Game crashing: OpenGL message “lost connection”
 

Since I got my GTX260 a couple of years ago I would occasionally get a crash right at the start of a game when host hits fly. It's happened 3 times in the last 2 days, kinda annoying when playing mostly co-ops. The crash message directs me to a Nvidia site with this message:



I have seen this Event Log Message:

The NVIDIA OpenGL driver lost connection with the display driver due to exceeding the Windows Time-Out limit and is unable to continue.

The application must close.

What does it mean?

If you received this message from an application (on a pop up message or in the Event Log), the application was unable to continue rendering because the Microsoft Windows imposed time limit (TDR) was exceeded. This is normally the case when the workload sent to the Graphics Card is greater than what the graphics card can process in the normal timeout of two seconds.

You can find more information in this page:

http://msdn.microsoft.com/en-us/wind.../gg487368.aspx

How can this be fixed?

Two possible solutions to try would be:

Reduce the graphics workload if possible, such as rendering to a lower resolution or with less detail.
Increase the timeout to allow more time to complete the really tough rendering parts. Microsoft provides the information on how to modify the Windows Registry to achieve this.


The card is superior to the one I had, but the game settings are the same I think, so I have not tried reducing game settings. I've tried various graphics card drivers with no success. Does anyone know a solution to this problem?

Hi

Did the last DX entries get cut off when copy/pasting or are they missing in the conf.ini ?

If they are in the conf.ini or you have a back up proceed with the following:

A. Make sure the conf.ini resolution is the same as the monitors resolution, so if the monitors running a resolution of 1920x1080 as in your conf.ini
[window]
width=1920
height=1080
This is correct.

B. Make sure you clean the old driver registry entries and old driver files from your system before installing new drivers.

You can use a driver cleaner utility like this one.

http://www.guru3d.com/files_get/guru...taller),7.html

Run it in safe mode.

http://www.bleepingcomputer.com/tuto...-in-safe-mode/

Clean all video/gpu related drivers and if you had an ATI card in there before run it to clean those entries as well.

Once its clean boot up normally and install the recommended driver and settings.

Only after doing this should you pursue any of the other fixes related to Timeout Detection and Recovery (TDR)
