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.

PC SPECS: 

AMD Ryzen 5 5600X Processor
Nvidia GEFORCE GTX 1660 Super graphics card
ASUS TUF GAMING X570-PLUS Motherboard
16GB Ram

Any help would be much appreciated. Thanks!

I'm happy now. lots of setting twaking and new builds.   Finally latest  emu build working great (i don't dare upgrade it)
Older version of the builds i was suffering with unstable glitches on graphics and freezing and stuttering audio sometimes. Now it's stable and game looking great and just as good on the ps3.
I had a couple of freezes early after starting up from defult setting when i was in options in the game. Then i made a custom settings from defult and did a fiew lucky tweaks.
I added the config folder and the save file (B-spec at level 33) to this post so you can try it too.

S SYS: Updates found at /dev_hdd0/game/BCES00569/  

I also have upgraded the game to 2.11 and running GT5_2.11_Master_Mod_1.9.1_(EU-BCES00569) so it is probably a bit heavier to run than defult.

BTW, here is a tip, Grinding up B-spec drivers level can be a bit tedious, so then you can use the  Sebastian Vettel car with sport or racing tires to do the job faster. 
I start a endurance race. Then i right click on the game in the UI, and select change custom configuration then on gpu setting i set framelimit to 30 (less powerdraw/taxing on the gpu/cpu HW). And on audio setting i disable sound (so i don't get disturbed doing other stuff on the pc). Then i select Advanced setting an adjust VBlank frequency from 60hz to 480 hz to speed up the race 8 times, so then the grid goes way faster. (you can go higher hz but it might lead to game crash. (I don't save this new setting, just close the setting window).
I also selct follow camera to a slow car so the emulator dont havve to render new location on track so fast as vettel's car do.

Also my ps4 contoller working great on RPCS3  and way better than on Pcsx2 and using GT4 game: The analog stick felt almost like steering with a digital innput pad and way too twitchy/fast. (if i redused speed to under 100% i then could not give full trottlr and turn with analog stick, and way too slovw return speed on the wheels).
On  RPCS3 i could reduce the deadsone so i got more range to play with controlling the cars. so way more smoother transition from no input to turning  the wheels.tr


I made a demo video on youtube , filmed my 4k 65 inch TV with my phone, so not the best quality
