hmm… then we are realy back by the ‘old’ topics related to ATI ( usually about 5/6xxxXT cards and in special VCRUNTIME140.dll ) and may be also topic about driver timeout, which he had in this topic too.
I searched some existing topics which I had in mind. Not less users reported issues with ATI cards. Some can avoid that with limit the fps ( mainly limiting load on the gpu ) , other mentioned specific drivers, and others simple switched to nvidia.
I’am not sure whether in meanwhile a final conclusion about possible issues with ati cards exist.
( partly realy old topics )
