Same here Geof. BFG 8800 GT 512 OC. Which beta drivers are you using?

169.25 beta-but I didn't have any trouble (menus/crashes etc.) with even the ones included with the card (the only problem is the shimmer runway issue in dx10). http://www.mediafire.com/imgbnc.php/1b5baf...b9f427f694g.jpgMy blog:http://geofageofa.spaces.live.com/

Yup, the DX10 runway shimmer is an Nvidea driver deal.

Some additional stability might come from setting two options on the Desktop Shortcut for FSX's Properties/Compatibility tab:1. Disable visual themes2. Disable desktop compositionI've had to set those in order to get FS9 "playing nicely" with Vista32, but haven't (as yet) needed to set them for FSX since my ATI 2400 Pro card doesn't give me the issues in DX10 mode that nVidia owners report...

The Vista extra named "DreamScene" has been known to give some nvidia users stability problems too.

I never have lockups like this. I use DX9 now, but I've used DX10 for quite some time and never had problems. I have ALL Aero options on, I do not hide the taskbar, I have 8800GTX with the 169.25 driver and all is fine (well, not all...). No freezes, no menu problems, nothing. I have however disabled the gadgets-thing at the right of the screen the moment I got Vista, so maybe that was my luck...? I tried to see if setting everything to Classic and hiding the taskbar would cure my blurries (or better said: late loading textures), but it didn't. Apart from THAT all is fine. (Well... I still really really really miss the alpha-fading of autogen... Pity they couldn't restore that in SP2.)

How about you stop trolling already - go annoy another group of people on some other board.James

How about we just keep this thread on topic-an interesting and possibly helpful one at that....thanks!http://www.mediafire.com/imgbnc.php/1b5baf...b9f427f694g.jpgMy blog:http://geofageofa.spaces.live.com/

I had all kinds of lock-up problems - cold hard lockups with the sound going and I had to reboot completely - only with DX10 preview and the latest beta drivers from NVidia with the 8800GT 512 mb OC. Since I went back to DX9 (all under Vista Home Premium) not a single lockup. I think I'll wait until this DX10 thing works the kinks out. I had the same type of lockups using Crysis in the DX10 mode.

>>Some additional stability might come from setting two>options>>on the Desktop Shortcut for FSX's Properties/Compatibility>>tab:>>>>1. Disable visual themes>>2. Disable desktop composition>>Good tip Bill>Thanks a lot :--)When I found that "WinXP Compatibility" mode didn't work for FS9, I tried those two settings and FS9 is flawlessly working with both my 22" widescreen main LCD and my secondary 20" 4:3 LCD screen.
