I have been playing the Witcher 2 for more than a few hours (more than I should honestly) and started noticing a rather annoying glitch in The Witcher 2. Some decals that are placed on the floors and walls (blood, scratches, ice from Triss' spells) have large square outlines. This seems to be the only glitch graphics-wise I have noticed. I just updated my video card drivers (I'm using a Sapphire Dirt3 Edition ATI Radeon HD 6950.) Anyone know what could cause this?

(you have to copy and paste the link, it won't work if you click it for some reason.)

Never seen this myself (boy, ATI sure have lots of driver problems).

Btw, your links are missing a backslash which causes the 404 error. You can edit your post and add a backslash on the text enclosed within the "[url=]"

Are you forcing anything in Catalyst Control Center or RadeonPro (whichever you're using)? Also, which drivers are you using?

I'm not forcing anything in Control Center, and I'm using the driver that was on ATI's website for this series of card. I have noticed that this problem only occurs when Ubersampling is on...

Odd. Anyone with an nVIDIA card care to see if this happens while US is on?

Sorry, I don't get what you are suggesting... you said the problem only occurs to you when US is off, and you are asking if NVidia users can replicate this with US on?

Oh, before I forget, is the game patched to 1.2?

I'm an idiot. I thought you were asking was US stood for. I fixed the post, heh. It only occurs when US is on, is what I meant to say. And yes, it is patched to 1.2

Edit: hehe. You fixed your post too quick

I did find a few other forum posts describing a similar problem when ubersampling is on, but the problems they are having don't happen to me...

This is a very similar glitch, but does not happen to me.

No ideas anyone?

Except turning Ubersampling off? Nope. You can contact support at tw2support@thewitcher.com and see if they know what the problem is.

Did you update your drivers because of this problem, or before trying the game? I'm only asking because some problems have been solved by rolling back the drivers to the previous version (sometimes to the one before that).

Try the following hotfix:

Yes, actually. I did update the drivers because of this glitch, but it made almost no difference. I'll try rolling them back right after I try the 11.5b Hotfix.

That will not be very helpful, but i encounter this bug with a nvidia gtx560ti, only with US on. Thep roblem vanish when I turn it OFF...

Noticed with patch 1.3 in the foltest camp, near the wounded soldiers : blood stains on the ground appears like bad decals (like your screenshots).

Here's another glitch but reloading fixed it, good thing I had a save just before the whipping scene :) This is with nvidia 560ti.
The light coming in the window created this huge glare, and it prevented me from going outside, the Open door prompt didnt appear. Maybe the sun was so powerful that day the game wasnt letting anyone outside :)
Anotehr bug I'm finding with 1.3 is more crashing. Once when running in game, and once when trying to delete some old savegames. I'm also continuing an old savegame from a previous patch, hope that's not a problem.
