Losing graphics mid flight

[Clipper]

Can anyone identify this issue...I have a Nvidea 5200fx 256k card. I'll be flying for a few minutes, graphics are perfect, then everything blurs. Most of the detail in the scenery is lost, althogh the plane remains crisp. I know there is a config tweek to allow the card to empty graphics when you leave an area, anyway, i'd appreciate any suggestions or tips you may have.

Thanking you all in advance, Clipper

Is this a problem thats recently appeared?

If so, I'd try new drivers, failing that, I'd seek a friend with a similar card to see if your current card is the culprit.

9 times out of 10, this is a driver corruption issue in my (limited) experience.

Ay, almost certainly your drivers will need updating. That failing have you un/installed anything recently that could have written over or deleted them?

I'm quite sure you're both right, it just started happening. I'll install the updated drivers. Thanks a lot...
