Hello,
It's time to report this new problem that my system has with Windows 7 and
X-Com 2.
X-Com 2 is a video game which uses bink video player to play scenes.
During the video scene I tried to increasing the volume and also pressed
alt-tab on purpose.
During increasing the volume the game itself minimizes which is a bit weird.
The volume know graphics is supposed to be overlayed by that doesn't happen.
If I switch back fast to the game, sometimes it will work, but sometimes
not.
Sometimes while:
1. Playing X-Com 2.
and
2. A video scene is playing in X-Com 2.
and
3. Alt-Tabbing back and forth.
The following will happen:
1. A black screen appears.
2. Windows 7 seems to loose control.
3. Task manager will not come up.
4. Control-Alt-Delete will not bring up task manager.
5. Some beeping can be heard if I try to press keys or mouse many times.
So some conclusions/observations:
1. The minimizing of the game itself is already weird behaviour.
2 .The black screen could indicate some kind of video/display/graphics
driver problem.
3. Since the problem only occurs during bink video player it could be
related to MMX/XMM/SSE multimedia/video instructions.
So possible conclusions:
1. First of all Windows 7 can't handle a video/display driver crash or bug.
2. It could be a bug in Windows 7 itself.
But for now it's most likely that it's a bug in:
3. NVIDIA's Display Driver.
However I would not rule out a more serious problem in Windows 7 context
switching in relation to special instructions and/or video driver.
My system does have some missing windows patches though and my system is a
bit old/slower than other systems.
AMD X2 3800+ dual core processor and GT 520 graphics carsd.
So first it must be diagnosed if it's just my system/software stack or if
this is happening to other people's system as well.
For now the only solution was to press the RESET button to do a reboot.
So try it out and see if your computer will enter an un-escapable black
sceen during video playback in X-Com 2.
I'd like to know the cause or at least have it solve sometime in future...
Perhaps not even on my old system but future systems... this does smell a
bit like it could be used for denial of service attacks or so ! ;)
Hopefully I am just being delirious about that last possibility ! ;) :)
I will re-post this message on nvidia forum where it probably belongs, but
also x-com 2 forum just in case, I expect to find more testers there then
here ! ;)
(Great game by the way... my review will come when I am finished playing
with it... which will take multiple days possibly... )
Bye,
Skybuck.
