Just wondering really, in Vista, when UAC kicks in and asks you to click to confirm an action within Windows does anyone elses screen kind of "jump" to the faded black background. What I'm getting at here is that there is no transition effect, no fade, no smooth entrance of the said faded, slightly blackened background, it's as if its forcing the video hardware to restart each time which results in a screen flicker effectivley. Is there any way to fix it other than turning off UAC? Hopefuly my post makes sense
The secure desktop doesn't allow access from WDDM drivers, so Aero is turned off and the flicker you see is rendering mode being changed from dx9 to standard GDI. No way to change that (yet) but I turn the secure desktop off (it annoys me). If you're running business/ultimate go into the group policy editor and look for the secure desktop setting to turn it off. If you're running Home, then it's a registry key; HKEY_LOCAL_MACHINE/SOFTWARE/Micrsoft/Windows/CurrentVersion/Policies/System and set PromptOnSecureDesktop to 0. If you reinstall a lot then it's worth remembering that.
why go to the registry... you can disable UAC from the control panel, within the account manager panel.
Because the reg key way simply turns off the secure desktop (when it goes all dark). Disabling it means it's all disabled (including registry/file virtualisation and IE protected mode). Disabling UAC is a bad idea and I strongly urge you not to do it. If the prompts annoy you (they don't come up often, and if they do you should probably email MS about it) then using my reg key way, or gpedit.msc if you have business/ultimate then you can turn auto elevation on so you'll never see another prompt. You will be slightly less secure, but more secure than having UAC turned on.
Ahh, well that explains why it flickers. I guessed it may be some kind of graphical fall-back but its just a shame that it's really quite ugly when it does it. Cheers for the advice though, I guess its a toss up between becoming slightly less secure and getting frustrated at the flicking hurting my head every time it does it (which is pretty frequent, most of the apps use seem to want elevation to admin (SOE games). Sadly though vista won't be my main OS for some time, it kills the performance in planetside to the point of unplayable (it makes me loose about 30fps) and that's with the sidebar and other such resource eating apps switched off. Probably has something to do with the fact that I have to run it in 98 compatibility mode however.
no, the slow down is because of drivers are not optimized. Rememberer that XP was out since 2001. Programmers know how to develop games, and drivers for it. Not vista, not yet anyways. Every time new drivers will be out, you should see your device perform better and better.
Recent nVidia drivers (158.18) have been excellent. It's awful that they've had over 6 months to do this though.
I have also disabled UAC. Im confident that im not a moron so I know what I am downloading and running. no offence to anyone that uses it
They were quite helpful (Test Drive Unlimited does not crash every 5 minutes now! =) Oh and it's not 6 months, it's more like 2 years since Beta1. I was so excited about Vista, that I managed to get Vista running in summer of 2005 (only sound drivers did not work). And most companies did not bother enough to work on creating drivers and improving compatibility until very late betas and even full release. Shame on them.
I don't have Vista yet, (but I did play with all the public betas of Vista)... I think it's about being "moron" or not, but maybe it is the case of "better be safe then sorry". But even then, I know that Vista has the ability to go "back in time". (to the last restore point that you created) so you can prevent a virus infection.
