I've searched in vain here and the nVidia website, so obviously the problem is my own, so maybe someone can offer a suggestion. I was using some older nVidia drivers in my FX5900 Ultra (256 meg) card and was getting some occasional loss of text in the overhead menu in FSX and simultaneously in the ATC window, which rendered it unreadable (blurred, colored graphics blocks in place of the text). Upgrading to the 169.21 drivers (supposed to support the FX series cards) has made the text loss "permanent". I can see the text flash on momentarily but then it switches to the illegible graphics.I'm running 1024x768 on dual CRT monitors in windowed mode, AA and anisotropic filtering handled by FSX settings. 2 gigs of RAM on the mobo and adequate scratch disk space.If anyone has encountered these problems, please let me know. The new drivers make the panel display more "stable" (i.e. no "hot spots" where the panel window flashes on/off as it did with the older drivers) but I can't read the ATC window text.

I have Core 2 Duo E6850 at 3Ghz, XFX GeForce 8800GTwith driver ver 167.26 and Vista 32 Utimate and 4 Ghz Ram. I had same problem of menue text goingto blocks. The problem was "out of memory". Somehoweven with 4 Ghz this was happening. I run in full page.Since you are in windowed mode check the Task Mgr to see what the CPU is doing. Also check AVSIM for "OOM"out of memory. How did I fix it? I do not know but no problems lately.

I have an 8800GT, am using the latest beta's, and am getting the same thing, but only in 'full screen' mode. In 'windows mode' the text appears as it should. This has been an issue with all the drivers I have tried thus far.

I've checked DirectX and have 9c. I'm running the 169.21 nVidia drivers. Task manager shows no problems - plenty of unused RAM and page file space. I tried the Microsoft suggestion of pulling back hardware acceleration two notches with no improvement. I'm currently pulling back on my graphics settings one at a time to see if that will reduce the graphics load (that will take some time because I do have them set rather high). I'll check in later if I find a solution.Thanks, all.
