Company of Heroe's and Opposing Fronts both have ALT-TAB BUG.

Hello,

When switching many times between the game and windows COH develops a "bug".

When starting a multiplayer game, the game "stutters" !

Restarting the game solves the issue.

Bye,
Skybuck.

That's not the alt tab bug, you idiot. That's your cache.

Never heard of such a thing, probably nonsense too.

I could imagine the processor's cache is emptied, filled with other stuff...
when alt-tabbing to windows.

Surely the processor cache will be re-filled with coh code.

It probably isn't even swapped out since it's running in the background.

Me thinks it's a timing issue.

Bye,
Skybuck.

Hmm maybe you mean some other kind of cache.

Maybe graphics cache.

Gonna investigate that some more.

Here is link about somebody writing something about Company of Heroe's and
the
"alt-tab problem"

http://forums.guru3d.com/showthread.php?threadid=240317

Bye,
Skybuck.

Oh well forget that thread.

Not much info in there.

I am seeing "stutter"

Once the "stutter" happens it can't be fixed by alt-tabbing.

Only restarting the game fixes it.

To me it seems like:

1. Threads keep running and aren't cleaned up properly.

(I could check this in task manager under threads... I'll do that
sometime... if "dangling" threads is causing this it will show up in an
increased ammount of threads running)

2. Timing problem.

Timing code in the game is not updated properly... however seems kind weird
since when returning to the game this should be solved me thinks or maybe
just bad coding or something.

3. Something else ?

I have installed the lastest AMD Processor Driver.

AMD has not updated it's main website... but the driver is on another link.

I don't think that matters much because it's the same driver I think, just
installer is different... but who knows..

One thing I did do is:

I installed X2 Core Optimizer driver.

I am gonna play the game with it installed for a while.

The performance indicator in the game is now on all high.

Another dude said it solved problems for him as well..

So who knows.

I just hope my windows booting time doesnt get bad as it did back in the
past with this core optimizer driver

Bye,
Skybuck !

You installed it before and complain about slow bootup times.
Then say the driver has not changed. Then you Install the same driver again
and hope it does not slow down your boot time.

So what's changed from the last time you Installed this driver ?

Now I know your a troll.

I am not certain if the core optimizer was the cause of it.

I think so, but I am not sure...

If the boot time becomes slow again then I am pretty sure.

For now I plan on playing some more COH so it's the possible price to pay.

If I am done with COH and boot times get worse I simply remove it again

No big deal !

If on the other hand boot time remains ok... then maybe other games will
benefit from it.

Maybe airborne... but I don't like to play another ww2 shooter... I am done
with that

Bye,
Skybuck =D

Well that didn't last long.

Dual Core Optimizer probably caused the following system crash:

So now I have to choose between restarting the game, or restarting my
computer and crashing during games.

So I rather restart the game instead.

End conclusion:

De-installing dual core optimizer

Hopefully games in the future stick with windows api and don't use asm and
rts clock instruction or something like that

Skybuck.
