Asus EAH 6850 - Problem with drivers + Blocky edgy video playback

[Zlidrit]

Couple od days ago I installed Asus HD 6850

It works fine with Asus drivers (from CD). Its old version 8.782 - 2010/10/7

All would be fine but I have great video playback problems

Its like most of videos are interlaced. And low quality videos (even flash ones) are blocky - much worse than with my old nvidia 8800



So I decided to instal original ATI drivers - but same happens even with new 11.1

- Card is recognised as 6800 (generic)

- Windows claims it found new audio device but can not find drivers for it ?!

- Most of the games do not recognise the card as modern graphic card ( Fallout 3 New Vegas - will autoset the graphic to lowest quality )

- In most of the games graphic is wrong ( visual problems )



So i had to return to old Asus drivers



PLEASE HELP!!!!



My system is WinXP 32, and my mobo is Asus P5K


p.s

I read lot of people complaining about blocky video playback in 6800 series !

And than the posts cease.... Did they found solution ?

Is it hardware problem ? Is my gfx card broken ?


Some suggested using different cable ? Could this fix it ?



Anyway HELP!!!!

One more question :

Can this be sign of faulty hardware on graphic card ?

I mean except of blocky (when low resolution) video playback and lack of antialiasing (edgy) text. Games run perfect with Asus drivers ...

So could it be just a hardware fault of some element on gfx card ?

If so, it will be hard to prove to the computer shop i bought it from


Hopefully its just drivers or some other problem ?
