New Ati 4850 problems in Win7
Hello to all,
I`m new to Win7 and this forum, ofcourse :) but tis good to see i have a place where to ask for help and maybe even fix something.
Before i upgraded to a Ati 4850 i had a nvidia 9600GT that worked fine...in Vista. When i got the 4850 i did a clean install of Windows 7 build 7100 RC .
I installed all the new drivers for mobo, audio, graphics etc...defraged, installed antivirus and my ussual programs and games. All ok ...
...ultill i played my first movie in VLC, its very pixelated. Other players work fine, just VLC is pixelated, i looked around its settings but nothing helped.
Another problem i discovered and its big, I cant use 75hertz on my monitor.
If i use 75 i get flickering red dots all over my screen, in my desktop or in games. Its very annoying since most games come with standard 75hz i have to manually adjust them in regedit to use 60. 60 works great. Before the 4850 upgrade i could use 75 with my nvidia card.
Another problem i cant explain is somewhat bad performance for my video card. Ofcourse ATI drivers for win7 now are bad but still i get same performance i got with my 9600GT. Around 9500 points in 3DMard06. Same score i was geting with the 9600GT. Still posibly my CPU is draging me down...but still thats to much draging down ...:)
Hopefully the new 9.5 Catalyst drivers will solve some issues but in case they dont , what will i do ...
Any advice or help, maybe you seen these problems before, i dunno ... plz tell me
