Back in the days of Premiere Elements 9.0/9.0.1 BadDrivers.txt file took on a life of its own after I started the following thread on that display card error.

The following is a significant excerpt from that thread in which Daksha123 went into BadDrivers.txt file and what it is all about
(It was/is my understanding the Daksha123 was writing at the time from Adobe.) Dakasha in an earlier post in that thread gave the BadDriver.txt deletion fix  which worked for me and so many others. Mine at least on a permanent basis.

If GPU card is available on a system, PRE9 uses that card for faster and smoother playback. If the driver version installed on the mechine is not compatible with PRE9,  that driver version is stored in BadDrivers.txt file and then PRE9 runs in pure software mode to avoid any further crashes/problems due to that bad driver. It generally happens when driver promises to support some GPU capabilities but actually doesn't support those capabilities at all...
In this scenario, PRE9 shows a warning message to users that driver installed on the machine is not compatible and user should update display driver.  Generally updating to latest display driver should solve this problem: if latest driver is compatibe with PRE9, PRE9 will run in normal mode with faster and smoother playback. (As in case of Hunt & jjjbbbqqq)
Sometimes, as in case of Ron, even the latest driver shows *inconsistent* incomaptibility with PRE9. And in this case deleting "BadDrivers.txt" file should work.
If an user is observing consistent incompatibility (even after deleting "BadDrivers.txt" file the same message pops up again) with the latest driver then that driver is really a bad driver for PRE9 and with that driver PRE9 will always run in pure software mode. There is a very little probability of this kind of card and driver.
So in summary,
if user is getting warning message : "We have detected an incompatible display driver. To get a better and faster playback performance, please update your display driver "
1. User should try to get the latest driver for the card available on those systems,
2. If user is getting same message again even after updating the driver, try to re-launch app after deleting BadDrivers.txt file,
3. If even deleting “BadDrivers.txt” is not working and they are again getting same message, then that driver is really a bad driver for PRE9. PRE9 will run in pure software mode in that case.
