Hello, I was wondering if anyone with any know-it-how could help me find the answer to my problem. The issue is that when using "SEUS-v10.1-Standard" shaders I am getting irregular textures and colours. Please see the screenshots below for more information.

The correct version of Optifine is being used, and I have tried changing the texture pack to see if that helps (which it hasn't) and I am currently running an AMD FX-6300 processor with an AMD 7870HD Radeon graphics card overclocked to 1.15GHZ. I have 4 Gigabytes of RAM assigned to Minecraft and cannot understand why this problem is persisting; my friends also run these shaders and have not encountered these problems.

Thank you to anyone who has read this.
