Blurry Aircraft Textures

Hello all,
I recently had to get a complete reinstall of windows and reinstall everything. Prior to reinstalling windows aircraft textures would show up fine and really sharp as opposed to blurry. I have tried changing them to DXT3 format using Dxtbmp as i used to have to do but now that has little or no effect, with little difference for Extended 32 bit 888. I got a quick shot of how they look in the selection menu which is the same as in flight :

It happens on most aircraft from SSTSIM to Posky
Does anyone have any ideas please?
Carl
