Meh... all the problems started with that damn 8.1 update. However it's weird... cuz i'm running exactly the same drivers as I was before (oldest possible version) - if i put something different the drivers go totally crazy.
Tried a manual install of DX9. Still the same problem. Actually discovered that i can't run anything (different games) with the radeon. So there is something srsly wrong. My guess windows is doing something bad with the switchable graphics (had something similar with win 8 beta).
I'm already running FF on low settings. Hard part is - i can't even get the game started with it. Once i press "play" it just dies.
Well there is no reason to contact ATI actually. Cuz what ATI says is that they are not responsible for the graphics drivers in laptops. It is each vendors responsibility to make and distribute their drivers for laptops... and dell's not gonna do it
Meh... looks like the simplest solution would be to roll back to Win8.0 or just reinstall win.
Edit: turns out you can't just roll back since win 8.1 is practically a new installation of win.
