Resuming from an ALT+TAB takes more then 30s

Post by xyz »

Every time I minimize Spring and then come back it will take more then 30s for Spring to resume. This is especially annoying in multiplayer games as I will usually desynchronize while waiting.
If the game is paused before ALT+TAB-ing everything is fine (it will switch back in about 5s)

Actually, this is the reason I play in windowed mode.

I think the reason is that the graphics driver moves some data from the GPU memory to disk to free up resources so that you can fire up another graphics app if you want to. Therefore, try defragging the HDD or get a faster one (flash etc). Alt-tab takes about 1 second with my setup (8800GTX+mtron flash).

There is no disk activity while this is happening, the game simply stays there doing nothing.

here is a small video with it, unfortunately the aspect ratio is all messed up, but you'll get the idea:

as you can see winamp runs perfectly fine while the game is switch back, there are no performance issued with the machine. I will have to open a task manager to see what's the CPU usage for spring while it is doing the switch.

Likely to be a driver issue then. Maybe downgrade?

I still think it has something to do with transfer of resources between GPU memory and computer RAM. The disk may or may not need to work depending on how much RAM you have.

I'm using the default settings for the Nvidia driver, except for the disabled "Optimized threading". Not sure if it could have an effect in this case.

Doesn't help, I've seen this behavior since long time ago and changing the drivers didn't help.

I will try this when I get home.

If that does not work, I will have to fix my build system for spring and try to debug it.
Do you know a good GIT client for Windows? preferably with a nice GUI?

Thanks.

Did some more testing and here's what I've got:

"Optimized threading" doesn't help.

-If I turn off Shadows and set water to basic the bug disappears (it will switch back in a second or so)
-If I turn shadows on, but keep the water to basic the switch time jumps to about 10-15s
-If I have water set to anything else than Basic, and the shadows turned off, the switch will take somewhere around 20-25s

Another strange thing is that if I pause the game before alt+tab-ing, the game will restore in 1-2s regardless of my settings.

It has something to do with FBOs and is caused in the nvidia drivers.
I already got the idea to destruct all FBOs on AltTab, but I didn't had the time to test it yet (it isn't as easy as it might sound).

Ok, if you need any help with testing let me know.
