My monitor is designed for use with amiga soft
) His native resolution is 1280x1024 /2 640x512 /2 320x256 - it's exacly 1:1 square pixel but windows drivers don't work with these resolutions (320x256, 640x512). When use native resolution and choose resolutions with heigh 256 and 512 scalled to 1024 then picture is perfect but in directdraw, in direct3d there are many pixels lost. My GPU is ati hd5770 and why d3d don't work propertly ?
