Hi everyone, I think I have a possible work-around for a particular game freeze I'm experiencing.

My symptom: Game hangs / freezes, and several seconds later the window closes to desktop. If I am running in 'windowed' mode, I also see a 'AMD Driver has stopped responding message'. If I click the MWO tabbed window icon I can sometimes get back in. The duration of this is about 10 seconds.

My guesstimate diagnosis: The video card has been reinitialized by windows 7 by the "Timeout Delay Recovery" service. This is a feature in windows 7 that detects the video card graphics loop has stopped responding, and issues it a pre-empt command. If the GPU does not respond, the video card is reset, and all video memory is forced to reload (You'll notice the entire desktop redraws too)

My solution: I added a TDR delay setting (set to 8) to overwrite the default value in the windows 7 registry, and rebooted the system. This gives the graphics card more time to respond before being reinitialized. Here are instructions to do so (look under method #1 and 'Let me fix it myself'. Make sure you use the 32 or 64-bit instructions depending on which version of Windows7 you have.

I have had about 6-7 matches now today without a single freeze. I'm hoping this continues to work, and helps anyone else out experiencing this freeze.

Update: Played about 10 more matches without freezing. Seems to be working.

Do you think this applies with windows 8 as well?

Windows 8 certainly still has the feature. And it looks like they offer some more support to the driver itself for handling it. I *believe* it uses the same values as above.


Before doing that though, If you think this particular freeze is your problem, try playing in regular windowed mode (yes its not fun to play in a smaller window with less resolution, but this is beta!) IF you get a "Your Display Driver is not responding" type error message, then I highly recommend trying to increase the TDR delay (whatever its's called in windows 8)

Had seen that MS article before. I'll give it a go and see if it improves what I have been experiencing from time to time.

All I did was enable Vsync, and I maybe freeze up once a day w/ at least a few hours of play.

Yeah, VSync, lower resolution, windowed mode, lowest graphics settings.. Nothing worked for me. Except this registry change.

Oh thank you! I will try this. I have tried everything listed above with no success either and I have a 660 Ti as well.

Make sure to restart after changing the registry I forgot the first time.

Hey! This is a great find. This has so far fixed the issue I had.

I did not have this problem until I did a fresh windows 7 install and re-installed MWO on a new HDD. I did not change my GPU.

Great, I hope it keeps working. Was wondering if this would help *anyone* else.

[Cybermech]

Has this fixed the issue with anyone else?

[DeKamme]

Adding MWO to my firewall's exception list (Comodo) and enabling vsync solved it for me. At least one of these 2 probably has.

Tried the regedit trick, still crash every other matches. Gonna try to Vsync next and see.
