TechARP reports NVIDIA's GeForce 181.20 WHQL certified driver isn't working properly with the GeForce GTX 295 in Fall out 3. The reporter experienced lots of crashes in the game, but the issues were resolved by installing an older driver.
While testing Fallout 3 for use in our NVIDIA GeForce GTX 295 review, it kept crashing over and over again. We just could not complete a single test run properly. Sometimes, Fallout 3 would crash on loading the game, or when we encounter a character. Most often though, it would crash when V.A.T.S. mode is activated.
We tried a variety of "fixes" because Fallout 3 has been known to be a little buggy. We also reinstalled DirectX 10, in case it was killed by DirectX 9. Still no go. Guess who was the real culprit?"
