In every valve game iv played...dark messiah, half life, counter strike source and some others...i get this fog affect in which the farther away i stroll away from an object, the grayer it gets, until it full disapears. as i walk up closer to the object, it appears normal again and theres no fog around it with my 8800gtx...i just swapped it with my 7800gtx which was working fine. I havnt come here to ask how to fix it, im coming here to ask if anyone has this similar problem, and if anyone knows if its a defective card, or if its because another patch has to be released to fix the shadowing and fog affects in these games? and yes before you ask, i have the latest drivers, old drivers are uninstalled completely. thanks
