[D3D11] Windows key or Alt+Tab = 2 FPS

radionaut

if anytime during the game i press either the Windows key or the Alt+Tab key combination, the game doesn't minimize as it should, and the framerate drops down to 2 FPS.
the only way to get it back to normal is by pressing Alt+Tab again. while it's 2 FPS, the windows mouse cursor shows up in the foreground (upper-left corner of the screen).

Fyi : The only method currently officially supported and without issue is dx9 fullscreen.

I assume you are using dx11 windowed?

I would imagine he's fullscreen with how he says "it doesn't minimize as it should", windowed mode doesn't minimize.

IronHorse

That's why I ask.. He could easily be running it in fullscreen window and not realize

radionaut

yea, fullscreen

Try out "fullscreen windowed"

Do NOT use fullscreen windowed in DX11 mode, it leaks like a bitch when you alt tab. DX9 is fine though.

Never had a problem with it

Alt tab and watch the memory in task manager.

I dont see any

Same thing here, DX11 alttab is funky. Sometimes it minimizes and sometimes it doesnt and just becomes a slideshow.

Would love to see a profile shot when anyone is getting 2 fps

edit: on second thought, given that the cursor is still in the foreground when this happens, i bet its just the window not being focused on. Can u confirm? (also, 2 monitors or just 1?)

DC_Darkling

@ghosthree3 is right.. Mine usually leaks like madness.

yea, the cursor moves around like normal, and i just figured out that clicking anywhere on the screen will minimize the game. technically, two monitors connected but one is a TV that's usually off.

It's Super Effective!

I've had this problem as well recently and I will detail my experiences here, while much of this post is unrelated, it may perhaps bring some insight that might help you.

Recently NVIDIA put out SHADOWPLAY with their latest NVIDIA EXPERIENCE. For those interested, this is what it is

Now this may or may not have been present before Shadowplay even existed... Up until now, I have always ran my NS2 on FULLSCREEN WINDOWED because I ALT-TAB A LOT, and the Fullscreen Windowed allowed it to run smoothly in the background.

Now Shadowplay only works when your game is in FULLSCREEN, so I'm...sorta FORCED to choose between playing in FULLSCREEN , or Play in FULLSCREEN WINDOWED without Shadowplay.

The only workaround I've found, is to NOT ALT TAB IN FULLSCREEN, but if you must, press ALT-ENTER to switch it to FULLSCREEN WINDOWED before alt-tabbing.

But if you do manage to ALT-TAB When you're in fullscreen, you will experience what you are describing above. At this point, all I do is bring up the Task manager on my other monitor (someone mentioned multiple monitors on this post), click on the NS2.EXE process, and hit SWITCH TO... It should restore it's original smoothness, ...and give you a harsh lesson in ALT-TABBING in FULLSCREEN .

It sucks, I know, but until it's fixed, ya gotta make due.

IronHorse

I believe its due to your 2 monitor setup.
Also, that is not a profile shot.

And thanks ISE for the helpful info!
That's a great tip to force a specific monitor to focus

shonan

I have this issue and I only have 1 monitor.

When this happens, the windows cursor appears but clicking anywhere doesnt do a thing, its not minimized like @radionaut explained. Also the game is not focused, you cant open console during the time etc, the game just fills the screen and doesnt allow you to do anything

Heres some profiler shots I managed to grab:

Hmm..
I'll make a report about the issue but i'm not sure there's enough information to go on to fix it.

shonan

This happens most often when in menu.
