that whatever alt-tabbing you have done in the launcher does NOT affect DCS.exe at all. Only if you start alt-tabbing while the sim is already running (you are in the plane etc.) it will affect the game. A way around that is disabling "fullscreen" in options. The game will then run in a fullscreen window, you get NO seams but you have no alt-tab issues whatsoever. No disconnects during multiplayer and something to do (browsing etc) while the game is loading. Give it a try. There is a small chance of the overall performance being a bit worse than fullscreen but I do not see 1 frame difference. Might be my good PC or maybe there IS no difference. But it's what I heard. Give it a try. And dont't blame alt-tab in launcher for bad dcs.exe performance.

Metal Hawk Posted May 16, 2013 Author Posted May 16, 2013 DCS is not the only program that can/needs to be configured. I noticed the FPS drop Alt+Tab is causing in DCS performance when I was trying to configure Teamspeak's volume. And I assume Mistermann was trying to configure Saitek's profile or something. Just because you don't Alt+Tab in-game that doesn't mean that other people don't. Since Alt+Tab gave more than one people trouble then surely there must be something wrong there. And because it's something that is not so obvious I think that threads like this can really help people. Don't you?
