ATI Drivers ... use WDDM or ATI???  

when i installed Win7 it had the WDDM drivers installed they seemed stable didnt have any crashes in short time they were on but...

when i played games eg L4D (via steam), msg came up saying drivers not up to date

so i decided to DL latest ATI drivers now i get constant driver crash (prob once an hour ish), but only to extent black screen to 2 secs and then back all good, only real prob is it resets my Fan adjustmens via Rivatuner back to std

should i go back to WDDM drivers? are they worth reverting or should i stick out ATI ones, or is there a better option

...did drivers not install properly, anyone else got this problem??

EDIT: Video card = ATI 2900XT

Thanks

ATI drivers should be WDDM
(if not you'll not have Aero working)

I suppose you talking about WinUpdate Vs ATI webiste driver.

Drivers on WinUpdate are often "old" ATI drivers with more reliability test, and stability proof.

You can see via device manager which driver version you have for each one and compare. If the ATI drivers give you some trouble, so you mays go back to a previous one, more stable. Seven driver are still beta (even on WinUpdate) so you may have issue with one, juste installe and use the one which work better for you.

just a thought:

I was having issues with my ATI driver so I tried rolling back the driver via Device manager and had a BSOD. I am not sure if the beta driver or the ATI driver caused it but I thought I would just give ya a heads up on it.

I was pondering this same thing except it was over Nvidia's drivers for Vista64 or the driver offered by Windows Update (WDDM). I found that the Vista64 drivers work much better (for now anyway).
