Crashing...
Have you verified you have the most recent drivers installed for your card? I used to have this problem exactly as you describe it with a different nvidia card and eventually an update to the driver came out and fixed it.
total kick to the gut

This is like having Ra's Al Ghul show up at your birthday party.
The latest Nvidia drivers helped me with a similiar issue. Install those if you havn't already. Older 275.33 drivers are reported to be better if you still have issues with the newest ones and want to try an older driver.
Also, you can try changing settings in nvidia control panel. Go to, manage global settings, power management mode and set it to "Prefer maximum performance".
If you still have issues post in the tech help board area. http://boards.cityofheroes.com/forumdisplay.php?f=578 and follow the sticky guide for asking for help. GL
This seems to have fixed my issue. Thank you SwellGuy! And if I start having issues again, I'll take your advice and post in the correct spot, thanks TerraShock. The help is much appreciated.

Hey, I am having a little technical issue. I am having a strange crashing error and hoping that someone with more knowledge on the subject can help me out. I will be playing, sometimes for less than a minute...other times I will be playing for several hours, there doesn't seem to be any specific event in-game that is causing the crash. The error message I receive is:
The NVIDIA OpenGL driver lost connection with the display
driver and is unable to continue. The application must close.
Error code: 8
I'm not sure what may be causing this...My video card is a NVIDIA GeForce 295 1.792GB with PhysX Technology.
If any other information would he helpful I can try to provide it. Thanks!
