I implemented a Visualisation a few months ago on an old XP Machine with SlimDX and an old Geforce. It worked perfectly. Now i startet the stuff on an new Computer:
Windows7 Intel I7 Amd HD6350
It's still an DirectX 9 Device. But the Resolution now is very low!!! I tested a screenshot in Photoshop. a Pixel in the visualisation consists of 4 Pixels on my Screen. The Control i draw to has 1000 x 1000 Pixels, but Slimdx Stretch 500x500 Pixel to this control... Antialiasing and stuff were on and off - nothing happened.
Anyone an idea? :-/
