Currently my GPU, 8800 GTS 640 is not overclocked. I have started to notice white flashes in certain situations. For example, starting up at a country airport in Alaska and use the hat switch to look around it spot view - get some quick white flashes. This did not happen before. Happens with the 174.74 and the 180.4x driver also.

99% of the time all is well and this is more of a "what's happening" rather than an "OMIGOD".  Smiley

Assuming the vid card is not going bad - would some anomaly in the system overclock affect the GPU?

Just as an aside, I know how to cause my system to reboot - Smiley

fly the SectionF8 F-86 FSX port over the Los Angeles Basin at 1500 feet 550kts doing a series of aileron rolls while using TrackIR to try and follow the horizon.

No blurries, no pauses - just a click - reboot. Of course, since I don't fly that way regularly it's not a problem - just an interesting aside.

Like the old story:

ME: Doctor, it hurts when I do this.
Doctor: Then don't do that.

FSX runs fine... the problem
is you or your system

The flashes can be from the buss and the amount of bufferpool reserve, and, there are known issues with FSX and the airport/aircraft lights showing quick black boxes after SP2

I have sometimes exceeded the BP reserve and seen AG show spikes as I pan around the aircraft until all scenery loads... also saw that with some drivers and BP set lower

what you are seeing has nothing to do with overclocking.

Try backing down bufferpools


SP2 introduced some strange problems which tend to vary from driver to driver release

I am using driver 180.84 now

didn't think it did - good! Will try reducing the BP - not at my system - IIRC I had it up around 32M.

btw, you meant 180.48 not .84 correct?
