Gran Turismo 5 Graphics Fix

Hello! I've recently got Gran Turismo 5 running on Rpcs3 after tinkering with it for a bit, and so far the experience has been good. I get a stable 60 FPS in both menus and races and have experienced no major issues except freezing when buying a car (which I fixed via instructions from the wiki). However I've noticed that some of the graphics are blurry/pixelated, namely the catchfences at tracks like Grand Valley and the badging on most cars. It's more annoying rather than game breaking, but I'm wondering if it's possible to fix and if so how? I've provided images as well as my PC Specs and Rpcs3 settings.

Any help would be much appreciated. Thanks!
