Hi,I have a rather weird problem with my setup.When flying the FS (and only then) and entering densly textured area (such as commercial dense scenery or sky full of clouds - so lots of objects to be rendered) I get those LCD monitor flashes.They are not like 'render to texture on' kind of flashes when the whole screen goes black for a split of a second, this is more like a colourful, reddish horizontal lines flashing for half a second or so.It's a pity I cannot catch it with a screenshot utility as it is too rapid and too random at the same time.It only happens in FS and I run it windowed mode.I was using DXT clouds, but also tried the 32bit clouds with Render to Texture off and it did not change a thing.Your help would be appreciated,Dom

Hi Dom, I was going to propose you post in the other hardware forum when I saw you already did... :-) By any chance, did you drop the files mentioned in the following thread? http://forums.avsim.net/dcboard.php?az=sho...13692&mode=fullGood luck and kind regards Jaap

Hallo again Jaap,I had these files in my FS folder long time ago and indeed it caused a lot of problems but since then it was long removed.ThanksDom
