Details, details, details! Please.
- CPU (intel / AMD / any other crap; speed in GHz)
- GPU (Nvidia / ATI / any other crap; exact chipset model = number and some letters, like GeForce 6800 GTS / Radeon 3650 HD)
- The exact version number of the used graphic driver, and if you still rely on the (possibly crippled) existing ones, or if you ever installed some from the graphic card manufacturer at all
As Rappelz appears to be a Windows game, you possibly play under Windows; so your screenshots would be in
C:\Documents and Settings\<your PC login account>\Application Data\PlaneShift\screenshots\
where "Application Data" is a hidden folder, unfortunately. So first set up your Windows Explorer to display hidden files.
The minimum requirements of Rappelz meet the requirements for PlaneShift. So I could imagine that you may have messed some options in the PlaneShift Setup tool, like you might have scaled down the texture quality to e.g. 1/X of the size, which would result in blurry textures.
