Wowww... it is really blurry... not a geometry problem but a texture one...
Was first thinking of your graphic card but your card is supporting fully shader 5.0... only ATI card who can maybe lead to problem is the serie ATI mobility X1000 serie... the X1000 serie is say to be compatible with shader 3.0 but miss one of the instruction called "Vertex texture fetch" and replace it with their own "render to vertex buffer" ( if sins .fx files don't use vertex texture fetch, the ATI x1000 serie is compatible with sins ) ...
Go to your .../Local Settings/Application Data/Ironclad Games/Sins of a Solar Empire/Setting and open your user.setting file with notepad... if all your setting are on highest, you need to read something like :
TextureQualityForShipColor 3
TextureQualityForShipData 3
TextureQualityForShipBump 3
TextureQualityForModuleColor 3
TextureQualityForModuleData 3
TextureQualityForModuleBump 3
TextureQualityForPlanetColor 3
if you have lower value, edit and save...
For more help from me, you will need to wait as i am waiting for my money to be on pay-pal for pre-order rebellion... maybe reb dev will have interest in your case since it seem related to the new shader for the ship fx ( shader 2 have become shader 3 )
