Yellow Terrain/Invisible Mobs

http://i.imgur.com/64uPp1V.jpg

I have been having this for days, i have re-installed the game and it happens every few minutes like 30 mins+ or so. sometimes bosses like Nidhogg will just be invisible and it gets very frustrating. I have updated all my drivers and i have tried looking up how to fix this to no avail. Restarting the game only helps for a little bit than it reverts to yellow terrain/missing mobs/NPC. Also, my mount is invisible

PC Specs:

AMD FX(tm)-6300 Six-Core Processor
Speed 3.5 GHz
RAM 8.0 GB
AMD Radeon HD 7800 Series

Wow, I am sorry to hear you are having this problem.

Based on what is actually yellow, it looks more like the shaders and shadows are not working or loading.

Since you listed an AMD card, I am assuming you have a Crimson driver. I am not too familiar with those, but somewhere in the Crimson driver settings like where you adjust the cross-fire settings, you should see options for the profiles for the graphics. There, you can check any of the settings to see if any of these adjusted could solve your problem.

Also see about adjusting the settings for the Display in the Crimson driver.

Sorry that I could not be much more help.

no problem, it sucks cause i want to come back and play and start stormblood but with texture glitches like this it really turns me off :/
