GeForce 280.26 driver causing FFXIV to crash

[Baldur]

Final Fantasy XIV has been crashing a lot for me ever since I installed the GeForce 280.26 driver update. Most of the time a message appears after the crash saying "unable to detect DirectX device" or something similar. Once, Final Fantasy XIV crashed for no apparent reason. I recently rolled back to the previous driver version and, so far, I have not experienced a crash, though I haven't played long enough to know if this fixed the problem for sure. If I experience another crash, I'll let you know.

In case if this is important, here are my system statistics:

Operating System: Windows Vista
Processor: AMD Athlon 64 X2 Dual Core Processor 4600+
Memory (RAM): 2.00 GB
Graphics: NVIDIA GeForce GTS 250
Gaming Graphics: 1791 MB Total available graphics memory

With the above statistics I can run Final Fantasy XIV quite (spelling?) well with everything set to standard. FPS is nearly perfect outside of cities, but I experience quite a few skips in cities. Nothing that renders the game unplayable for me though.

The issue you had with the Direct X 11 ...did you get the update for your GPU from Nvidia or Microsoft? I had the SAME issue when I did them, yes I knew better but did it anyway, with Microsoft. The new ones you guys are having issues with I got from Nvidia themselves and no issue at all. Could be a bad driver install as most have said or could be the provider of those drivers as well. Just my 2 cents since Baldur reminded me. And mine happened just playing on Civ V which is NO where NEAR FFXIV as far as GPU intensive.

I believe I got mine from NVIDIA. The NVIDIA Settings icon in the notifications toolbar displayed a message telling me that a new driver update is available. I opened the program, opened the Help tab, clicked on Updates and went from there. I can't tell you any further details because, after the rollback, the program won't open the Updates window anymore...
